Description

REGULATION OF GROWTH OF PLANTS I DESCRIPTIVE MEMORY The present invention relates to the technical field of agrochemicals and to methods used in agriculture for the regulation of the growth of plants. In particular, the present invention relates to a new class of plant growth regulating agents for the treatment of plants for the purpose of inducing growth regulating responses, which result in superior growth of treated plants, of certain parts of the plants or, more generally, a superior yield of the crops. The term "method for regulating the growth of plants" or the term "growth regulation procedure" or the use of the words "regulation of plant growth" or other terms that use the word "regular", such as used in the present specification, they refer to a variety of plant responses that improve some characteristic of the plant. The "growth regulating agents of plants" are compounds that possess an activity in one or more process (s) for the regulation of the growth of a plant. This type of regulation of plant growth is distinguished from a pesticide action or a reduction in growth, which is sometimes also defined as regulation of the growth of plants, whose intention, however, is to destroy or prevent growth of a plant. For this reason, the compounds used in the practice of this invention are used in amounts that are not phytotoxic with respect to the plant being treated, but which stimulate the growth of the plant or certain parts thereof. Therefore, said compounds can also be referred to as "plant stimulants", and their action can be referred to as "stimulation of plant growth". Regulation of plant growth is a desirable way to improve plants and their harvest in such a way that improved plant growth and better conditions of agricultural practice are obtained compared to untreated plants. This class of molecules can either inhibit or favor cellular activities, often with a lower specificity, compared to that of animal hormones. This means that the plant growth regulating agents identified in plants most often regulate the division, elongation and differentiation of plant cells in such a way that, most often, they have multiple effects on plants. On the molecular basis, plant growth regulating agents may work by affecting membrane properties, controlling gene expression or affecting enzyme activity, or being active in a combination of at least two of the types of interactions that before they have been mentioned. The plant growth regulating agents are chemical products or of natural origin, also called plant hormones (such as non-peptide hormones, for example auxins, gibberellins, cytokinins, ethylene, brassinosteroids or abscisic acid, and salicylic acid), lipooligosaccharides ( for example Nod factors), peptides (for example systemin), fatty acid derivatives (for example jasmonatos), and oligosaccharins (for its compilation see the work: Biochemistry &Molecular Biology of the Plant (2000) [Biochemistry &Molecular Biology of the Plant] (2000), editing coordinators Buchanan, Gruissem, Jones, pages 558-562, and 850-929), or may be products produced by synthesis (such as derivatives of plant growth hormones that occur in the nature, ethephon). Plant growth regulating agents, which work in very small concentrations, can be found in a large number of cells and tissues, but appear to be concentrated in meristems and buds. Next to the selection of the correct compound, it is also important to look for optimal environmental conditions, since several factors that can affect the action of growth hormones are known, such as (a) the concentration of the plant growth regulating agent, properly speaking, (b) the amount applied to the plant, (c) the time of application in relation to the date of flowering, (d) the temperature and humidity before and after the treatment, (e) the moisture content of the plants, and various other . Plant growth regulators may be beneficial for plants, but can sometimes be used to control weeds or to induce defoliation (as do the synthetic auxins 2,4-D and 2,4). , 5-T). The mode of action of the existing regulators of plant growth is not often known. Various goals are discussed and, among these, most of the affected molecules are involved in the regulation of cell division, such as the cell cycle arrest in stage G1 or G2, respectively, others are to signal responses to drought stresses (Biochemistry &; Molecular Biology of the Plant (2000); editing coordinators Buchanan, Gruissem, Jones, pages 558-560). In any case, hormonal control can be identified as an extremely complex cascade of regulations in ascending and descending directions that, for example, can lead to a stimulation of the growth of an organ or a cell type of a plant, but can also lead to a repression in other organs or cell types of the same plant. In many cases, certain kinases are involved either directly or indirectly in the control of plant hormones, and among kinases, protein kinases are primordial and very specific control molecules with respect to cell cycle control. Said kinases are discussed as targets for various plant hormones, as is the case for an auxin and abscisic acid (Biochemistry &Molecular Biology of the Plant (2000); editing coordinators Buchanan, Gruissem, Jones, pages 542-565 and pages 980-985; Morgan (1997), Annu., Rev. Cell. Dev.
