  • Water is generally the carrier of choice for the dilution of the concentrates.
  • Suitable solid carriers are, for example, talc, titanium dioxide, pyrophyllite clay, silica (fumed or precipated silica and optionally functionalised or treated, for instance silanised), attapulgite clay, kieselguhr, limestone, calcium carbonate, bentonite, calcium montomorillonite, cottonseed husks, wheatmeal, soybean flour, pumice, wood flour, ground walnut shells, lignin and similar materials, as described, for example, in the EPA CFR 180.1001. (c) & (d). Powdered or granulated fertilisers can also be used as solid carriers.
  • A large number of surface-active substances can advantageously be used both in solid and in liquid formulations, especially in those formulations which can be diluted with a carrier prior to use. Surface-active substances may be anionic, cationic, amphoteric, non-ionic or polymeric and they may be used as emulsifiying, wetting, dispersing or suspending agents or for other purposes. Typical surface-active substances include, for example, salts of alkyl sulfates, such as diethanolammonium lauryl sulfate; Sodium lauryl sulfate, salts of alkylarylsulfonates, such as calcium or sodium dodecylbenzenesulfonate; alkylphenol-alkylene oxide addition products, such as nonylphenol ethoxylates; alcohol-alkylene oxide addition products, such as tridecyl alcohol ethoxylate; soaps, such as sodium stearate; salts of alkylnaphthalenesulfonates, such as sodium dibutylnaphthalenesulfonate; dialkyl esters of sulfosuccinate salts, such as sodium di(2-ethylhexyl)sulfosuccinate; sorbitol esters, such as sorbitol oleate; quaternary amines, such as lauryl trimethylammonium chloride, polyethylene glycol esters of fatty acids, such as polyethylene glycol stearate; block copolymers of ethylene oxide and propylene oxide; and salts of mono- and di-alkyl phosphate esters; and also further substances described e.g. in “McCutcheon's Detergents and Emulsifiers Annual”, MC Publishing Corp., Ridgewood, N.J., 1981.
  • Further adjuvants which can usually be used in pesticidal formulations include crystallisation inhibitors, viscosity-modifying substances, suspending agents, dyes, anti-oxidants, foaming agents, light absorbers, mixing aids, anti-foams, complexing agents, neutralising or pH-modifying substances and buffers, corrosion-inhibitors, fragrances, wetting agents, absorption improvers, micronutrients, plasticisers, glidants, lubricants, dispersants, thickeners, anti-freezes, microbiocides, compatibility agents and solubilisers and also liquid and solid fertilisers.
  • The formulations may also comprise additional active substances, for example further herbicides, herbicide safeners, plant growth regulators, fungicides or insecticides.
  • The compositions according to the invention can additionally include an additive (commonly referred to as an adjuvant), comprising a mineral oil, an oil of vegetable or animal origin, alkyl esters of such oils or mixtures of such oils and oil derivatives. The amount of oil additive used in the composition according to the invention is generally from 0.01 to 10%, based on the spray mixture. For example, the oil additive can be added to the spray tank in the desired concentration after the spray mixture has been prepared. Preferred oil additives comprise mineral oils or an oil of vegetable origin, for example rapeseed oil, olive oil or sunflower oil, emulsifiable vegetable oil, such as AMIGO® (Loveland Products Inc.), alkyl esters of oils of vegetable origin, for example the methyl derivatives, or an oil of animal origin, such as fish oil or beef tallow. A preferred additive contains, for example, as active components essentially 80% by weight alkyl esters of fish oils and 15% by weight methylated rapeseed oil, and also 5% by weight of customary emulsifiers and pH modifiers. Especially preferred oil additives comprise alkyl esters of C8-C22 fatty acids, especially the methyl derivatives of C12-C18 fatty acids, for example the methyl esters of lauric acid, palmitic acid and oleic acid, being important. Those esters are known as methyl laurate (CAS-111-82-0), methyl palmitate (CAS-112-39-0) and methyl oleate (CAS-112-62-9). A preferred fatty acid methyl ester derivative is AGNIQUE ME 18 RD-F® (Cognis). Those and other oil derivatives are also known from the Compendium of Herbicide Adjuvants, 5th Edition, Southern Illinois University, 2000.
