For those groups that are able to form isomers, for example, n-propyl and isopropyl, the term means any of the possible isomers and is not intended to limit to one isomer.

As used herein, the term "salt complex" refers to a molecular entity formed by a loose association involving two or more component chemical compounds. In the present disclosure, the salt complex is believed to be a salt formed by the protonation of at least one of the amine groups of the oligoglucoslamine structure by the carboxylic acid. For example, Product 19 may exist as any one or more of the salt complexes represented by the following structures, the dotted line being used to indicate the formation of the salt complex:

The term "agricultural composition" as used herein refers to a composition comprising the salt complex of Structure A, Structure B,

Structure C, Product 19 or Product 20 and further comprising one or more substances formulated for at least one agricultural application. Agricultural applications are any application that enhances plant performance, such as, for example, plant health, germination improvement, growth

improvement, yield improvement, pest control, disease control and resistance to abiotic environmental stress.

As used herein the term "biologically effective amount" refers to that amount of a substance required to produce the desired effect on a plant, plant propagating material and/or plant part, such as, for example, germination improvement, growth improvement, yield improvement, pest control, disease control and resistance to abiotic environmental stress. Effective amounts of the composition will depend on several factors, including treatment method, plant species, propagating material type and environmental conditions.

Foliage as defined in the present application includes all aerial plant organs, for example, the leaves, stems, flowers and fruit. As used herein, "percent germination" refers the percentage of seeds that germinate after planting or being placed under conditions otherwise suitable for germination. The term "accelerate the rate of germination" and its equivalents refer to an increase in the percent germination of experimentally treated seeds compared to seeds

designated as experimental controls as a function of time. In the

Examples presented herein, seed germination rates were determined with laboratory-based germination assays conducted under optimum conditions for germination wherein germination percentages were determined at a specified time following initiation of the experiment. General descriptions of seed germination tests can be found in the Handbook of Seed

Technology for Genebanks, Volume I. Principles and Methodology, R.H. Ellis, T.D. Hong and E.H. Roberts, Eds., International Board for Plant Genetic resources, Rome, 1985, pp. 94-120 and the Seed Vigor Testing Handbook, Contribution No. 32 to the Handbook on Seed Testing prepared by the Seed Vigor Test Committee of the Association of Official Seed Analysts, 1983.

As referred to in the present disclosure and claims, the term

"propagating material" means a seed or regenerable plant part. The term "regenerate plant part" means a part of the plant other than a seed from which a whole plant may be grown or regenerated when the plant part is placed in agricultural or horticultural growing media such as, for example, moistened soil, peat moss, sand, vermiculite, perlite, rock wool, fiberglass, coconut husk fiber, tree fern fiber or even a completely liquid medium such as water. Regenerable plant parts commonly include rhizomes, tubers

(including seed potatoes), bulbs and corms of such geophytic plant species as potato, sweet potato, yam, onion, dahlia, tulip, narcissus, etc. Regenerable plant parts include plant parts that are divided (e.g., cut) to preserve their ability to grow into a new plant. Therefore regenerable plant parts include viable divisions of rhizomes, tubers, bulbs and corms which retain meristematic tissue, such as an eye. Regenerable plant parts can also include other plant parts such as cut or separated stems and leaves from which some species of plants can be grown using horticultural or agricultural growing media. As referred to in the present disclosure and claims, unless otherwise indicated, the term "seed" includes both unsprouted seeds and seeds in which the testa (seed coat) still surrounds part of the emerging shoot and root.

The term "rhizosphere" as defined herein refers to the area of soil that immediately surrounds and is affected by the plant's roots.

As used herein, the term "treating" means applying a biologically effective amount of a Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex, or a composition containing a Structure A,

Structure B, Structure C, Product 19 or Product 20 salt complex, to a seed or other plant propagating material, plant foliage or plant rhizosphere; related terms such as "treatment" are defined analogously.

The term "yield" as defined herein refers to the return of crop material per unit area obtained after harvesting a plant crop. An increase in crop yield refers to an increase in crop yield relative to an untreated control treatment.

The salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20 can be produced by contacting the polyamine portion of Structure A, Structure B, Structure C, Product 19 or Product 20 with the carboxylic acid of Structure A, Structure B, Structure C, Product 19 or Product 20. The polyamine portion can be produced in a variety of methods. In one example, US Patent Number 7,485,718 describes method for producing the polyamines of Structure A, Structure B,

Structure C, Product 19 or Product 20. The carboxylic acid portion can also be produced using a variety of known methods. Preparations of both saturated and unsaturated fatty acids are known in the art. A two-step process of contacting the saturated or unsaturated fatty acid with an amino acid ester followed by deprotection of the ester can produce the desired carboxylic acid that can be used to form the desired salt complex. The polyamine and the carboxylic acid can be contacted with one another in an appropriate liquid carrier to form the desired salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20.

Agricultural compositions comprising the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20 can be applied as a seed treatment formulation, as a seed coating composition, as a foliar formulation, as a sprayable foliar formulation or as a formulation suitable for treating the growing medium. Such formulations typically contain from about 10^"3 M to 10^"12 M of the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20. In other embodiments,

formulations contain from about 10^"6 M to 10^"10 M of the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20. The locus of the propagating materials can be treated with a Structure A,

Structure B, Structure C, Product 19 or Product 20 salt complex by many different methods. All that is needed is for a biologically effective amount of a Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex to be applied on or sufficiently close to the propagating material so that it can be absorbed by the propagating material. The Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex can be applied by such methods as drenching the growing medium including the propagating material with a solution or dispersion of the Structure A,

Structure B, Structure C, Product 19 or Product 20 salt complex, mixing the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex with growing medium and planting the propagating material in the treated growing medium (e.g., nursery box treatments), or various forms of propagating material treatments whereby the Structure A, Structure B,

Structure C, Product 19 or Product 20 salt complex is applied to the propagating material before it is planted in a growing medium. In some embodiments, the agricultural composition can provide an increased rate of germination, an increased rate of seedling emergence, an increased rate of radicle growth, an increased rate of early growth, increased pest control, increased disease control, increased plant height, increased vigor, increased resistance to abiotic environmental stress, and increased biomass and/or yield. In other embodiments, the agricultural composition can provide increased yield.

In some embodiments, the agricultural compositions comprising the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20 can be used as a seed treatment formulation with an

agriculturally suitable carrier comprising at least one of a liquid diluent, a solid diluent or a surfactant. A wide variety of formulations are suitable for this disclosure, the most suitable types of formulations depend upon the method of application. As is well known to those skilled in the art, the purpose of formulation is to provide a safe and convenient means of transporting, measuring and dispensing the agricultural agent and also to optimize its efficacy. The use of agricultural compositions comprising the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex, including seed treatments, can provide increased plant growth, an increased rate of germination, an increased rate of seedling

emergence, an increased rate of radicle growth, an increased rate of early growth, increased pest control, increased disease control, increased plant height, increased vigor, increased resistance to abiotic environmental stress, and increased biomass and/or yield when compared to an untreated control.

Depending on the method of application useful formulations include liquids such as solutions (including emulsifiable concentrates),

suspensions, emulsions (including microemulsions and/or

suspoemulsions) and the like which optionally can be thickened into gels. Useful formulations further include solids such as dusts, powders, granules, pellets, tablets, films, and the like which can be water-dispersible ("wettable") or water-soluble. The salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20 can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation comprising the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20 can be encapsulated (or

"overcoated"). Encapsulation can control or delay release of the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20. Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High-strength compositions are primarily used as intermediates for further formulation.

The formulations will typically contain effective amounts of the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20, diluent and surfactant within the following approximate ranges that add up to 100 percent by weight.

Each of the references to the above patents and

applications are hereby incorporated by reference. The agricultural compositions comprising the salt complex of

Structure A, Structure B, Structure C, Product 19 or Product 20 can further comprise one or more signal molecules. In plants of the Leguminoseae family, the symbiotic interaction between the plants and nitrogen-fixing bacteria of the Rhizobiaceae family ("rhizobia") enhances plant growth and crop yield. The symbiotic interaction is initiated when a plant releases flavonoid compounds that stimulate rhizobia! bacteria in the soil to produce lipochitooligosaccharide signal molecule (LCOs).

LCOs are signaling compounds that induce the early stages of nodulation in plant roots, which lead to the formation of root nodules containing the nitrogen-fixing rhizobial bacteria. Application of a LCO to seeds of legumes and non-legumes can help to stimulate germination, seedling emergence, plant growth and yield in crop and horticultural plant species. LCOs have also been shown to enhance root development. Foliar application of LCOs has also been demonstrated to increase photosynthesis, and fruiting and flowering in crop and horticultural plant species.

LCOs consist of an oligomeric backbone of β-1 ,4-linked N-acetyl-D- glucosamine ("GlcNAc") residues with an N-linked fatty acyl chain at the nonreducing end. LCOs differ in the number of GlcNAc residues in the backbone, in the length and degree of saturation of the fatty acyl chain, and in the substitutions of reducing and nonreducing sugar residues. LCO structure is characteristic for each rhizobial species, and each strain may produce multiple LCO's with different structures. LCO's are the primary determinants of host specificity in legume symbiosis.

In one embodiment, the bacterial strains disclosed herein can be used with one or more LCOs. In one embodiment, the disclosure relates to the agricultural composition and further comprising a bacterial strain disclosed herein and one or more LCOs. In still yet another embodiment, the agricultural composition can further comprise one or more LOCs.

Biol Fertil Soils 40:36-43). In another particular embodiment the Penicillium species is P. gaestrivorus, e.g., NRRL 50170 (see, Wakelin, supra.).