Biol., 13, 261-291; Amon et al. (1993), Cell, 74, pages 993-1,007; Dynlacht et al. (1997), Nature, 389, pages 149-152; Hunt and Nasmyth (1997), Curr. Opin. Cell. Biol., 9, pages 765-767; Thomas and Hall (1997), Curr. Opin. Cell. Biol., 9, pages 782-787). The international patent application publication WO 96/33614 already describes the use of an N-arylpyrazole or N-heteroarylpyrazole compound to regulate the growth of plants. In addition, U.S. Pat. with the publication number US 4,810,283 describes the use of N-arylpyrazoles as herbicides. The numbers of patent publications, international WO 87/03781, European EP 0295117, from the USA US 5556873, US 4771066 and international WO 02/066423 describe the repression of insects, arachnids and helminths with 1-arylpyrazoles compounds. In view of the foregoing, it has now been found, surprisingly, that certain derivatives of substituted 1-arylpyrazole-3-carboxylic acids in position 5, and especially certain derivatives of 5-amino-1-arylpyrazole-3-carboxylic acids do not They act mainly as herbicides, but show a superior behavior with respect to their use for the regulation of the growth of plants.

In this context, it is possible to automate the process of the reaction, the treatment or the purification of the products or of the intermediates. In total, it is to be understood that this means a process as described, for example, by S.H. DeWitt in "Annual Reports in Combinatorial Chemistry and Molecular Diversity: Automated Synthesis" [Annual Reports on Combinatorial Chemistry and Molecular Diversity: Automatic Synthesis], Volume 1, published by Escom., 1997, pages 69 to 77. To carry out the reaction and the treatment in a parallel manner, a series of commercially available equipment may be used, such as are available, for example, from Stem Corporation, Woodrolfe Road, Tollesbury, Essex, CM9 8SE England, or from Radleys Discovery Technologies, Saffron Walden, Essex, CB11 3AZ, England. To carry out the parallel purification of compounds (I), or intermediate compounds obtained during the preparation, there are available, among others, chromatography equipment, for example those from ISCO, Inc., 4700 Superior Street, Lincoln, NE 68504 , USA The mentioned equipment makes possible a modular procedure, in which the individual steps of the process are automatic, but between the steps manual operations must nevertheless be carried out. This can be avoided by using partially or fully integrated automation systems, in which the automation modules in question are manipulated, for example, by means of robots or robots. Such automation systems can be purchased for example from Zymark Corporation, Zymark Center, Hopkinton, MA 01748, USA. In addition to the methods described above, the compounds of the formula (I) can be prepared by methods that are fully or partially supported in solid phases. For this purpose, individual intermediates, or all intermediates of the synthesis or of a synthesis adapted to accommodate the process in question, are made in a manner fixed to a synthetic resin. Methods of synthesis that are supported by solid phases have been described extensively in the specialized literature, for example in the citation of: Barry A. Bunin in "The Combinatorial Index", published by Academy Press, 1998. The use of synthesis methods, which are supported by solid phases, allows a series of protocols that are known from the bibliography that, in turn, can be performed in a manual or automatic way. For example, the "tea bag method" (by Houghten, see U.S. Patent 4,631,211).; and the appointment of Houghten et al., Proc. Nati Acad. Sci., 1985, 82, 5,131-5,135) can be partially automated with IRORI products, 11149 North Torrey Pines Road, La Jolla, CA 92037, USA. Parallel syntheses, which are supported by solid phases, can be successfully automated, for example using equipment from Argonaut Technologies, Inc., 887 Industrial Road, San Carlos, CA 94070, USA or from MultiSynTech GmbH, Wullener Feld 4, 58454 Witten, Germany.