  • The application and action of the oil additives can be further improved by combining them with surface-active substances, such as non-ionic, anionic, cationic or amphoteric surfactants. Examples of suitable anionic, non-ionic, cationic or amphoteric surfactants are listed on pages 7 and 8 of WO97/34485. Preferred surface-active substances are anionic surfactants of the dodecylbenzylsulfonate type, especially the calcium salts thereof, and also non-ionic surfactants of the fatty alcohol ethoxylate type. Special preference is given to ethoxylated C12-C22 fatty alcohols having a degree of ethoxylation of from 5 to 40. Examples of commercially available surfactants are the Genapol types (Clariant). Also preferred are silicone surfactants, especially polyalkyl-oxide-modified heptamethyltrisiloxanes, which are commercially available e.g. as SILWET L-77®, and also perfluorinated surfactants. The concentration of surface-active substances in relation to the total additive is generally from 1 to 50% by weight. Examples of oil additives that consist of mixtures of oils or mineral oils or derivatives thereof with surfactants are TURBOCHARGE®, ADIGOR® (both (Syngenta Crop Protection AG), ACTIPRON® (BP Oil UK Limited), AGRI-DEX® (Helena Chemical Company).
  • The said surface-active substances may also be used in the formulations alone, that is to say without oil additives.
  • Furthermore, the addition of an organic solvent to the oil additive/surfactant mixture can contribute to a further enhancement of action. Suitable solvents are, for example, SOLVESSO® and AROMATIC® solvents (Exxon Corporation). The concentration of such solvents can be from 10 to 80% by weight of the total weight. Such oil additives, which may be in admixture with solvents, are described, for example, in U.S. Pat. No. 4,834,908. A commercially available oil additive disclosed therein is known by the name MERGE® (BASF). Further oil additives that are preferred according to the invention are SCORE® and ADIGOR® (both Syngenta Crop Protection AG).
  • In addition to the oil additives listed above, in order to enhance the activity of the compositions according to the invention it is also possible for formulations of alkylpyrrolidones, (e.g. AGRIMAX® from ISP) to be added to the spray mixture. Formulations of synthetic latices, such as, for example, polyacrylamide, polyvinyl compounds or poly-1-p-menthene (e.g. BOND®, COURIER® or EMERALD®) can also be used.
  • Such adjuvant oils as described in the preceding paragraphs may be employed as the carrier liquid in which an active compound is dissolved, emulsified or dispersed as appropriate to the physical form of the active compound.
  • The pesticidal formulations generally contain from 0.1 to 99% by weight, especially from 0.1 to 95% by weight, of a compound of formula I and from 1 to 99.9% by weight of a formulation adjuvant, which preferably includes from 0 to 25% by weight of a surface-active substance. Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations.
  • The rate of application of the compounds of formula I may vary within wide limits and depends upon the nature of the soil, the method of application (pre- or post-emergence; seed dressing; application to the seed furrow; no tillage application etc.), the crop plant, the weed or grass to be controlled, the prevailing climatic conditions, and other factors governed by the method of application, the time of application and the target crop. The compounds of formula I according to the invention are generally applied at a rate of 1-2000 g/ha, preferably 1-1000 g/ha and most preferably at 1-500 g/ha.

  • The finely ground active ingredient is intimately mixed with the adjuvants, yielding a suspension concentrate from which suspensions of any desired concentration can be prepared by dilution with water.
  • Crops of useful plants in which the compositions according to the invention can be used include especially cereals, in particular wheat and barley, rice, corn, rape, sugarbeet, sugarcane, soybean, cotton, sunflower, peanut and plantation crops.