In some embodiments, more than one phosphate solubilizing microorganism is used, for example, at least two, at least three, at least four, at least five, at least 6, including, for example, any combination of the

Acinetobacter, Arthrobacter, Arthrobotrys, Aspergillus, Azospirillum,

Bacillus, Burkholderia, Candida Chryseomonas, Enterobacter, Eupenicillium, Exiguobacterium, Klebsiella, Kluyvera, Microbacterium, Mucor, Paecilomyces, Paenibacillus, Penicillium, Pseudomonas, Serratia, Stenotrophomonas, Streptomyces, Streptosporangium, Swaminathania, Thiobacillus, Torulospora, Vibrio, Xanthobacter, and Xanthomonas, including one species selected from the following group: Acinetobacter calcoaceticus, Acinetobacter sp, Arthrobacter sp., Arthrobotrys oligospora, Aspergillus niger, Aspergillus sp., Azospirillum halopraeferans, Bacillus amyloliquefaciens, Bacillus atrophaeus, Bacillus circulans, Bacillus licheniformis, Bacillus subtilis, Burkholderia cepacia, Burkholderia vietnamiensis, Candida krissii, Chryseomonas luteola, Enterobacter aerogenes, Enterobacter asburiae, Enterobacter sp., Enterobacter taylorae, Eupenicillium parvum, Exiguobacterium sp., Klebsiella sp., Kluyvera cryocrescens, Microbacterium sp., Mucor ramosissimus,

In some embodiments, two different strains of the same species may also be combined, for example, at least two different strains of Penicillium are used. The use of a combination of at least two different Penicillium strains has the following advantages. When applied to soil already containing insoluble (or sparingly soluble) phosphates, the use of the combined fungal strains will result in an increase in the amount of phosphorus available for plant uptake compared to the use of only one Penicillium strain. This in turn may result in an increase in phosphate uptake and/or an increase in yield of plants grown in the soil compared to use of individual strains alone. The combination of strains also enables insoluble rock phosphates to be used as an effective fertilizer for soils which have inadequate amounts of available phosphorus. Thus, in some embodiments, one strain of P. bilaiae and one strain of P. gaestrivorus are used. In other embodiments, the two strains are NRRL 50169 and NRRL 50162. In further embodiments, the at least two strains are NRRL 50169 and NRRL 50170. In yet further embodiments, the at least two strains are NRRL 50162 and NRRL 50170.

The phosphate solubilizing microorganisms may be prepared using any suitable method known to the person skilled in the art, such as, solid state or liquid fermentation using a suitable carbon source. These culture methods may be used in the preparation of an inoculum of Penicillium spp. for treating seeds and/or application to an agrononnically acceptable carrier to be applied to soil. The term "inoculum" as used in this specification is intended to mean any form of phosphate solubilizing microorganism, fungus cells, mycelium or spores, bacterial cells or bacterial spores, which is capable of propagating on or in the soil, including on or in the vicinity of plant roots when the conditions of temperature, moisture, etc., are favorable for fungal growth. The phosphate solubilizing microorganism is preferably prepared in the form of a stable spore.

Solid state production of Penicillium spores may be achieved by inoculating a solid medium such as a peat or vermiculite-based substrate, seeds or grains including, but not limited to, corn, soy, potato, oats, wheat, barley, or rice. The sterilized medium (achieved through autoclaving or irradiation) is inoculated with a spore suspension comprising in the range of from 1 x10²-1 x10⁷ colony forming units per milliliter (cfu/ml) of the appropriate Penicillium spp. and the moisture adjusted to 20 to 50%, depending on the substrate. The inoculated medium is incubated for 2 to 8 weeks at room temperature. The spores may also be produced by liquid fermentation (Cunningham et al., 1990. Can J Bot. 68:2270-2274). Liquid production may be achieved by cultivating the fungus in any suitable media, such as potato dextrose broth or sucrose yeast extract media, under appropriate pH and temperature conditions that may be determined in accordance with standard procedures in the art.

The resulting material may be used directly, or the spores may be harvested, concentrated by centrifugation, formulated, and then dried using air drying, freeze drying, or fluid bed drying techniques (Friesen, et a/., 2005, Appl. Microbiol. Biotechnol. 68:397-404) to produce a wettable powder. The wettable powder is then suspended in water, applied to the surface of seeds, and allowed to dry prior to planting. The wettable powder may be used in conjunction with other seed treatments, such as, but not limited to, chemical seed treatments, carriers (for example, talc, clay, kaolin, silica gel, kaolinite) or polymers (for example, methylcellulose, polyvinylpyrrolidone). Alternatively, a spore suspension of the appropriate Penicillium spp. may be applied to a suitable soil-compatible carrier (for example, peat-based powder or granule) to appropriate final moisture content. The material may be incubated at room temperature, typically for about 1 day to about 8 weeks, prior to use.

The amount of the at least one phosphate solubilizing microorganism varies depending on the type of seed or soil, the type of plant material, the amounts of the source of phosphorus and/or micronutrients present in the soil or added thereto, etc. A suitable amount can be found by simple trial and error experiments for each particular case. Normally, for Penicillium, for example, the application amount falls into the range of from 0.001 to 1 .0 Kg fungal spores and mycelium (fresh weight) per hectare, or 10²-10⁶ colony forming units (cfu) per seed (when coated seeds are used), or on a granular carrier applying between 1 x10⁶ and 1 x10^{1 1} colony forming units per hectare. The fungal cells in the form of e.g., spores and the carrier can be added to a seed row of the soil at the root level or can be used to coat seeds prior to planting.

Diazotrophs are bacteria and archaea that fix atmospheric nitrogen gas into a more usable form such as ammonia. Examples of diazotrophs include bacteria from the genera Rhizobium spp. (e.g., R. cellulosilyticum, R. daejeonense, R. etli, R. galegae, R. gallicum, R. giardinii, R.

In another embodiment, the diazotroph is B. japonicum. In another embodiment, the diazotroph is R leguminosarum. In another embodiment, the diazotroph is R meliloti. In another embodiment, the diazotroph is S. meliloti.

Mycorrhizal fungi form symbiotic associations with the roots of a vascular plant, and provide, e.g., absorptive capacity for water and mineral nutrients due to the comparatively large surface area of mycelium.

Mycorrhizal fungi include endomycorrhizal fungi (also called vesicular arbuscular mycorrhizae, VAMs, arbuscular mycorrhizae, or AMs), an ectomycorrhizal fungi, or a combination thereof. In one embodiment, the mycorrhizal fungi is an endomycorrhizae of the phylum Glomeromycota and genera Glomus and Gigaspora. In still a further embodiment, the endomycorrhizae is a strain of Glomus aggregatum, Glomus brasilianum, Glomus clarum, Glomus deserticola, Glomus etunicatum, Glomus fasciculatum, Glomus intraradices, Glomus monosporum, or Glomus mosseae, Gigaspora margarita, or a combination thereof.

Examples of mycorrhizal fungi include ectomycorrhizae of the phylum

Basidiomycota, Ascomycota, and Zygomycota. Other examples include a strain of Laccaria bicolor, Laccaria laccata, Pisolithus tinctorius,

Rhizopogon amylopogon, Rhizopogon fulvigleba, Rhizopogon luteolus, Rhizopogon villosuli, Scleroderma cepa, Scleroderma citrinum, or a combination thereof.

The mycorrhizal fungi include ecroid mycorrhizae, arbutoid

mycorrhizae, or monotropoid mycorrhizae. Arbuscular and

ectomycorrhizae form ericoid mycorrhiza with many plants belonging to the order Ericales, while some Ericales form arbutoid and monotropoid mycorrhizae. In some embodiments, the mycorrhiza can be an ericoid mycorrhiza, for example, of the phylum Ascomycota, such as

Hymenoscyphous ericae or Oidiodendron sp. In another embodiment, the mycorrhiza also can be an arbutoid mycorrhiza, for example, of the phylum Basidiomycota. In yet another embodiment, the mycorrhiza can be a monotripoid mycorrhiza, for example, of the phylum Basidiomycota. In still yet another embodiment, the mycorrhiza can be an orchid mycorrhiza, for example, of the genus Rhizoctonia.

In some embodiments, the agricultural compositions can comprise combinations of any of the above listed components. For example, the agricultural composition can comprise a salt complex of Structure A,

Structure B, Structure C, Product 19 or Product 20 and a combination of two different insecticides, a fungicide and any one or more of the above listed bacterial or fungal strains. In other embodiments, the agricultural composition can comprise a salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20 and chlorantraniliprole,

cyantraniliprole or a combination of chlorantraniliprole and cyantraniliprole and one or more of the ingredients in Table 1 of rows 1 , 2 or 3.

TABLE 1

The agricultural composition can be applied by such methods as drenching the growing medium including a propagating material with a solution or dispersion of the agricultural composition, mixing the agricultural composition with growing medium and planting a propagating material in the treated growing medium (e.g., nursery box treatments), or various methods of propagating material treatment whereby the

agricultural composition is applied to a propagating material before it is planted in a growing medium. For growing-medium drenches, the formulation needs to provide the

Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex, generally after dilution with water, in solution or as particles small enough to remain dispersed in the liquid. Water-dispersible or soluble powders, granules, tablets, emulsifiable concentrates, aqueous

suspension concentrates and the like are formulations suitable for aqueous drenches of growing media. Drenches are most satisfactory for treating growing media that have relatively high porosity, such as light soils or artificial growing medium comprising porous materials such as peat moss, perlite, vermiculite and the like. The drench liquid comprising the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex can also be added to a liquid growing medium (i.e. hydroponics), which causes the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex to become part of the liquid growing medium. One skilled the art will appreciate that the amount of Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex needed in the drench liquid for efficacy (i.e. biologically effective amount) will vary with several factors including, but not limited to, plant species, propagating material type and environmental conditions. The concentration of the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex in the drench liquid is generally between about 10^"3 M to 10^"12 M of the composition, more typically between about 10^"6 M to 10^"10 M. One skilled in the art can easily determine the biologically effective

concentration necessary for the desired level of efficacy.

For treating a growing medium, the Structure A, Structure B,

Structure C, Product 19 or Product 20 salt complex can also be applied by mixing it as a dry powder or granule formulation with the growing medium. Because this method of application does not require first dispersing or dissolving in water, the dry powder or granule formulations need not be highly dispersible or soluble. While in a nursery box the entire body of growing medium may be treated, in an agricultural field only the soil in the vicinity of the propagating material is typically treated for environmental and cost reasons. To minimize application effort and expense, a formulation comprising the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex is most efficiently applied concurrently with propagating material planting (e.g., seeding). For in-furrow application, the Structure A, Structure B, Structure C, Product 19 or Product 20

formulation (most conveniently a granule formulation) is applied directly behind the planter shoe. For T-band application, the Structure A,

Structure B, Structure C, Product 19 or Product 20 formulation is applied in a band over the row behind the planter shoe and behind or usually in front of the press wheel. One skilled the art will appreciate that the amount of the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex needed in the growing medium locus for efficacy (i.e. biologically effective amount) will vary with several factors including, but not limited to, plant species, propagating material type and environmental conditions. The concentration of the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex in the growing medium locus is generally between about 10^"3 M to 10^"12 M of the composition, more typically between about 10^"6 M to 10^"10 M. One skilled in the art can easily determine the biologically effective amount necessary for the desired level of efficacy.