Another aspect of the invention is a method for regulating growth in plant tissues of monocotyledonous or dicotyledonous plants, said method comprising applying to plant tissue cultures an appropriate amount of a compound having the formula (I), either alone or together with at least one additional active compound selected from among the set of plant growth regulating agents or plant hormones. The compounds of the formula (I) can preferably be used as plant growth regulating agents in monocotyledonous or dicotyledonous cultivated plants., preferably selected from among the set of economically important field-grown plants, such as, for example, wheat, barley, rye, triticale, rice, corn, sugar beet, cotton, or soybean, particularly corn, wheat and soybeans, as well as vegetables and ornamental plants, which have been made of this nature through genetic engineering. Traditional ways of generating new plants that have modified characteristics compared to existing plants, consist, for example, in traditional methods of cultivation and in the generation of mutants. However, it is also possible to generate new plants with altered characteristics with the aid of genetic engineering methods (see, for example, EP-A-0221044 and EP-A-0131624). For example, several cases of genetic engineering modifications of cultivated plants have been described for the purpose of modifying the starch synthesized in the plants (see, for example, WO 92/11376, WO 92/14827, WO 91/19806), - transgenic cultivated plants that are resistant to certain glufosinate type herbicides (compare, for example, EP-A-0242236, EP-A-242246) or glyphosate type (WO 92/00377) or type of sulfonylureas (EP-A-0257993 and US-A-5013659), - transgenic cultivated plants, for example cotton, which are capable of producing Bacillus thuringiensis toxins (Bt toxins) which make the plants resistant to specific pests ( EP-A-0142924, EP-A-0193259), - transgenic cultured plants whose fatty acid spectrum has been modified (WO 91/13972). A large number of techniques in molecular biology, by means of which new transgenic plants with altered characteristics can be generated, are known in principle; see, for example, the citations of Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2nd edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y .; or from Winnacker "Gene und Klone" [Genes and clones], VCH Weinheim, 2nd edition 1996, or from Christou, "Trends in Plant Science" [Trends in plant science] 1 (1996), 423-431). In order to perform such manipulations by genetic engineering, nucleic acid molecules can be introduced into plasmids, which allow mutagenesis or a change of sequences by means of a recombination of DNA sequences. It is possible, for example, with the help of the aforementioned classical methods, to perform base exchanges, eliminate subsequences or add natural or synthetic sequences. To connect the DNA fragments with one another, adapters or crimpers can be attached to the fragments. For example, plant cells can be generated with reduced activity of a gene product, by expressing at least one corresponding antisense RNA, an RNA of the same sense to achieve a concomitant suppressive effect, or by expressing at least one ribozyme of appropriate construction, which specifically dissociates transcripts of the aforementioned gene product. For this purpose, it is possible to make use, on the one hand, of DNA molecules that span the entire coding sequence of a gene product, including any flanking sequences that may be present, and, on the other hand, of DNA molecules that only they encompass parts of the coding sequence, but these parts must be sufficiently long in order to produce an antisense effect in the cells. One can also make use of DNA sequences which show a high degree of homology with the coding sequences of a gene product, but which are not completely identical. When nucleic acid molecules are expressed in plants, the protein that has been synthesized can be located in any desired compartment of the plant cell. However, in order to achieve a location in a particular compartment, it is possible, for example, to link the coding region with DNA sequences that guarantee localization in a particular compartment. Such sequences are known to a skilled professional (see, for example, the citations of Braun et al., EMBO J. 11 (1992), 3,219-3,227, Wolter et al., Proc. Nat. Acad. Sci. USA 85 (1988). , 846-850; Sonnewald et al., Plant J. 1 (1991), 95-106).