  • The term “crops” is to be understood as also including crops that have been rendered tolerant to herbicides or classes of herbicides (for example ALS, GS, EPSPS, PPO and HPPD inhibitors) as a result of conventional methods of breeding or genetic engineering. An example of a crop that has been rendered tolerant e.g. to imidazolinones, such as imazamox, by conventional methods of breeding is Clearfield® summer rape (Canola). Examples of crops that have been rendered tolerant to herbicides by genetic engineering methods include e.g. glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady® and LibertyLink®. The weeds to be controlled may be both monocotyledonous and dicotyledonous weeds, such as, for example, Stellaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Sinapis, Lolium, Solanum, Echinochloa, Scirpus, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum, Rottboellia, Cyperus, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, Ipomoea, Chrysanthemum, Galium, Viola and Veronica. Control of monocotyledonous weeds, in particular Agrostis, Avena, Setaria, Lolium, Echinochloa, Bromus, Alopecurus and Sorghum is very extensive.
  • Crops are also to be understood as being those which have been rendered resistant to harmful insects by genetic engineering methods, for example Bt maize (resistant to European corn borer), Bt cotton (resistant to cotton boll weevil) and also Bt potatoes (resistant to Colorado beetle). Examples of Bt maize are the Bt-176 maize hybrids of NK® (Syngenta Seeds). The Bt toxin is a protein that is formed naturally by Bacillus thuringiensis soil bacteria. Examples of toxins and transgenic plants able to synthesise such toxins are described in EP-A-451 878, EP-A-374 753, WO 93/07278, WO 95/34656, WO 03/052073 and EP-A-427 529. Examples of transgenic plants that contain one or more genes which code for an insecticidal resistance and express one or more toxins are KnockOut® (maize), Yield Gard® (maize), NuCOTIN33B® (cotton), Bollgard® (cotton), NewLeaf® (potatoes), NatureGard® and Protexcta®. Plant crops and their seed material can be resistant to herbicides and at the same time also to insect feeding (“stacked” transgenic events). Seed can, for example, have the ability to express an insecticidally active Cry3 protein and at the same time be glyphosate-tolerant. The term “crops” is to be understood as also including crops obtained as a result of conventional methods of breeding or genetic engineering which contain so-called output traits (e.g. improved flavour, storage stability, nutritional content).
  • Areas under cultivation are to be understood as including land where the crop plants are already growing as well as land intended for the cultivation of those crop plants.

  • The compounds of formula I according to the invention can also be used in combination with safeners. Preferably, in these mixtures, the compound of the formula I is one of those compounds listed in Tables 1 to 57 below. The following mixtures with safeners, especially, come into consideration:
  • compound of formula I+cloquintocet-mexyl, compound of formula I+cloquintocet acid and salts thereof, compound of formula I+fenchlorazole-ethyl, compound of formula I+fenchlorazole acid and salts thereof, compound of formula I+mefenpyr-diethyl, compound of formula I+mefenpyr diacid, compound of formula I+isoxadifen-ethyl, compound of formula I+isoxadifen acid, compound of formula I+furilazole, compound of formula I+furilazole R isomer, compound of formula (I)+N-(2-methoxybenzoyl)-4-[(methylaminocarbonyl)amino]benzenesulfonamide, compound of formula I+benoxacor, compound of formula I+dichlormid, compound of formula I+AD-67, compound of formula I+oxabetrinil, compound of formula I+cyometrinil, compound of formula I+cyometrinil Z-isomer, compound of formula I+fenclorim, compound of formula I+cyprosulfamide, compound of formula I+naphthalic anhydride, compound of formula I+flurazole, compound of formula I+CL 304,415, compound of formula I+dicyclonon, compound of formula I+fluxofenim, compound of formula I+DKA-24, compound of formula I+R-29148 and compound of formula I+PPG-1292. A safening effect can also be observed for the mixtures compound of the formula I+dymron, compound of the formula I+MCPA, compound of the formula I+mecoprop and compound of the formula I+mecoprop-P.