A propagating material can be directly treated by soaking it in a solution or dispersion of Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex. Although this application method is useful for propagating materials of all types, treatment of large seeds (e.g., having a mean diameter of at least 3 mm) is more effective than treatment of small seeds for providing efficacy. Treatment of propagating materials such as tubers, bulbs, corms, rhizomes and stem and leaf cuttings can also provide effective treatment of the developing plant in addition to the propagating material. The formulations useful for growing-medium drenches are generally also useful for soaking treatments. The soaking medium comprises a nonphytotoxic liquid, generally water-based although it may contain nonphytotoxic amounts of other solvents such as methanol, ethanol, isopropanol, ethylene glycol, propylene glycol, propylene carbonate, benzyl alcohol, dibasic esters, acetone, methyl acetate, ethyl acetate, cyclohexanone, dimethylsulfoxide and /V-methylpyrrolidone, which may be useful for enhancing solubility of the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex and penetration into the propagating material. A surfactant can facilitate wetting of the propagating material and penetration of the Structure A, Structure B,

Structure C, Product 19 or Product 20 salt complex. One skilled the art will appreciate that the amount of Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex needed in the soaking medium for efficacy (i.e. biologically effective amount) will vary with several factors including, but not limited to, plant species, propagating material type and environmental conditions. The concentration of Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex in the soaking liquid is generally between about 10^"3 M to10^"12 M of the composition, more typically between about 10^"6 M to 10^"10 M. One skilled in the art can easily determine the biologically effective concentration necessary for the desired level of efficacy. The soaking time can vary from one minute to one day or even longer. Indeed, the propagating material can remain in the treatment liquid while it is germinating or sprouting (e.g., sprouting of rice seeds prior to direct seeding). As shoot and root emerge through the testa (seed coat), the shoot and root directly contact the solution comprising the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex. For treatment of sprouting seeds of large-seeded crops such as rice, treatment times of about 8 to 48 hours, e.g., about 24 hours, is typical. Shorter times are most useful for treating small seeds.

A propagating material can also be coated with a coating

composition comprising a biologically effective amount of a Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex. The coatings of the disclosure are capable of affecting a slow release of a

Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex by diffusion into the propagating material and surrounding medium. Coatings include dry dusts or powders adhering to the propagating material by action of an adhesive agent such as

methylcellulose or gum arabic. Coatings can also be prepared from suspension concentrates, water-dispersible powders or emulsions that are suspended in water, sprayed on the propagating material in a tumbling device and then dried. Structure A, Structure B, Structure C, Product 19 or Product 20 salt complexes that are dissolved in the solvent can be sprayed on the tumbling propagating material and the solvent then evaporated. Such compositions can include ingredients promoting adhesion of the coating to the propagating material. The compositions may also contain surfactants promoting wetting of the propagating material. Solvents used must not be phytotoxic to the propagating material; generally water is used, but other volatile solvents with low phytotoxicity such as methanol, ethanol, methyl acetate, ethyl acetate, acetone, etc. may be employed alone or in combination. Volatile solvents are those with a normal boiling point less than about 100 °C. Drying must be conducted in a way not to injure the propagating material or induce premature germination or sprouting.

The thickness of coatings can vary from adhering dusts to thin films to pellet layers about 0.5 to 5 mm thick. Propagating material coatings of this disclosure can comprise more than one adhering layer, only one of which need comprise a Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex. Generally pellets are most satisfactory for small seeds, because their ability to provide a biologically effective amount of a Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex is not limited by the surface area of the seed, and pelleting small seeds also facilitates seed transfer and planting operations. Because of their larger size and surface area, large seeds and bulbs, tubers, corms and rhizomes and their viable cuttings are generally not pelleted, but instead coated with powders or thin films.

Propagating materials contacted with the salt complex of Structure A,

Structure B, Structure C, Product 19 or Product 20 in accordance to this disclosure include seeds. Suitable seeds include seeds of wheat, durum wheat, barley, oat, rye, maize (corn), sorghum, rice, wild rice, cotton, flax, sunflower, soybean, garden bean, lima bean, broad bean, garden pea, peanut, alfalfa, beet, garden lettuce, rapeseed, cole crop, turnip, leaf mustard, black mustard, tomato, potato, pepper, eggplant, tobacco, cucumber, muskmelon, watermelon, squash, carrot, zinnia, cosmos, chrysanthemum, sweet scabious, snapdragon, gerbera, babys-breath, statice, blazing star, lisianthus, yarrow, marigold, pansy, impatiens, petunia, geranium and coleus. Of note are seeds of cotton, maize (corn), soybean and rice. Propagating materials contacted with salt complexes of Structure A, Structure B, Structure C, Product 19 or Product 20 in accordance to this disclosure also include, for example, rhizomes, tubers, bulbs or corms, or viable divisions thereof. Suitable rhizomes, tubers, bulbs and corms, or viable divisions thereof include those of potato, sweet potato, yam, garden onion, tulip, gladiolus, lily, narcissus, dahlia, iris, crocus, anemone, hyacinth, grape-hyacinth, freesia, ornamental onion, wood-sorrel, squill, cyclamen, glory-of-the-snow, striped squill, calla lily, gloxinia and tuberous begonia. Of note are rhizomes, tubers, bulbs and corms, or viable division thereof of potato, sweet potato, garden onion, tulip, daffodil, crocus and hyacinth. Propagating materials contacted with salt complexes of Structure A, Structure B, Structure C, Product 19 or Product 20 in accordance to this disclosure also include stems and leaf cuttings.

In some embodiments, a propagating material is contacted with a coating composition comprising the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex and a film former or adhesive agent. Coating compositions which comprise a biologically effective amount of a salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20 and a film former or adhesive agent, can further comprise an effective amount of at least one of the previously mentioned biologically active compounds or agents. Of note are compositions comprising (in addition to the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex and the film former or adhesive agent)

arthropodicides of the group pyrethroids, such as cypermethrin, cyhalothrin, cyfluthrin and beta-cyfluthrin, esfenvalerate, fenvalerate and tralomethrin; carbamates such as fenothicarb, methomyl, oxamyl and thiodicarb; neonicotinoids such as clothianidin, imidacloprid and thiacloprid; neuronal sodium channel blockers such as indoxacarb;

insecticidal macrocyclic lactones such as spinosad, abamectin, avermectin and emamectin; γ-aminobutyric acid (GABA) antagonists such as endosulfan, ethiprole and fipronil; insecticidal ureas such as flufenoxuron and triflumuron; and juvenile hormone mimics such as diofenolan and pyriproxyfen.

Generally, the coating composition may further comprise formulation aids such as a dispersant, a surfactant, a carrier and optionally an antifoam agent and a dye. One skilled the art will appreciate that the amount of the Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex needed for efficacy (i.e. biologically effective amount) will vary with several factors including, but not limited to, plant species, propagating material type and environmental conditions. The coating needs to not inhibit germination or sprouting of the propagating material.

The film former or adhesive agent component of the propagating material coating can be composed of an adhesive polymer that may be natural or synthetic and is without phytotoxic effect on the propagating material to be coated. The film former or adhesive agent may be selected from polyvinyl acetates, polyvinyl acetate copolymers, hydrolyzed polyvinyl acetates, polyvinylpyrrolidone-vinyl acetate copolymer, polyvinyl alcohols, polyvinyl alcohol copolymers, polyvinyl methyl ether, polyvinyl methyl ether-maleic anhydride copolymer, waxes, latex polymers, celluloses including ethylcelluloses and methylcelluloses, hydroxymethylcelluloses, hydroxypropylcellulose, hydroxymethylpropylcelluloses, polyvinyl- pyrrolidones, alginates, dextrins, malto-dextrins, polysaccharides, fats, oils, proteins, karaya gum, jaguar gum, tragacanth gum, polysaccharide gums, mucilage, gum arabics, shellacs, vinylidene chloride polymers and copolymers, soybean-based protein polymers and copolymers,

lignosulfonates, acrylic copolymers, starches, polyvinylacrylates, zeins, gelatin, carboxymethylcellulose, chitosan, polyethylene oxide, acrylimide polymers and copolymers, polyhydroxyethyl acrylate, methylacrylimide monomers, alginate, ethylcellulose, polychloroprene and syrups or mixtures thereof. In some embodiments, film formers and adhesive agents include polymers and copolymers of for example, vinyl acetate, polyvinylpyrrolidone-vinyl acetate copolymer and water-soluble waxes. In other embodiments, the film formers and adhesive agents can be polyvinylpyrrolidone-vinyl acetate copolymers and/or water-soluble waxes. The above-identified polymers include those known in the art and for example some are identified as AGRIMER^® VA 6 (Vinylpyrrolidone/vinyl acetate copolymers available from Ashland, Inc., Covington, KY) and LICOWAX^® KST (an ester of montanic acids with multifunctional alcohols available from Clariant International Ltd., Muttenz, Switzerland). The amount of film former or adhesive agent in the formulation is generally in the range of about 0.001 to 100% of the weight of the propagating material. For large seeds the amount of film former or adhesive agent is typically in the range of about 0.05 to 5% of the seed weight; for small seeds the amount is typically in the range of about 1 to 100%, but can be greater than 100% of seed weight in pelleting. For other propagating materials the amount of film former or adhesive agent is typically in the range of 0.001 to 2% of the propagating material weight.

Materials known as formulation aids may also be used in propagating material treatment coatings of the disclosure and are well known to those skilled in the art. Formulation aids assist in the production or process of propagating material treatment and include, but are not limited, to dispersants, surfactants, carriers, antifoams and dyes. Useful dispersants can include highly water-soluble anionic surfactants like

BORRESPERSE™ CA (a spray dried calcium lignosulphonate available from Borregaard Deutschland GmbH, Karlsruhe, Germany), MORWET^® D425 (naphthalene sulfonate available from AkzoNobel, Amsterdam, Netherlands) and the like. Useful surfactants can include highly water- soluble nonionic surfactants like PLURONIC^® F108 (a difunctional block copolymer surfactant available from BASF, Florham Park, NJ), BRIJ^® 78 (polyethylene glycol octadecyl ether available from Sigma-Aldrich, St. Louis. MO) and the like. Useful carriers can include liquids like water and oils which are water-soluble such as alcohols. Useful carriers can also include fillers like woodflours, clays, activated carbon, diatomaceous earth, fine-grain inorganic solids, calcium carbonate and the like. Clays and inorganic solids which may be used include calcium bentonite, kaolin, china clay, talc, perlite, mica, vermiculite, silicas, quartz powder, montmorillonite and mixtures thereof. Antifoam agents can include water dispersible liquids comprising polyorganic siloxanes like RHODORSIL® 416 (mixture of silicone-polyether block copolymer and free polyether available from Rhodia Inc., Cranbury, NJ). Dyes can include water dispersible liquid colorant compositions like PRO-IZED® Colorant Red (liquid seed colorant available from Gustafson LLC, Piano, TX). One skilled in the art will appreciate that this is a non-exhaustive list of formulation aids and that other recognized materials may be used depending on the propagating material to be coated and the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20 used in the coating. Suitable examples of formulation aids include those listed herein and those listed in McCutcheon's 2001, Volume 2: Functional Materials, published by MC Publishing Company. The amount of formulation aids used may vary, but generally the weight of the

components will be in the range of about 0.001 to 10000% of the propagating material weight, with the percentages above 100% being mainly used for pelleting small seed. For nonpelleted seed generally the amount of formulating aids is about 0.01 to 45% of the seed weight and typically about 0.1 to 15% of the seed weight. For propagating materials other than seeds, the amount of formulation aids generally is about 0.001 to 10% of the propagating material weight.