The cells of transgenic plants can be regenerated by known techniques to give whole plants. In principle, the transgenic plants can be plants of any desired plant species, ie monocotyledonous and also dicotyledonous plants. This allows transgenic plants that exhibit altered characteristics to be obtained by overexpression, suppression or inhibition of genes or sequences of homologous genes (= natural), or by expression of genes or sequences of heterologous (= foreign) genes. The compounds of the formula (I) can preferably be used in transgenic plant cultures which are resistant to herbicides taken from the group of sulfonylureas, glufosinateammonium or glyphosatoisopropylammonium and analogous active substances which show altered phenotypes, such as, but not limited to , characteristics such as a modification of the content, an altered flowering time, male or female sterile plants, plants resistant to the environment due to an expression or repression of endogenous or exogenous genes in the cultivated transgenic plant. The use according to the invention for the regulation of the growth of plants also includes the case in which the compounds of the formula (I) are formed only in the plant or in the soil from a precursor ("prodrug"). ") after its application to the plant.
The compounds of the formula (I) can be used in conventional formulations such as wettable powders, emulsifiable concentrates, sprayable solutions, dusts or granules. The invention therefore also relates to plant growth regulating compositions comprising compounds of the formula (I). According to a further feature of the present invention, there is provided a plant growth regulating composition, comprising an effective amount of a compound of the formula (I), as defined above, or an acceptable salt in agriculture thereof, in association with, and preferably homogeneously dispersed in, one or more diluents or carriers acceptable in agriculture and compatible, and / or agents with surface activity [i.e., diluents or carriers and / or agents with surface activity of the type generally accepted in the art as suitable for use in herbicidal compositions, and which are compatible with the compounds of the invention]. The term "homogeneously dispersed" is used to include compositions in which the compounds of the formula (I) are dissolved in other components. The term "growth regulating composition" is used in a broad sense, to include not only compositions that are ready for use as herbicides, but also concentrates that must be diluted before use (including tank mixes).
The compounds of the formula (I) can be formulated in various ways, depending on the prevailing biological and / or chemical-physical parameters. Examples of possible formulations that are appropriate are: wettable powders (WP), water soluble powders (SP), water soluble concentrates, emulsifiable concentrates (EC), emulsions (EW), such as emulsions of the oil in water type and water in oil, sprayable solutions, concentrates to suspend (SC), dispersions on an oil or water base, solutions that are miscible with an oil, suspensions to encapsulate (CS), dusting powder (DP), seed disinfectant products granules for spreading and for application on the ground, granules (GR) in the form of microgranules, granules formed by projection, coated granules and granules formed by adsorption, granules dispersible in water (WG), granules soluble in water (SG) , ULV formulations (ultra high volume), microcapsules and waxes. These types of individual formulations are known in principle and are described, for example, in the works of: Winnacker-Küchler, "Chemische Technologie" [Chemical Technology], volume 7, C. Hauser publishing house, Munich, 4th edition of 1986; Wade van Valkenburg, "Pesticide Formulations", Marcel Dekker, N.Y., 1973; K. Martens, "Spray Drying Handbook", 3rd edition, G. Goodwin Ltd, London, 1979; The necessary formulation aids, such as inert materials, surfactants, solvents and other additives, are also known, and are described, for example, in the works of: Watkins, "Handbook of Insecticide Dust Diluents and Carriers". diluents and fine powder insecticide supports], 2nd edition, Darland Books, Caldwell NJ; H.v. Olphen, "Introduction to Clay Colloid Chemistry", 2nd edition, J. Wiley & Sons, N.Y .; C. Marsden, "Solvents Guide" [Solvent Guide], 2nd edition, Interscience, N.Y. 1963; "Detergents and Emulsifiers Annual" by McCutcheon, MC Publ. Corp., Ridgewood N.J .; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., N.Y. 1964; Schonfeldt, "Grenzfláchenaktive Áthylenoxidaddukte" [Adducts with interfacially active ethylene