  • The above-mentioned safeners and herbicides are described, for example, in the Pesticide Manual, Twelfth Edition, British Crop Protection Council, 2000. R-29148 is described, for example by P. B. Goldsbrough et al., Plant Physiology, (2002), Vol. 130 pp. 1497-1505 and references therein, PPG-1292 is known from WO09211761 and N-(2-methoxybenzoyl)-4-[(methylaminocarbonyl)amino]benzenesulfonamide is known from EP365484.
  • Benoxacor, cloquintocet-mexyl, cyprosulfamide, mefenpyr-diethyl and N-(2-methoxybenzoyl)-4-[(methylaminocarbonyl)amino]benzenesulfonamide are especially preferred, where cloquintocet-mexyl is particularly valuable.
  • The rate of application of safener relative to the herbicide is largely dependent upon the mode of application. In the case of field treatment, generally from 0.001 to 5.0 kg of safener/ha, preferably from 0.001 to 0.5 kg of safener/ha, and generally from 0.001 to 2 kg of herbicide/ha, but preferably from 0.005 to 1 kg/ha, are applied.
  • The herbicidal compositions according to the invention are suitable for all methods of application customary in agriculture, such as, for example, pre-emergence application, post-emergence application and seed dressing. Depending upon the intended use, the safeners can be used for pretreating the seed material of the crop plant (dressing the seed or seedlings) or introduced into the soil before or after sowing, followed by the application of the (unsafened) compound of the formula (I), optionally in combination with a co-herbicide. It can, however, also be applied alone or together with the herbicide before or after emergence of the plants. The treatment of the plants or the seed material with the safener can therefore take place in principle independently of the time of application of the herbicide. The treatment of the plant by simultaneous application of herbicide and safener (e.g. in the form of a tank mixture) is generally preferred. The rate of application of safener relative to herbicide is largely dependent upon the mode of application. In the case of field treatment, generally from 0.001 to 5.0 kg of safener/ha, preferably from 0.001 to 0.5 kg of safener/ha, are applied. In the case of seed dressing, generally from 0.001 to 10 g of safener/kg of seed, preferably from 0.05 to 2 g of safener/kg of seed, are applied. When the safener is applied in liquid form, with seed soaking, shortly before sowing, it is advantageous to use safener solutions which contain the active ingredient in a concentration of from 1 to 10 000 ppm, preferably from 100 to 1000 ppm.
  • It is preferred to apply the other herbicide together with one of the safeners mentioned above.
  • The following Examples illustrate the invention further but do not limit the invention.
    • PREPARATION EXAMPLES
  • Those skilled in the art will appreciate that certain compounds described below are β-ketoenols, and as such may exist as a single tautomer or as a mixture of keto-enol and diketone tautomers, as described, for example by J. March, Advanced Organic Chemistry, third edition, John Wiley and Sons. The compounds shown below, and in Table T1 are drawn as an arbitrary single enol tautomer, but it should be inferred that this description covers both the diketone form and any possible enols which could arise through tautomerism. Where more than one tautomer is observed in proton NMR, the data shown are for the mixture of tautomers. Furthermore, some of the compounds shown below are drawn as single enantiomers for the purposes of simplicity, but unless specified as single enantiomers, these structures should be construed as representing a mixture of enantiomers. Additionally, some of the compounds can exist as diastereoisomers, and it should be inferred that these can be present as a mixture of diastereoisomers or as any possible single diastereoisomer. Within the detailed experimental section the diketone tautomer is chosen for naming purposes, even if the predominant tautomer is the enol form.