Conventional means of applying seed coatings may be used to carry out the coating of the disclosure. Dusts or powders may be applied by tumbling the propagating material with a formulation comprising a

Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex and an adhesive agent to cause the dust or powder to adhere to the propagating material and not fall off during packaging or

transportation. Dusts or powders can also be applied by adding the dust or powder directly to the tumbling bed of propagating materials, followed by spraying a carrier liquid onto the seed and drying. Dusts and powders comprising a Structure A, Structure B, Structure C, Product 19 or Product

20 salt complex can also be applied by treating (e.g., dipping) at least a portion of the propagating material with a solvent such as water, optionally comprising a adhesive agent, and dipping the treated portion into a supply of the dry dust or powder. This method can be particularly useful for coating stem cuttings. Propagating materials can also be dipped into compositions comprising Structure A, Structure B, Structure C, Product 19 or Product 20 salt formulations of wetted powders, solutions,

suspoemulsions, emulfiable concentrates and emulsions in water, and then dried or directly planted in the growing medium. Propagating materials such as bulbs, tubers, corms and rhizomes typically need only a single coating layer to provide a biologically effective amount of a

Structure A, Structure B, Structure C, Product 19 or Product 20 salt complex.

Propagating materials may also be coated by spraying a suspension concentrate directly into a tumbling bed of propagating materials and then drying the propagating materials. Alternatively, other formulation types like wetted powders, solutions, suspoemulsions, emulsifiable concentrates and emulsions in water may be sprayed on the propagating materials. This process is particularly useful for applying film coatings to seeds. Various coating machines and processes are available to one skilled in the art. Suitable processes include those listed in P. Kosters et al., Seed

Treatment: Progress and Prospects, 1994 BCPC Monograph No. 57 and the references listed therein. Three well-known techniques include the use of drum coaters, fluidized bed techniques and spouted beds.

Propagating materials such as seeds may be presized prior to coating. After coating the propagating materials are dried and then optionally sized by transfer to a sizing machine. These machines are known in the art for example, as a typical machine used when sizing maize (corn) seed in the industry.

For coating seed, the seed and coating material are mixed in any variety of conventional seed coating apparatus. The rate of rolling and coating application depends upon the seed. For large oblong seeds such as those of cotton, a satisfactory seed coating apparatus comprises a rotating type pan with lifting vanes turned at sufficient rpm to maintain a rolling action of the seed, facilitating uniform coverage. For seed coating formulations applied as liquids, the seed coating must be applied over sufficient time to allow drying to minimize clumping of the seed. Using forced air or heated forced air can facilitate an increased rate of

application. One skilled in the art will also recognize that this process may be a batch or continuous process. As the name implies, a continuous process allows the seeds to flow continuously throughout the product run. New seeds enter the pan in a steady stream to replace coated seeds exiting the pan.

The seed coating process of the present disclosure is not limited to thin film coating and may also include seed pelleting. The pelleting process typically increases the seed weight from 2 to 100 times and can be used to also improve the shape of the seed for use in mechanical seeders. Pelleting compositions generally contain a solid diluent, which is typically an insoluble particulate material, such as clay, ground limestone, powdered silica, etc., to provide bulk in addition to a binder such as an artificial polymer (e.g., polyvinyl alcohol, hydrolyzed polyvinyl acetates, polyvinyl methyl ether, polyvinyl methyl ether-maleic anhydride copolymer, and polyvinyhpyrrolidinone) or natural polymer (e.g., alginates, karaya gum, jaguar gum, tragacanth gum, polysaccharide gum, mucilage). After sufficient layers have been built up, the coat is dried and the pellets graded. A method for producing pellets is described in Agrow, The Seed Treatment Market, Chapter 3, PJB Publications Ltd., 1994.

Seed varieties and seeds with specific transgenic traits may be tested to determine which seed treatment options and application rates may complement such varieties and transgenic traits in order to increase rate of germination, increase rate of seedling emergence, increase rate of radicle growth, increase rate of early growth, increase pest control, increase disease control, increase plant height, increase vigor, increase resistance to abiotic environmental stress, and increase biomass and/or yield. Further, the good root establishment and early emergence that results from the proper use of the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20 seed treatment may result in more efficient nitrogen use, a better ability to withstand drought and an overall increase in yield potential of a variety or varieties containing a certain trait when combined with a seed treatment containing the salt complexes of Structure A, Structure B, Structure C, Product 19 or Product 20.

In another embodiment of the disclosure, the agricultural composition is a foliar formulation. Such formulations will generally include at least one additional component selected from the group consisting of surfactants, solid diluents and liquid diluents, which serve as a carrier. The formulation ingredients are selected to be consistent with the physical properties of the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20, mode of application and

environmental factors such as soil type, moisture and temperature.

Useful foliar formulations include both liquid and solid formulations. Liquid formulations include solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions and/or

suspoemulsions) and the like, which optionally can be thickened into gels. The general types of aqueous liquid formulations are soluble concentrate, suspension concentrate, capsule suspension, concentrated emulsion, microemulsion and suspoemulsion. The general types of nonaqueous liquid formulations are emulsifiable concentrate, microemulsifiable concentrate, dispersible concentrate and oil dispersion.

The general types of solid formulations are dusts, powders, granules, pellets, prills, pastilles, tablets, filled films (including seed coatings) and the like, which can be water-dispersible ("wettable") or water-soluble. The salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20 can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation can be encapsulated (or "overcoated"). Encapsulation can control or delay release of the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20. An emulsifiable granule combines the advantages of both an emulsifiable concentrate formulation and a dry granular formulation.

High-strength compositions are primarily used as intermediates for further formulation.

Sprayable formulations are typically extended in a suitable medium before spraying. Such liquid and solid formulations are formulated to be readily diluted in the spray medium, usually water. Spray volumes can range from about one to several thousand liters per hectare, but more typically are in the range from about ten to several hundred liters per hectare. Sprayable formulations can be tank mixed with water or another suitable medium for foliar treatment by aerial or ground application, or for application to the growing medium of the plant. Liquid and dry

formulations can be metered directly into drip irrigation systems or metered into the furrow during planting. Liquid and solid formulations can be applied onto seeds of crops and other desirable vegetation as seed treatments before planting to protect developing roots and other subterranean plant parts and/or foliage through systemic uptake. Effective foliar formulations will typically contain from about 10^"3 M to 10^"12 M of the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20. In another embodiment, formulations contain from about 10^"6 M to 10^"10 M of the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20.

In another embodiment of the disclosure, the composition is applied to soil either prior to or following planting of plant propagating materials. Compositions can be applied as a soil drench of a liquid formulation, a granular formulation to the soil, a nursery box treatment or a dip of transplants. In some embodiments, the composition comprising the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20 is applied to the soil in the form of a soil drench liquid formulation. Other methods of contact include application of a salt or a composition of the disclosure by direct and residual sprays, aerial sprays, gels, seed coatings, microencapsulations, systemic uptake, foggers, fumigants, aerosols, dusts and many others. One embodiment of a method of contact is a dimensionally stable fertilizer granule, stick or tablet comprising a salt or composition of the disclosure. Effective soil formulations will typically contain from about 10^"3 M to 10^"12 M of the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20. In another embodiment, formulations contain from about 10^"6 M to 10^" ¹⁰ M of the salt complex of Structure A, Structure B, Structure C, Product 19 or Product 20. The methods of this disclosure is applicable to virtually all plant species, including monocots, dicots and gymnosperms.

Product 3

D-Glucosamine hydrochloride (Product 1 , 1 .0 kg) was suspended in methanol (5.0 L) and vigorously stirred. NaOH (184.8 g) was dissolved in minimum deionized water and added to the D-glucosamine/methanol (MeOH) suspension. The suspension was stirred for 15 min and the insoluble material (sodium chloride) was filtered off by vacuum filtration.

To the filtrate, phthalic anhydride (342 g) was added and the solution was stirred until most of the solid dissolved (about 30 min). This was then followed by addition of triethylamine (468 g) and stirring for 10 to 15 min. To the resulting clear solution, another portion of phthalic anhydride (342 g) was added and the mixture was allowed to stir overnight at room temperature. Product began to precipitate out after two hours.

The precipitated product was filtered and the residue was washed with minimum ice cold methanol so as to remove the yellow color from the product. The residue was then washed three times with acetonitrile, with enough solvent added to the filter to completely immerse the solid, and dried at room temperature under high vacuum. The weight of the white solid, Product 2, was 954 g. ¹ H-NMR (D₂O): 7.74-7.56 (phthalimido hydrogens), 5.42 (H-1 a), 4.94 (H-1 β), 4.17 and 4.01 (H-6), 3.27 (CH₂ of N-ethyl group), 1 .35 (CH₃ of N-ethyl group).

The Product 2 from above (1 .01 Kg, made from two batches) was placed in a 10 L 3-neck round bottom flask set up with an overhead electric stirrer, an N₂ inlet and an addition funnel. Acetic anhydride (3 L) and N,N-dimethylaminopyridine (1 .0 g) were added to the flask and stirred vigorously. Pyridine (2.8 L) was added slowly and the reaction mixture was stirred for 2 days at room temperature. The reaction mixture was quenched with ice-water (4 L) and the product was extracted with methylene chloride (CH2CI2). The organic layer was repeatedly washed with aqueous hydrochloric acid solution, and then with saturated sodium bicarbonate solution. The organic layer was dried over anhydrous magnesium sulfate, filtered, and concentrated to dryness. The product was recrystallized from hot ethanol . Weight of the recrystallized Product 3 was 701 g. ¹ H-NMR (CD₂CI₂) δ: 7.91 -7.80 (phthalimido hydrogens), 6.62 (H-1 ), 5.59 (H-3), 5.21 (H-4), 4.47 (H-2), 4.36 and 4.16 (H-6), 4.06 (H-5), 2,12, 2.06, 2.02, 1 .88 (acetyl methyl groups). Thus the above NMR chemical shift data verified the structure of Product 3, 2-deoxy-1 ,3,4,6- tetra-O-acetyl-2-phthalimido-D-glucopyranose.

Preparation of intermediate Product 4:

Product 3 Product 4

Product 3 (464 g) was dissolved in toluene and the solvent was evaporated. This was repeated and the remaining solid was placed on a high vacuum line overnight.