oxide], Wiss. Verlagsgesellschaft, Stuttgart 1976; Winnacker-Küchler, "Chemische Technologie" [Chemical Technology], volume 7, editorial C. Hauser Munich, 4th edition, 1986. Based on these formulations, it is also possible to prepare combinations with active substances such as pesticides, such as, for example, insecticides , acaricides, herbicides, fungicides, and with antidotes, fertilizers and / or growth regulators, for example in the form of a prepared mixture or a mixture in storage. Wettable powders are formulations which are uniformly dispersible in water and which, in addition to the compounds of the formula (I), also comprise ionic and / or nonionic surfactants (wetting agents, dispersants), for example poly (oxyethylated) alkylphenols, alcohols poly (oxyethylated) fatty amines, poly (oxyethylated) fatty amines, (fatty alcohol) -polyglycol ether sulfates, alkane sulphonates or alkylbenzenesulfonates, sodium lignosulfonate, sodium 2,2'-dinaphthylmethane-6,6'-disulfonate, dibutylnaphthalene sulfonate sodium or sodium oleoylmethyltaurate, in addition to a diluent or inert substance. To prepare the wettable powders, the compounds of the formula (I) are, for example, finely ground in conventional apparatuses such as hammer mills, blower mills and air jet mills, and mixed with the formulation aids, and either concomitantly or following this. The emulsifiable concentrates are prepared, for example, by dissolving the compounds of the formula (I) in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or aromatics or high-boiling hydrocarbons or mixtures thereof, with addition of one or more ionic and / or nonionic surfactants (emulsifiers). Emulsifiers which may be used are, for example: calcium salts of alkylarylsulfonic acids, such as calcium dodecylbenzenesulfonate, or nonionic emulsifiers, such as polyglycol esters of fatty acids, alkylaryl polyglycol ethers, (fatty alcohol) polyglycol ethers, condensates of propylene oxide and ethylene oxide, alkylpolyethers, sorbitan esters, such as esters with sorbitan fatty acids or poly (oxyethylene) sorbitan esters, such as poly (oxyethylene) esters with sorbitan fatty acids.
The dusts are obtained by grinding the active substance with finely divided solid substances, for example talc or natural clays, such as kaolin, bentonite or pyrophyllite, or diatomaceous earth. The concentrates for suspending may be based on water or an oil. They can be prepared, for example, by wet grinding by means of commercially available bead mills, if appropriate with the addition of surfactants, as already mentioned above for example in the case of the other types of formulations. Emulsions, for example oil-in-water (EW) type emulsions, can be prepared for example by means of stirrers, colloid mills and / or static mixers using aqueous organic solvents and, if appropriate, surfactants, such as those they have already been mentioned above, for example, in the case of the other types of formulations. The granulates can be prepared either by casting the compounds of the formula (I) on an inert granulated adsorbent material, or by applying concentrates of active substances on the surface of supports such as sand, kaolinites or an inert granulated material, by means of binding agents. , for example, a polyvinyl alcohol, a poly (sodium acrylate), or alternatively mineral oils. Suitable active substances can also be granulated in the manner that is conventional for the production of granules of fertilizers, if desired in a mixture with fertilizers. The water-dispersible granules are prepared, as a rule, by standard methods, such as spray drying, fluidized-bed granulation, disk granulation, mixing in high-speed mixers and extrusion without any solid inert material. For preparing disc-shaped, fluidized bed, extruder and projection granules, see, for example, the procedures outlined in the works: "Spray Drying Handbook", 3rd edition of 1979, G. Goodwin Ltd, London; J.E. Browning, "Agglomeration" (Agglomeration), Chemical and Engineering 1967, pages 147 et seq .; "Perry's Chemical Engineer = s Handbook," 5th edition, McGraw-Hill, New York 1973, pages 8-57. For more details about the formulation of agents for the protection of cultivated plants, see, for example, the works of G.C. Klingman, "Weed Control as a Science", John Wiley and Sons, Inc., New York, 1961, pages 81-96 and J.D. Freyer, S.A. Evans, "Weed Control Handbook", 5th edition, Blackwell Scientific Publications, Oxford, 1968, pages 101-103. As a general rule, agrochemical formulations comprise from 0.1 to 99% by weight, in particular from 0.1 to 95% by weight, of compounds of the formula (I).