    • Step 3: Preparation of 4-(5-bromo-2-trifluoromethoxyphenyl)-2,2,6,6-tetramethylpyran-3,5-dione
  • Figure US20140378305A1-20141225-C00053
  • To an ice-cold solution of concentrated sulphuric acid (10 ml) is added a second solution of 2-(5-bromo-2-trifluoromethoxyphenyl)-4,4,6,6-tetramethyl-1,5-dioxaspiro[2.4]heptan-7-one (6.34 g, 15.00 mmol) in 1,2-dichloroethane (10 ml) dropwise over 5 minutes. This biphasic mixture is stirred vigorously for 2 hours at 0° C., then poured into ice-water, rinsing with a small amount of additional 1,2-dichloroethane/water. This mixture is then concentrated under vacuum to remove all organic solvents, until a free-flowing solid was produced. The solid is filtered, washed with water then isohexane, followed by drying under vacuum overnight. The solid is next redissolved in ethyl acetate, dried over magnesium sulfate, filtered and the filtrate concentrated in vacuo to afford 4-(5-bromo-2-trifluoromethoxyphenyl)-2,2,6,6-tetramethylpyran-3,5-dione (4.17 g, 68%).
    • Step 4: Preparation of 4-[5-(4-chlorophenoxy)-2-trifluoromethoxyphenyl]-2,2,6,6-tetramethylpyran-3,5-dione
  • Figure US20140378305A1-20141225-C00054
  • To a mixture of 4-(5-bromo-2-trifluoromethoxyphenyl)-2,2,6,6-tetramethylpyran-3,5-dione (0.254 g, 0.62 mmol), 4-chlorophenol (0.400 g, 3.11 mmol), cesium carbonate (0.440 g, 1.25 mmol), copper (II) trifluoromethanesulfonate (11 mg, 0.03 mmol) and powdered 4 Å molecular sieves (0.40 g) is added anhydrous toluene (3.5 ml). After flushing with nitrogen the mixture is heated at 160° C. for 1 hour under microwave irradiation, then cooled to room temperature and quenched with 2M aqueous hydrochloric acid. The crude product is extracted with dichloromethane (×3), and the organic fractions are combined, washed with brine, dried over magnesium sulfate and concentrated in vacuo. Purification by preparative reverse phase HPLC affords 4-[5-(4-chlorophenoxy)-2-trifluoromethoxyphenyl]-2,2,6,6-tetramethylpyran-3,5-dione as a white powder.

  • Figure US20140378305A1-20141225-C00055
  • To a solution of 4-[4-ethyl-3-(2,2,6,6-tetramethyl-3,5-dioxotetrahydropyran-4-yl)phenoxy]-3-fluorobenzonitrile (0.130 g, 0.31 mmol) in dichloromethane at 0° C. is added triethylamine (0.133 ml, 0.95 mmol) followed by acetyl chloride (0.067 ml, 0.95 mmol). The mixture is stirred at 0° C. for 60 minutes, then allowed to warm to room temperature and stir for a further 18 hours. After concentration in vacuo the crude product is purified by flash column chromatography on silica gel (iso-hexane/ethyl acetate eluant) to afford 4-[5-(4-cyano-2-fluorophenoxy)-2-ethylphenyl]-2,2,6,6-tetramethyl-5-oxo-5,6-dihydro-2H-pyran-3-yl ester.

    • BIOLOGICAL EXAMPLES
  • Seeds of a variety of test species were sown in standard soil in pots. After cultivation for one day (pre-emergence) or after 8 days cultivation (post-emergence) under controlled conditions in a glasshouse (at 24/16° C., day/night; 14 hours light; 65% humidity), the plants were sprayed with an aqueous spray solution derived from the formulation of the technical active ingredient in acetone/water (50:50) solution containing 0.5% Tween 20 (polyoxyethelyene sorbitan monolaurate, CAS RN 9005-64-5). The test plants were then grown in a glasshouse under controlled conditions in a glasshouse (at 24/16° C., day/night; 14 hours light; 65% humidity) and watered twice daily. After 13 days for pre and post-emergence, the test was evaluated (100=total damage to plant; 0=no damage to plant).