The dried solid was dissolved in minimum CH₂CI₂ (ca. 600 ml), and stirred well. To this, 4-methylbenzenethiol (181 g, 1 .45 mol, 1 .5 eq.) was added followed by the dropwise addition of boron trifluoride diethyl etherate (BF3-etherate; 165 g, 1 .16 mol, 1 .2 equivalent, over 180 min). The reaction mixture was stirred overnight. White crystals formed in the morning when stirring was stopped. The crystals were filtered, giving Product 4A. The filtrate was diluted with CH2CI2, washed sequentially with saturated NaHCO3 solution, water, then bicarbonate solution, and dried giving Product 4B. Products 4A and 4B were extensively washed with anhydrous methanol and dried under vacuum. Since the NMR spectrums of 4A and 4B products were identical, these two were combined (Product 4, 426.3 g).

¹ H-NMR (CD2CI2) δ: 7.96-7.80 (phthalimido hydrogens), 7.36 & 7.13 (S-aromatic hydrogens), 5.78 (H-3), 5.69 (H-1 ), 5.13 (H-4), 4.33 (H-2), 4.30 & 4.12 (H-6), 3.93 (H-5), 2.36 (S-Ph-Me group), 2.13, 2.04, 1 .85

(methyls of acetyl groups). Thus the NMR spectrum verified the structure of Product 4, as shown above.

Preparation of intermediate Product 5:

Product 4 Product 5 Product 4 (350 g) was suspended in nearly 4 L of dry methanol. To this, 35 ml of 0.5 M sodium methoxide solution was added and the solution immediately turned basic. The suspension was left stirring at room temperature overnight. The solid deposited was filtered and washed with dichloromethane, giving pure Product 5 (232 g). The filtrate was neutralized with sulfonic acid resin and concentrated to dryness. The dry solid was washed with CH₂Cl₂ and dried, giving impure Product 5 (43.8 g). ¹ H-NMR (CD3OD) of pure 5 δ: 7.87-7.76 (phthalimido hydrogens), 7.22 & 6.99 (S-aromatic hydrogens), 5.46 (H-1 ), 4.18 (H-2), 4.03 (H-3), 3.89 & 3.70 (H-6), 3.39 (H-5), 3.37 (H-4), 2.22 (S-Ph-Me group). Thus the NMR spectrum verified the structure of Product 5, as shown above.

Preparation of intermediate Product 6:

Product 5 Product 6

Product 5 (295 g; 638; mmol) was suspended in dry toluene (1 L) and evaporated under vacuum. This procedure was repeated once more to ensure the removal of methanol contaminant that is detrimental to the reaction. 265 grams total product was recovered. The residue after toluene evaporation was suspended in CH2CI2 (3 L) in a 3-neck flask fitted with an overhead stirrer and the suspension was stirred under dry nitrogen atmosphere. The flask was cooled in an ice bath and the following reagents were added: pyridine = 126 g, N,N-dimethylaminopyridine = 500 mg; and benzoyl chloride: 171 g (slowly added by means of an addition funnel in drops over 60 min). The reaction mixture was milky white, but began to clear when all of the benzoyl chloride was added. The reaction was allowed to stir for 18 h at room temperature. The reaction was diluted with CH2CI2 and was washed with water (2x), 1 M aqueous HCI (2x), then saturated NaHCO3 and dried with MgSO₄.

The crude product was recrystallized in 8 liters of hot EtOH, crystals were filtered, and washed in EtOH giving Crop 6A (225 g). The filtrate was concentrated to dryness giving Crop 6B (131 g). A second recrystallization of Crop 6A was done to give pure Product 6 (172g). The residue (40 g) from the filtrate of the second recrystallization had product 6 of purity greater than 95%, as determined by NMR. Crop 6B was not further processed as NMR analysis showed that it had a significant amount of undesired products and was therefore recycled back to Product 5.

1H-NMR (CD2CI2) δ: 8.14, 7.88, 7.69, 7.57, 7.41 (benzoate hydrogens), 7.80-7.72 (phthalimido hydrogens), 7.34 & 7.00 (S-aromatic hydrogens), 5.93 (H-3), 5.79 (H-1 ), 4.77 & 3.99 (H-6), 4.47 (H-2), 4.03- 3.99 (H-5), 3.91 (H-4), 3.25 (OH), 2.31 (S-Ph-Me group). Thus the NMR spectrum verified the structure of Product 6, as shown above.

Preparation of Monomer A

Product 6 Monomer A Product 6 (171 .9 g; 275.6 mmol) was dissolved in minimum methylene chloride (350 mL) containing collidine (41 .7 g; 344.5 mmol; 1 .25 eq.). t-BDMS-Triflate (80. Og; 303.1 mmol; 1 .1 eq.) was added drop-wise by addition funnel over 50 minutes. The reaction mixture was allowed to stir overnight. The reaction mixture was diluted with methylene chloride and washed sequentially with ice-cold water, 0.5 M aqueous HCL (ice cold), then aqueous saturated NaHCO3. It was then dried with MgSO₄, filtered and concentrated to give Monomer A as a white solid (207 g). The product was dissolved in dry toluene and concentrated to dryness before use in a glycosylation reaction. The 207 g of Monomer A product recovered was essentially equal to the theoretical yield, calculated to be 203.4 g.

H-NMR (CD₂CI₂) δ: 8.16 - 7.41 (benzoate hydrogens, phthalimido hydrogens), 7.30 & 6.95 (S-aromatic hydrogens), 5.97 (H-3), 5.82 (H-1 ), 4.89 & 4.49 (H-6), 4.40 (H-2), 4.14 (H-4), 4.01 (H-5), 2.30 (S-Ph-Me group), 0.80 (t-butyl group on silicon), 0.09& -0.16 (methyl groups of silicon). Thus the NMR spectrum verified the structure of Monomer A, as shown above.

Preparation of intermediate Product 7:

Product 3 Product 7 To ensure that the starting glycoside was free of EtOH traces, Product 3 (60.0 g; 126 mmol) was dissolved in toluene and evaporated. It was then dissolved in anhydrous CH₂CI₂ (500 ml) containing MeOH (6.5 g;

202 mmol; 1 .6 eq.). Tin tetrachloride (SnCI₄; 18.4 g; 70.5 mmol; 0.56 eq.) was diluted with CH2CI2 (25 ml) and added dropwise. The reaction mixture was poured over ice water and shaken well. This was repeated once more and then the organic layer was washed twice with aqueous saturated NaHCO3, dried with MgSO^ filtered, and concentrated. The crude product was recrystallized from hot EtOH, giving crystals of product 7(43.1 g). The 49.8 g crude yield of Product 7 was 88% of the theoretical yield, calculated to be 56.6 g, while the recrystallized Product 7 yield of 43.1 g was 76%.

¹H-NMR (CD₂CI₂) δ: 7.86-7.74 (phthalimido hydrogens), 5.78 (H-3), 5.31 (H-1 ), 5.18 (H-4), 4.31 (H-2), 4.34 & 4.20 (H-6), 3.88 (H-5), 2.20, 2.03, 1 .86 (methyls of acetyl groups). Thus the NMR spectrum verified the structure of Product 7, as shown above.

Preparation of intermediate Product 8:

Product 7 Product 8

Product 7 (141 .0 g; 314 mmol) was suspended in MeOH (1000 ml) and NaOMe (0.5 M, 10 ml) was added. The methyl glycoside Product 7 did not readily dissolve in MeOH. The solution was tested to ensure basicity. The reaction was stirred overnight. The solution became clear. Examination of the reaction mixture by TLC (EtOAc-hexane-EtOH;

10:20:1 ) indicated the disappearance of the starting material and the formation of a polar product (near the origin). The solution was neutralized with sulfonic acid resin, filtered, and concentrated to dryness. Weight of the residue, called Product 8, was 105.3 g, which probably includes some MeOH.

The crude yield of 105.3 g of Product 8 was essentially equal to the theoretical yield, calculated to be 101 .3 g. ¹H-NMR (CD₃OD) δ: 7.85-7.80 (phthalimido hydrogens), 5.07 (H-1 ), 4.21 (H-2), 3.94 (H-3), 3.92 & 3.74 (H-6), 3.40 (H-5), 3.40 (OCH₃), 3.38 (H-4). Thus the NMR spectrum verified the structure of Product 8, as shown above.

Preparation of Monomer B

Product 8 Monomer B

Product 8 (crude; 105.3), after being evaporated with toluene-DMF, was suspended in CH₂CI₂ (500 ml). Pyridine (61 .8 g; 782 mmol; 2.5 eq.) was added first, followed by the drop-wise addition of benzoyl chloride (88 g; 626 mmol; 2.0 eq.) to the mixture. The reaction mixture was allowed to stir at room temperature for 24 h. It was then diluted with CH₂CI₂ and washed sequentially with H₂O,1 M HCI (2X), then aqueous saturated sodium bicarbonate solution, dried with MgSO^ filtered, and concentrated.

The product was purified by chromatography on silica gel, using 3:8 EtOAc-hexane as the eluant. The weight of the purified product was 1 16.1 g. The product was about 90% pure as determined by NMR. A portion (21 .1 g) of this product was crystallized from diethylether-hexane to obtain pure crystalline material (13.8 g) of Monomer B. ¹H-NMR (CD₂CI₂) δ: 8.15, 7.92, 7.67, 7.56, 7.42 (benzoate hydrogens), 7.83-7.74 (phthalimido hydrogens), 5.93 (H-3), 5.40 (H-1 ), 4.82 & 4.72 (H-6), 4.43 (H-2), 4.03-3.92 (H-5, H-4), 3.50 (OCH₃), 3.33 (OH). Thus the NMR spectrum verified the structure of monomer B, as shown above. Example 4

Synthesis of Derivatized Glucosamine Disaccharide

Structural Characterization of Oligoglucosamine Derivatives:

The structures of the coupled products described below were confirmed by proton NMR and mass spectrometry as follows. The chemical shifts of hydrogens H-3 and H-1 of the phthalimido glucosamine unit appeared in proton NMR spectrum at chemical shifts between 5 and 6.5 ppm. The hydrogen H-3 appeared as a doublet of a doublet with a coupling constant of about 8-10 Hz. By counting the number of these hydrogen signals, the length of the oligoglucosamine can easily be determined, for the

disaccharide to the pentasaccharide. For oligoglucosamine derivatives of 6 and above, the signals for these hydrogens started to overlap. However, a sufficient number of these signals could be identified to confirm the structure. A similar observation was seen for the anomeric hydrogens, which appeared as a doublet with a coupling constant of about 8-8.5 Hz, thereby confirming the β-glycosidic configuration. Furthermore, the chemical shift of H-4 in the terminal glucosamine unit appeared around 3.5 ppm, when the corresponding carbon carried a hydroxyl group. This was shifted to 3.7 ppm upon glycosylation at this site. Thus, H-4 could be used as a reporter group for establishing the success of the glycosylation reaction. Further proof of structure was obtained by MALDI and

electrospray mass spectral data of the product, which are indicated for each compound.