The concentration of compounds of the formula (I) in wettable powders is, for example, from about 10 to 90% by weight, the remainder being made up to 100% by weight by common formulation components. In the case of emulsifiable concentrates, the concentration of compounds of the formula (I) can be up to about 1 to 90, preferably 5 to 80% by weight. The formulations in the form of the dusts are usually from 1 to 30% by weight of compounds of the formula (I), preferably in most cases from 5 to 20% by weight of the compounds of the formula (I) ), while the projected solutions comprise approximately 0.05 to 80, preferably 2 to 50% by weight, of compounds of the formula (I). In the case of water-dispersible granules, the content of compounds of the formula (I) depends in part on whether the compounds of the formula (I) are in a liquid or solid form, and of which the granulation aids are, loading and filling materials and the like that are being used. The dispersible granules in water, for example, they comprise between 1 and 95% by weight of an active substance, preferably between 10 and 80% by weight. In addition, the formulations of compounds of the formula (I) mentioned, if appropriate, comprise adhesives, wetting agents, dispersants, emulsifiers, penetrants, preservatives, antifreeze and antifreeze agents, solvents, fillers and fillers, supports, dyes, defoamers, evaporation inhibitors, pH regulators and viscosity regulators, which are conventional in each case. Appropriate formulations are known for plant growth regulating compositions. A description of suitable formulations that can be used in the method of the invention can be found in the international patent publications WO 87/3781, WO 93/6089 and WO 94/21606 as well as in the European patent application EP 295117 and in U.S. Patent 5,232,940, Formulations or compositions intended for uses in the regulation of plant growth can be produced in a similar manner, by adapting the ingredients, if necessary, to make them more appropriate for the plant or the plant. floor in which the application has to be made. The compounds of the formula (I) or their salts can be used as such or in the form of their preparations (formulations) as combinations with other active substances such as pesticides such as, for example, insecticides, acaricides, nematicides, herbicides, fungicides, antidotes, fertilizers and / or other growth regulating agents, for example as a premix or as a tank mix. It has been found that, surprisingly, the compounds of the formula (I) and in a very special way the compounds 1.1; 1.2 1.3; 1.4; 1.5; 1.6; 1.7; 1.8; 1.9; 1.10; 1.11; 1.12; 1.13; 1.34; 1.35; 1.36; 1.37 1.65; 1.96; 1.123; 1,133; 1,134; 1,135; 1,136; 1,137; 1,138; 1,139; 1,140 1,141; 1,142; 1,143; 1,144; 1,145; 1,166; 1,167; 1,168; 1,169; 1,197; 1,228 1,255; 1,268; 1,329; 1.399; 1,400; 1,461; 1.532; 1,664; 1,796; 2.1; 2.10; 2.11; 3.2; 3.3; 3.4; and 3.10 play an important role in regard to the growth properties of the plants, which may be different due to an application to various cultivated plants. For example, compound 1136 shows significant effects of approximately the same magnitude when used as a regulatory agent of plant growth in corn and wheat, but in different concentrations. Compound 1141 shows a remarkable effect as a plant growth regulating agent in corn and a superior effect in wheat. By virtue of the practice of the present invention a wide variety of plant growth responses can be induced, including the following ones (enumeration without order of importance): a) a more developed system of roots b) increase of shoot formation c) increase in the height of the plants d) larger sheet of the leaves e) less dead basal leaves f) stronger shoots g) green color of the leaves h) less fertilizers are needed i) fewer seeds are needed j) more productive shoots k) less third non-productive shoots I) earlier flowering m) early maturity of the grains n) less overturning of the plants (bedding) o) longer panicles p) increased growth of the shoots q) improved vigor of the plants r) early germination s) more fruits and better yield. It is intended that, as used herein, the term "method for the regulation of plant growth" or "plant growth regulation" means the achievement of any of the nineteen categories of responses that were previously have mentioned or any other modification of a plant, a seed, a fruit or a legume (regardless of whether the fruit or the vegetable is harvested or not harvested) as long as the net result is to increase growth or profit for any plant, seed, fruit or vegetable property as distinct from any pesticide action (unless the present invention is practiced in conjunction with, or in the presence of, a pesticide, eg, a herbicide). The term "fruit" as used in the present specification, is to be understood as meaning anything of economic value that is produced by the plant.
Preferably, at least an increase of 10% of one or more of the respective growth responses of the plants is obtained.
The 5-amino-1-arylpyrazole-3-carboxylic acid derivative of the formula (I) can be applied for purposes of regulating the growth of plants to the foliage of plants and / or to the soil in which said plants are growing. Applications to the soil are often carried out in the form of granules, which are usually applied in an amount sufficient to provide a rate from about 0.00001 kg / ha to about 0.5 kg / ha of the active ingredient, preferably between 0.00001 and 0.1 kg / ha, more preferably between 0.00001 kg / ha and 0.01 kg / ha. A preferred embodiment of the invention consists in a method for the regulation of the growth of the plants, which comprises applying to the seeds from which said plants grow, before said sowings, a non-phytotoxic amount effective to regulate the growth of the plants. plants, of a compound having the formula (I). The seeds can be treated, especially by coating or embedding or impregnation or soaking or immersion in liquid or pasty formulations, which are known per se, and subsequently can be dried. The seeds comprising from 0.1 to 1000 grams (g) per 100 kilograms (kg) of a compound of the formula (I), preferably from 0.1 to 800 g per 100 kg, most preferably from 0.1 to 250 g per 100 kg, they are particularly appropriate for this purpose. The exact amount of the 5-amino-1-arylpyrazole-3-carboxylic acid derivative of the formula (I), which is to be used, will depend, among other things, on the particular species of plant being treated. An appropriate dose can be determined by a person skilled in the art by routine experimentation. The response of the plant will depend on the total amount of compound used, as well as the particular species of plant being treated. Of course, the amount of the 5-amino-1-arylpyrazole-3-carboxylic acid derivative of the formula (I) should not be phytotoxic with respect to the plant being treated. Although the preferred method of application of the compounds used in the process of this invention is directed directly to the foliage and stems of the plants, the compounds can be applied to the soil in which the plants are growing. The following examples are illustrative of methods for regulating the growth of plants according to the invention, but should not be understood as limiting the invention, since certain modifications in materials and methods will be apparent to a skilled artisan. All measurements of plant growth regulating effects were determined either using a protoplast scrutiny assay and / or using a root growth assay and / or by applying the previously selected compounds to the above defined test system under natural conditions of growth in tests in the field. In all cases, protoplasts, plants or parts of plants or untreated seeds were taken as controls.
B. BIOLOGICAL EXAMPLES EXAMPLE 1 Plant protoplast system The present invention features a so-called high-flow rate assay for rapid screening of chemical compounds that modulate cell growth. The test generally involves: a) protoplasts from plants that have grown in a liquid medium, b) a library of chemical compounds, and c) screening the protoplasts to identify compounds that significantly affect the growth and development of the cells.