Synthesis of Dimer Product 9

Monomer A Monomer B Product 9

Monomer A (80.6 g, 109.3 mmol, 1 .2 eq.) and Monomer B (48.4 g, 91 .1 mmol), both previously evaporated with toluene once, were dissolved in CH₂CI₂ (150 ml_) in a 3-necked, 500 ml flask. 4A Molecular sieve was added (5 g). The mixture was cooled to -60° C under nitrogen atmosphere with vigorous stirring. After 10 min, N-lodosuccinimide (NIS; 44.3 g; 196.7 mmol; 2.2 eq.) was added as a dry powder, followed by the dropwise addition of a solution of triflic acid (TfOH; 13.7 g, 91 .1 mmol, 1 .0 eq.) and methyltriflate (14.9 g, 54.8 mmol, 1 .0 eq.) in CH₂CI₂. The reaction mixture was left at -55° C for an additional 4 hr. An additional 100 ml of the triflic acid/methyltriflate solution was added to the reaction mixture dropwise to reduce of the viscosity. The reaction mixture was filtered cold over a celite pad into a filter flask containing 1 :1 saturated sodium thiosulfate-sodium bicarbonate solution that was stirred thoroughly during filtration. The flask and residue on the filter were rinsed with CH₂CI₂ and the combined filtrate was worked up as follows.

The filtrate was poured into a separatory funnel. The contents were thoroughly mixed, the aqueous solution separated, and the organic layer washed one more time with saturated aqueous sodium thiosulfate solution, followed by water, and aqueous saturated sodium bicarbonate solution. The solution was then dried with magnesium sulfate, filtered and

concentrated. Weight of the crude product was 1 1 1 .1 g. Analytically pure sample was prepared by subjecting the crude product to separation by silica gel chromatography, using ethyl acetate-hexane (3:8 v/v) as eluant. 1 H-NMR (CD₂CI₂) δ: 8.17 - 7.19 (phthalimido and benzoate hydrogens), 6.1 1 and 5.76 (2 x H-3), 5.74 and 5.31 (2 x H-1 ), 4.36 and 4.32 (2 x H-2), 4.32 and 3.93 (2 x H-4), 3.90 and 3.53 (2 x H-5), 4.65, 4.38, 4.12, and 3.63 (4 x H-6), 3.38 (OCH₃), 0.68 (t-butyl), -0.12, -0.40 (2 x CH₃). Mass spec: M. wt. Calc. 1 144.37; Obs. M+Na = 1 167.5. Thus the NMR spectrum verified the structure of Product 9, as shown above. The crude product as such was used in the next step, where complete removal of the tBDMS was accomplished.

Preparation of Intermediate Product 10:

Product 9 Product 10

Product 9 (1 1 1 .1 g) was dissolved in THF (350 ml). To this solution, a 1 M solution of acetic acid (1 10 ml) and a 1 M solution of n-tetrabutylammonium fluoride in THF (1 10 ml) were added and the reaction mixture was stirred at room temperature for 3 days. Completion of the reaction was ascertained by TLC using EtOAC-HexEtOH (4:8:1 ) as a solvent, which indicated that the reaction was complete. The solvent of the reaction was evaporated on high vacuum (without heat) and the residue was dissolved in CH2CI2, washed sequentially with water, 1 M aqueous HCI, 10% sodium thiosulfate aqueous solution, and finally, with saturated aqueous NaHCO₃. The solution was then dried with MgSO₄, filtered and concentrated. The resulting solid was treated with diethyl ether which resulted in a gluey material. The supernatant was filtered and the gluey material was repeatedly washed with diethyl ether. To the filtrate, hexane was added to precipitate any ether soluble product and this was filtered (Fraction B, 5.9 g). The final filtrate from ether-hexane was concentrated to dryness (Fraction C).

The NMR spectrum indicated that Fraction B product had about 5% silicon impurity (peak around 0 ppm) along with the major desired disaccharide. Fraction A was contaminated about 10% with tBDMS impurities and a tetrabutylammonium derivative. Therefore, Fraction A was resuspended in 600 ml of ether, mixed for about 10 minutes, filtered and the process was repeated once more (weight of the solid recovered was 77.3 g). This solid was purified once more by dissolving the product in EtOAc and precipitating the product with the aid of hexane (weight of the product recovered was 71 .7 g). The filtrates were combined, hexane was added to precipitate the remaining product and additional 10.8 g of the product was recovered. ¹ H-NMR (CD₂CI₂) δ: 8.12 - 7.14 (phthalimido and benzoate hydrogens), 6.14 and 5.73 (2 x H-3), 5.72 and 5.34 (2 x H- 1 ), 4.37 and 4.34 (2 x H-2), 4.10 and 3.69 (2 x H-4), 3.97 and 3.44 (2 x H- 5), 4.66, 4.18, 4.12- 4.06 (4 x H-6), 3.38 (OCH₃), 3.35 (OH). Mass spec: M. wt. Calc. 1030.98 ; Obs. M+Na = 1053.1 . Thus the NMR spectrum verified the structure of Product 10, as shown above.

Monomer A Product 10 Product 11

Monomer A (88.6 g; 120 mmol; 1 .5 eq.) and Product 10 (82.5 G; 80.0 mmol) were dissolved in CH2CI2 (100 ml) in a flask. Molecular sieve (4A, 5.0 g) was added. The flask was placed in a -55 °C water bath and stirred for 15 min. NIS (48.6 g; 216 mmol) was added as a powder to the cold solution, while maintaining vigorous stirring. A solution of methyl triflate (13.1 g; 80 mmol; 1 .0 eq.) and TfOH (12 g; 80 mmol; 1 .9 eq.), both dissolved together in CH₂CI₂ (5 ml), was added to the cold solution in drops by means of an addition funnel over 60 min. After 6 h at -60°C to -50°C, the reaction mixture was poured over saturated NaHCO3 and saturated sodium thiosulfate aqueous solution (1 :1 , 400 ml) contained in an Erlenmeyer flask and thoroughly stirred. Additional CH₂CI₂ (200 ml) was added and the contents were thoroughly mixed for 10 min, the aqueous solution separated, and the organic layer washed with 0.6% aqueous bleach solution, deionized water, and aqueous saturated CH₂CI₂ solution. The solution was then dried with MgSO4, filtered and

concentrated.

To remove the excess monomer impurity from the trisaccharide, the crude product was suspended in diethyl ether (600 ml), the solid thoroughly mixed and the supernatant filtered. This process was repeated three times and the residue finally dissolved in CH₂CI₂, then concentrated to dryness giving 93.5 g of product 1 1 . About 40% volume of hexane was added to the filtrate and the precipitated material filtered, redissolved in CH₂CI₂ and concentrated to dryness under vacuum to obtain an additional amount of Product 11 (26.0 g). ¹ H-NMR (CD₂CI₂) δ (only select hydrogen chemical shifts are reported): 8.13 - 7.12 (phthalimido and benzoate hydrogens), 6.03, 5.88, and 5.62 (3 x H-3), 5.64, 5.48, and 5.29 (3 x H-1 ), 3.77 (H-4 of the terminal glucosamine unit), 3.90 (H-5 of the terminal glucosamine unit), 4.63 (H-6 of the terminal glucosamine unit), 3.35 (OCHs), 0.64 (t-butyl), -0.18, -0.33 (2 x CH₃ of the silicon unit). Mass spec: Exact MW calc. 1643.49 ; Obs. M+Na = 1666.3. Thus the NMR spectrum verified the structure of Product 11 , as shown above. Example 7

Product 1 1 was dissolved in minimum THF (500 ml). To this solution, 1 M solution of acetic acid (150 ml) and a 1 M solution of n- tetrabutylammonium fluoride in THF (150 ml) were added and the reaction mixture was stirred at room temperature for 3 days. The reaction mixture was evaporated to dryness, the residue redissolved in CH₂CI₂, washed sequentially with deionized water, 1 M HCI, 1 % aqueous bleach solution (to remove the dark brown color), and saturated CH₂CI₂ solution, then concentrated to dryness.

In order to remove the nonpolar silicon and other impurities, the solid was dissolved in minimum ETOAc. Hexane was added in drops (the final solvent ratio EtOAc-hexane was 17:14). This resulted in a gluey material. The liquid was filtered and the gluey material redissolved in

EtOAc (200 ml) and precipitated with hexane (100 ml) as described above. Finally, diethyl ether was added to solidify the gluey material and the solid was filtered. The solid was redissolved in CH₂CI₂ and concentrated to dryness giving 81 .4 g of Product 12.

The filtrate EtOAc-Hexane-ether was concentrated to dryness. The residue was suspended in diethyl ether, shaken well and filtered. This process was repeated twice. Finally, the precipitate was dissolved in CH₂CI₂and concentrated to dryness to obtain additional product 12 (16.5 g). ¹ H-NMR (CD2CI2) δ (only select hydrogen chemical shifts are reported): 8.08 - 7.16 (phthalimido and benzoate hydrogens), 6.03, 5.92, and 5.59 (3 x H-3), 5.67, 5.48, and 5.29 (3 x H-1 ), 3.56 (H-4 of the terminal glucosamine unit), 3.91 (H-5 of the terminal glucosamine unit), 4.63 (H-6 of the terminal glucosamine unit), 3.35 (OCH₃), 3.01 (OH), 0.64. Mass spec: Exact m. wt. Calc. 1529.41 ; Obs. M+Na = 1553.4 . Thus the NMR spectrum verified the structure of product 12, as shown above.

Product 13

Step 1 : The derivatized disaccharide Product 10 (14.1 g, 13.7 mmol) was dissolved in anhydrous methanol (600 ml). Sodium methoxide solution (0.5 M, 7.5 ml) was added and the solution was stirred at room temperature for 24 h. Examination by TLC (EtOAc-hexane-EtOH =

20:20:1 and EtOAc-hexane-EtOH = 5:5:1 ) showed the disappearance of the starting material. The reaction was neutralized with sulfonic acid resin, filtered and concentrated to dryness. NMR of the product indicated incomplete de-O-benzoylation. The product was redissolved in anhydrous MeOH (600 ml), 0.5 M sodium methoxide solution (7 ml) was added and the solution was refluxed for 3 days. It was then neutralized with sulfonic acid resin, filtered and concentrated to dryness.

Step 2: The product from Step 1 was dissolved in 250 ml of n-butanol. Polystyrene-ethylenediamine resin (26.0 g) was added and the slurry was heated to 105° C with stirring for 24 h. It was then filtered, concentrated to dryness, and the resulting material was redissolved in water and washed with CH₂CI₂. The aqueous layer was concentrated to dryness.

Examination of the product by proton NMR (presence of signals between 7-8 ppm) showed incomplete phthalimide removal. The product was redissolved in n-butanol (100 ml) containing 10 g of freshly prepared MR- ethylenediamine resin and heated to 100° C for 16 h, filtered over a celite pad and concentrated to dryness. Weight of the product, designated Product 13, was 4.0 g. ¹ H-NMR (D₂O) δ: 4.48 and 4.33 (2 x H-1 ), 3.98, 3.95, 3.83, 3.76 (4 x H-6), 3.67, 3.54, 3.43, 3.40 (2 x H-3, 2 x H-4), 3.60 (OCH₃), 2.70 and 2.66 (2 x H-2). Mass spectral data (electrospray): m/e calc. 354.16 (100%); Obs. M+1 = 355.1 . Thus the NMR and MALDI spectra verified the structure of Product 13, as shown above.

Product 14

The trisaccharide Product 12 (6.1 g) was suspended in MeOH (300 ml), then NaOMe (0.5 M, 7 ml) was added and stirred at room temperature for 2 days. The mixture was then heated to 65° C for 24 h. Examination of the reaction mixture by proton NMR indicated that all benzoate groups had been removed. A white precipitate appeared in the reaction flask. The flask was cooled in an ice bath for 15 min and filtered. The filtrate was neutralized with acidic resin, and concentrated to dryness (Fraction B). The residue in the filter was washed with hot DMF and concentrated to dryness (Fraction A).

Fractions A and B were separately suspended in n-butanol (200 ml), treated with MR-ethylenediamine resin (20 g) and heated to 100° C for 24 h. The hot solution from Fraction A was filtered over a celite pad and washed with 1 :1 methanol-water. The combined filtrate was concentrated to dryness (Fraction C, 853 mg). Proton NMR of the product indicated it to be the desired triglucosamine Product 14. ¹ H-NMR (D₂O) δ: 4.54, 4.52, and 4.37 (3 x H-1 ), 4.01 , 3.98, 3.87, 3.80 (6 x H-6), 3.63 (OCHs), 2.78, 2.74, and 2.70 (3 x H-2). Mass spectral data (ESI): m/e calc. 515.23 (100%) ; Obs. M+Na = 516.2.

Similarly, the reaction mixture from Fraction B was filtered, washed and concentrated to dryness. The yellow solid was dissolved in water and the aqueous layer was extracted twice with CH₂CI₂to remove the byproduct methyl benzoate. Finally, the aqueous layer was concentrated to dryness, the residue redissolved in water, and lyophilized (Fraction E). NMR analysis of the Fraction E product indicated incomplete phthalimide removal. The solid was suspended in n-butanol (100 ml) and heated to 104° C. MR-Ethylenediamine resin (9 g) was added and the reaction was continued for two days. The hot reaction mixture was filtered over a Celite pad, washed with 1 :1 MeOH:water (30 ml), and then with water (2 x 15 ml). The combined filtrate was concentrated to dryness. The residue was dissolved in water and lyophilized (Fraction F). The NMR spectrum of Fraction F showed that though the major product was the desired triglucosamine Product 14, it was contaminated with some incompletely deprotected trisaccharide.

LiOH aqueous solution (5 ml_, 15 wt% in Dl-water) was added and the mixture was stirred at room temperature for about 4 h. The reaction mixture was concentrated under vacuum. The resulting residue was diluted with water (5 ml), acidified with 2N HCI to pH 1 -2 and extracted with diethyl ether (3 times, 20 ml/each). The combined organic extracts were washed with brine (15 ml) and water (15 ml), dried over anhydrous Na₂SO₄, filtered, and concentrated to give 0.47 g of the corresponding acid 17 quantitatively, which was used in next step without further purification.

d) Synthesis of A/-[(2E,1 1 Z)-octadeca-2,1 1 -dienoyl]glycine 18

Compound 17 (0.2 g, 1 .15 mmol) was dissolved in 1 :2 DMF/THF (total volume is 5 ml). To this solution, 4-N,N-dimethylaminopyridine (DMAP) (0.25g, 2.07 mmol), 1 -Ethyl-3-(3'-dimethylaminopropyl)carbodiimide hydrochloride (EDC) (0.40 g, 2.07 mmol), and Gly-O'Bu.HCI (0.23 g, 1 .38 mmol) were added and the reaction was stirred at room temperature overnight. After completion of the reaction, the mixture was pumped dry and washed with DI-H₂O three times (5 ml/each). The product was purified by column chromatography on silica gel to afford 220 mg of the

homogeneous product in 67% yield. The structure was characterized by ¹ H NMR: ¹ H NMR (500 MHz, CDCI₃): δ 6.85 (dt, J₁ = 15.3 Hz, J₂ = 7.0 Hz, 1 H), 5.92 (br, 1 H), 5.81 (d, J = 15.3 Hz, 1 H), 5.35-5.33 (m, 2H), 4.0 (d, J = 5.0 Hz, 2H), 2.19-2.14 (m, 2H), 2.02-1 .99 (m, 4H), 1 .47 (s, 9H), 1 .46-1 .40 (m, 2 H), 1 .33-1 .25 (m, 16H), 0.88 (t, J = 6.9 Hz, 3H).

All materials, with the exception of the seeds (corn or soybean) were sterilized before use.

Germination Assay for Examples 14, 16, 18, 19 and 22

An aqueous solution of the test compounds (25 ml_, 10^"7 M in Dl- water) was prepared for each set of five repeat experiments. A fungicide solution was added to each of the aqueous solutions of the test

compounds. Five Petri dishes and 100 seeds were used to test one composition. The seeds were inspected for uniformity and lack of cracks in the seed prior to use. A piece of filter paper was used to cover the inner side of each Petri dish to allow uniform distribution of the testing solution. Twenty seeds were placed on the filter paper area of one Petri dish. Each corn seed of example 14, 16, 18 and 22 was placed on the filter paper with the flat side of the corn seed facing upwards. The seeds were placed on the filter paper so that the seeds were not touching each other. 5 ml_ of the test compound solution was carefully poured in the Petri dish. Control experiments were set up the same way with 20 seeds and 5 ml_ of deionized water per dish without the use of salt complex. The lid was placed on the Petri dish and was sealed with Para-film. Five dishes with repeat experiments were stacked. Each stack of dishes was wrapped twice with aluminum foil to prevent the seeds receiving any light and the stacks were germinated in dark at the ambient laboratory conditions. The stacks containing the seeds were inspected at the time intervals indicated in each example. The number of germinated seeds was counted and the percent of germination on each dish was calculated. Radicle emergence was used as the germination indicator. At the end of the testing period, the dishes were placed unwrapped at room temperature for one day and the number of germinated seeds was counted to assure seeds were able to germinate and difference in germination yields were not caused by poor seed quality.

Cold Stress Germination Assay for Example 15

A seed coating composition was prepared comprising fungicide, insecticide, film forming binder, colorant, Product 19 (3 x 10^"7 M) and water. A control coating composition was also prepared using the identical ingredients, but excluding Product 19. Corn seeds were coated with the seed coating composition using spray treatment method. Five Petri dishes and 100 seeds were used to test each composition. Each corn seed was inspected for uniformity and lack of cracks in the seed prior to use. A piece of filter paper was used to cover the inner side of each Petri dish to allow uniform distribution of water. Twenty corn seeds were placed on the filter paper area of one Petri dish with the flat side of the corn seed facing upwards. The seeds were placed on the filter paper so that the corn seeds were not touching each other. 5 ml_ of water was added to each petri dish. The dishes were sealed and placed in an incubator set to 10°C. The dishes were examined twice per day at days 3, 4, 5 and 6 or until germination (radicle emergence) had reached 60-70%. During the observation period, one stack was removed from the incubator and observed for germination. The dishes were then rotated within the stack and placed back into the incubator before removing another treatment stack.

Cold Stress Germination Assay for Example 17

An aqueous solution of Product 20 (25 ml_, 10^"7 M in Dl-water) was prepared for each set of five repeat experiments. A fungicide solution was added to each of the aqueous solutions of the test compound. Five Petri dishes and 100 corn seeds were used to test one composition. The seeds were inspected for uniformity and lack of cracks in the seed prior to use. A piece of filter paper was used to cover the inner side of each Petri dish to allow uniform distribution of testing solution. Twenty seeds were placed on the filter paper area of one Petri dish. Each corn seed was placed on the filter paper with the flat side of the corn seed facing upwards. The seeds were placed on the filter paper so that the seeds were not touching each other. 5 mL of the test compound solution was carefully poured in the Petri dish. Control experiments were set up the same way with 20 seeds and 5 mL of deionized water per dish without Product 20. The dishes were sealed and placed in an incubator set to 10°C. The dishes were examined twice per day at days 3, 4, 5, 6, 7 and 8 or until

germination (radicle emergence) had reached 60-70%. During the observation period, one stack is removed from the incubator and observed for germination. The dishes were then rotated within the stack and placed back into the incubator before removing another treatment stack.

Cold Stress Germination Assay for Example 20

Seed coating compositions were prepared comprising fungicide, insecticide, film forming binder, colorant, Product 19 or 20 (3 x 10^"7 M) and water. A control coating composition was also prepared using the identical ingredients and amounts, but excluding Product 19 or 20. Soybean seeds were coated with the seed coating composition using spray treatment method. Five Petri dishes and 100 seeds were used to test each composition. Each seed was inspected for uniformity and lack of cracks in the seed prior to use. A piece of filter paper was used to cover the inner side of each Petri dish to allow uniform distribution of testing solution.

Twenty soybean seeds were placed on the filter paper area of one Petri dish. The seeds were placed on the filter paper so that the seeds were not touching each other. 5 mL of water was added to each petri dish. The dishes were sealed and placed in an incubator set to 10°C. The dishes were examined twice per day at days 3, 4, 5 and 6 or until germination (radicle emergence) had reached 60-70%. During the observation period, one stack is removed from the incubator and observed for germination. The dishes were then rotated within the stack and placed back into the incubator before removing another treatment stack.

Seed Germination Assay for Example 21

Soybean seed coating was performed with a Hege 1 1 liquid seed treater (Wintersteiger AG, Austria) using a standard seed coating protocol. The experimental coating premix was formulated to provide 10^"7 M Product 20 and standard commercial concentrations of a fungicide mixture. Control seeds were coated using the same insecticide/fungicide formulation and coating procedure without the addition of Product 20.