Preparation of the protoplasts Preferably, the protoplasts were prepared from suspensions of cells derived from corn stems. The protoplasts were obtained by enzymatic digestion of the aggregates of cells in the suspension. The cells were digested for 3-6 hours at room temperature in a mixture of cellulase and pectolyase, the protoplasts were released by gentle shaking, filtered through a 45 μm mesh and collected by centrifugation. After digestion, the protoplasts were washed several times to remove cell debris and enzyme debris, and then resuspended in a culture medium. The protoplasts were plated in 50-100 μl aliquots into microtiter wells with a density ranging from 100,000 to 2,000,000 protoplasts per ml, preferably at a concentration of 800,000 protoplasts / ml.
Screening assay To identify chemical compounds that modulate cell growth, corn protoplasts were incubated with a library of chemical compounds in 96-well microtiter plates. After incubation at 25 ° C for 1-14 days, preferably 7-10 days, the protein content was measured by colorimetric assays based on Coomassie dye. The growth of the cells treated with the chemical compounds involved in the assay was detected by comparison with untreated protoplasts. The treatment with a section of compounds derived from the formula (I) shows an increase of more than 50% with respect to an untreated control.
EXAMPLE 2 Root growth test The roots of the plants are a proliferative tissue in high degree, which allows an easily accessible, cheap and short term method of scrutiny, for agents that regulate the growth of plants. The results obtained can easily be transferred to the overall effects on a plant of the growth regulating agents of the plants identified by said system. Using this root test, it is possible for a person to determine the effect of a seed treatment for root growth and / or germination and / or changes in the habitat of germinated plants in order to identify possible use as a performance enhancing agent. Two seeds of wheat (Triticum aestivum, variety "TRISO") or 1 seed of corn (Zea mays, variety "LORENZO") per hole in a tray of plastic material containing an architecture of 8 x 13 holes, were placed on a soil with compost, covered with sand. These seeds were treated 100 μl / hole, which creates an application volume of approximately 1200 l / ha, of a solution of a compound at active ingredient regimes equivalent to 100, 10 and 1 g ai / ha of each compound using a robotic application system (Lizzy Spray Robotics). Six replications were made in a row of each compound and each concentration. The outer edge of the plastic material tray, which was previously defined, was left untreated to avoid false negative effects and the central row (No. 7) was used as an untreated control. The treated seeds were allowed to dry for approximately 4 hours and subsequently were covered with sand and watered. The trays were stored in chambers with 14 hours of illumination at a temperature of 24 ° C (± 2) during the day and 16 ° C (± 2) at night and with a relative humidity (hr) of 60%, and They were watered daily. The determinations were made at 16 (± 2) days after the treatment, recounting the germinated plants and checking the symptoms and the phytotoxicity percentage. In addition, the roots were washed and the rods were cut directly above the seeds and the wet roots were placed on dry paper towels for approximately 30 minutes and weighed later. This procedure provides a similar degree of moisture to the roots, so that a comparison of the weights is possible. Table 4 shows the results of some of the compounds (Cpd) claimed as being effective in regulating the growth of plants in regard to corn. The effects observed in regard to the Root Growth outlined in column 2 (a Root Growth of "100" is established as the pattern) are directed to concentrations that are equivalent to 100, 10, 1 g of ia / ha, of each one.
TABLE 4 Table 5 shows the results of some of the compounds (Cpd) claimed as being effective in regulating the growth of plants as regards wheat. The effects observed in regard to Root Growth reported in column 2 (a root growth of "100" is established as the standard) are directed to concentrations that are equivalent to 100, 10, 1 g ai / ha, of each one.
TABLE 5 EXAMPLE 3 Test in the field Magister and Zamora hybrid corn seeds were seeded and treated with compound 1136 at the rate of 1 g / 100 kg of seeds (0.0003 kg / ha).
The field tests were established in a dissociated plot design, which represents the plants treated with compounds of the formula (I) as well as the untreated control plants. The results showed an increase in grain yield of up to 119% in the case of the Magister hybrid and up to 131% in the case of the Zamora hybrid, compared to the yield obtained with untreated control plants in each case.