The germination assay utilized one flat per treatment, with each flat containing eight pots individually filled with METRO-MIX^® soil, available from Sun Gro, Agawam, Massachusetts. Three liters of water was added to each flat by removing the corner pot and pouring solution into the bottom of the flat. The soil was then allowed to absorb water from the bottom-up overnight. The following day, four soybean seeds were planted to a 1 " depth in each pot of moistened soil (32 seeds/flat/treatment). Each seed was separated from neighboring seeds by approximately 2".

Following planting, the flats were covered with dome covers and placed in an incubator maintained at 10°C. The domes were removed when the seeds began to germinate and maintained in a 10°C incubator for an additional three weeks. Once most of the plants had emerged, the flats were moved to a room temperature growth chamber. Percent emergence was determined 10, 13, 17 and 19 days following planting. Root length was determined 19 days following planting by carefully removing the plants from the soil and washing the roots prior to measurement.

For each of the examples, statistical analyses were performed by calculating the standard deviation of the five repetitions for each experiment. The data was deemed acceptable when the standard deviation was less than 10 percent. Experimental data for these above tests wherein the standard deviation was greater than 10 percent was not used.

Aqueous solutions of comparative Product 21 and comparative Product 22 did not have a statistically significant effect on germination percentage versus the control treatment. Example 23

Stock solutions of Product 20 were prepared as 1 millimolar solutions in DMSO and stored prior to use at 4°C. Germination was assessed using a commercial Pioneer corn hybrid. In this assay, 5 petri dishes and 100 seeds were used for each assay. Twenty corn seeds were randomly placed in each sterile petri dish lined with Whatman #1 paper disks. Test solutions of the Product 20 DMSO solutions were diluted with water to a concentration of 1 x 10^"7M with 2 percent by volume of fungicide added to prevent fungal growth. 5 ml of the test solution was added and the lid was placed on the dish. 5 replicate dishes were prepared for each trial. As control experiments, 100 seeds were tested using water only as the treatment and a second control was used wherein an aqueous solution of DMSO was used. Each stack of 5 dishes was secured with a rubber band and placed in a closed (light tight) cardboard box for the experiments at 10°C. For those tests at 24°C, stacks were individually wrapped in aluminum foil to exclude light and the dishes were placed in a growth chamber set to maintain the desired temperature.

Germination was assessed strictly as radical emergence at the time of observation. Counts of emerged radicles were converted to percentages and the data was analyzed using GraphPad PRISM® software, available from GraphPad, San Diego, California.

The effect of Product 20 composition on corn seeds at 24°C is shown in Table 13 wherein germination was assessed at 24 and 48 hours after the initiation of the experiment.

Corn Field Trials

The effect of Product 20 on the yield of corn was studied at 18 research sites in the United States using 5 different commercial hybrids.

A seed treatment formulation was prepared using commercially available film forming binder, fungicide and insecticide treatment and red pigment for the control, Control A. Composition 1 was prepared using the same formulation as Control A, but also added Product 20. Specifically, a 1 .7 μΜ solution of Product 20 was applied to corn seed at a dose of 0.7 fluid ounces per 80,000 seeds. Composition 2 was prepared using the same formulation as Composition 1 , but with an added standard biological component.

The corn seeds were planted in four row corn plots with 76.2 cm (30 inch) row spacings and a plot length of 5.3 meters (17.5 feet). At each research site, each treatment (seeds coated with Control A, Composition 1 and Composition 2) was replicated 4 times. Corn grain yield data

(bu/acre) was collected at harvest from the 2 center rows of each 4-row plot. Plots were managed by utilizing crop management practices common to each research site location.

When analyzed over all 18 locations, the Control A gave an average of 187.5 bushels of grain per acre. Composition 1 , containing Product 20, when analyzed over all 18 locations, gave an average of

191 .9 bushels of grain per acre. Composition 2 when analyzed over all 18 locations gave an average yield of 191 .8 bushels of grain per acre.

The effect of Product 20 with and without Bacillus amyloliquefaciens strain, 22CP1 on corn was studied during the growing season at 14 research sites in the United States using two corn hybrids. A 1 .7 μΜ solution of Product 20 was applied to corn seed at a dose 0.7 fl. oz. per 80,000 seeds along with standard seed treatment chemistries (Product 20). This same dose of Product 20 was combined with Bacillus

amyloliquefaciens strain, 22CP1 , and coated on seed with a final Bacillus dose of 1 x10⁶ CFU/seed along with standard seed treatment chemistries (Product 20+22CP1 ). Corn seed was also treated with standard seed treatment chemistries with 22CP1 alone (22CP1 ) and with standard seed treatment chemistries without the addition of any biological (control). At each of 14 geographical locations, all treatments were tested with two corn hybrids in six replicate plots each. Plots were designed as 4 rows with 30" spacing between rows and each row was 17.5' long. Plants were scored for early growth (scale of 1 -9) and stand count (plants/plot) at the vegetative state V2-V4 and final stand (plants/acre) and yield

(bushels/acre) was determined at full maturity of the plants.

An increase in early seedling vigor was detected in plants grown in the presence of Product 20 alone and Product 20+22CP compared to control and 22CP1 alone (p<0.05). There were no differences noted in early stand or final stand count. Final yield showed an increase of 1 .6 and 1 .4 bu/acre in the plants treated with Product 20 and Product 20+22CP1 , respectively, compared to the control treatment. The plants treated with Product 20+22CP1 showed a 2.4 bu/acre increase compared to those treated with 22CP1 alone.

Soybean Field Trials

The effect of Product 20 on the yield of soybeans was studied during the growing season at 20 research sites in the United States. A control soybean seed treatment formulation, Control C was prepared using a standard seed treatment formulation containing commercially available fungicide, insecticide, and surfactant. A second control formulation, Control B, was prepared using Control C and an added Rhizobia

inoculant. Composition 3 was prepared using Control C and added

Product 20. Specifically, a 1 .7 μΜ solution of Product 20 was applied to soybean seed at a dose of 0.35 fluid ounces per 140,000 seeds.

Composition 4 was prepared using Control B, and added Product 20. 25 .cCommercial soybean varieties were studied.

The soybeans were planted in four row plots with 76.2 cm (30 inch) row spacings and a plot length of 5.3 meters (17.5 feet). At each research site, each treatment (seeds coated with Control B, Control C, Composition 3 and Composition 4) was replicated 4 times. Soybean yield data

(bu/acre) was collected at harvest from the 2 center rows of each 4-row plot. Plots were managed by utilizing crop management practices common to each research site location. It should be noted that one research location was not harvested due to plot variability.

All seed treatments were composed of a first fungicide, a second fungicide and an insecticide applied with and without Product 20. An untreated check was also at each location.

When analyzed over 19 locations, the untreated check plots gave an average of 58.6 bushels per acre. Control B gave an average of 59.6 bushels per acre. Control C gave an average of 59.7 bushels per acre. Composition 3, containing Product 20, when analyzed over 19 locations, gave an average of 59.8 bushels per acre. Composition 4 when analyzed over 19 locations gave an average yield of 59.1 bushels per acre. The average yield for the trials containing Product 20 provided increased yield when compared to an untreated check plot. It should be noted that the results from one field location has not been included in the results due to plot variability issues that occurred at that location.

The effect of Product 20 on soybeans was studied during the 2013 and 2014 growing season. Product 20 was coated on two varieties of soybean seed. A 1 .7 μΜ solution of Product 20 was applied to soybean seed at a dose of 0.35 fluid ounces per 140,000 seeds (2013 trial) or 1 .26 fluid ounces per 140,000 seeds (2014 trial) along with standard seed treatment chemistries. Another treatment included the standard seed treatment chemistries without the addition of Product 20 (STD), and an additional treatment did not include any experimental or chemical seed treatments (Control). Seeds were planted at 20 different geographical locations in 2013 and 32 different geographical locations in 2014. The 2013 trial included four replications per location, while the 2014 trial included two replications per location. Row spacing for both the 2013 and 2014 trials was 30-inches at all locations and row length was between 15 and 17.5 feet depending on location. Early seedling vigor score (1 -9 scale with 1 = lowest; 9 = highest) and stand count (plants/acre) were recorded as well as yield (bushels/acre) at the conclusion of the trial.

Early seedling vigor was collected at 37 geographical locations over the course of two planting seasons. Plants grown in the presence of Product 20 had greater average seedling vigor scores compared to the Control treatment in each of the two seasons, and values that were similar to the STD treatment. The Product 20 seed treatment also resulted in greater average seedling vigor scores compared to the Control and STD treatments at averages of 90.9% and 38.7% of locations, respectively.

Stand count (plants/acre) was collected at the 20 geographical locations associated with the 2013 trial. Plants grown in the presence of Product 20 seed treatment had a greater average stand count compared to the Control treatment, and similar performance to the STD treatment. In addition, Product 20 increased stand relative to the Control treatment at 70% of locations and increased stand relative to the STD treatment at 55% of locations. Grain yield (bushels/acre) was collected at 51 geographical locations over the course of the two planting seasons. Plants grown in the presence of Product 20 seed treatment had greater yield compared to the Control treatment and similar performance to the STD treatment. Relative to the Control treatment, Product 20 increased yield at an average of 77.4% of locations, and increased yield relative to the STD treatment at an average of 37.2% of locations.

Potato Field Trial

Product 20 was tested on potato seeds in Canada using a standard seed treatment as a control and the standard seed treatment plus the addition of Product 20. Specifically, a 1 .7 μΜ solution of Product 20 was applied to potato seed at a dose of 0.7 fluid ounces per 100 pounds of seeds. Plots were managed by utilizing crop management practices common to potato growers. The percent emergence as a function of days after planting, the average plant height and the average plant width was measured at several intervals after emergence, the average plant count per 18.3 meter (60 feet) row, average tuber count in 10 kilograms of harvest, the percentage of "smalls" per treatment, the average percent ten ounce by treatment and the total yield per treatment was measured. The results are given in the Table 15.

TABLE 15

Soft Red Wheat Field Trial

Product 20 was tested on 2 varieties of soft red wheat at four locations in the North America versus untreated soft red wheat and a standard wheat seed control. Product 20 was added to the standard wheat seed treatment. Specifically, a 1 .7 μΜ solution of Product 20 was applied to wheat seed at a dose of 4.0 fluid ounces per 100 pounds of seed. The test plots measured 5.5 meters (18 feet) long with 15 to 18 centimeter (6 to 7 inch) row spacing. Two adapted varieties were tested per location and 6 replications per treatment per location were used. Data for the Wheat Stand percentage and early vigor is the average for two of the four locations. The yield data is available for all four locations. Early vigor is a qualitative assessment of the health of the early stage growth of the wheat plant and is assessed on a scale of 1 to 9.
