Agrochemical Composition

[0528] Another aspect of the present invention relates to an agrochemical composition including an agrochemically acceptable carrier or diluent and a compound according to the aspects of the present invention. The agrochemical composition can contain one or more of the above-identified compounds of the present invention. Typically, the agrochemical composition of the present invention will include a compound of the present invention or its agrochemically acceptable salt, as well as an agrochemically acceptable carrier or diluent. The term “agrochemically acceptable carrier” refers to any suitable adjuvants, carriers, excipients, or stabilizers, and can be in solid or liquid form such as sprays, aerosols, powders, solutions, suspensions, or emulsions.

[0529] The compounds according to the invention can be used as herbicidal agents in unmodified form, but they are generally formulated into compositions in various ways using formulation adjuvants, such as carriers, solvents and surface-active substances. The formulations can be in various physical forms, e.g. in the form of dusting powders, gels, wettable powders, water-dispersible granules, water-dispersible tablets, effervescent pellets, emulsifiable concentrates, microemulsifiable concentrates, oil-in-water emulsions, oil-flowables, aqueous dispersions, oily dispersions, suspo-emulsions, capsule suspensions, emulsifiable granules, soluble liquids, water-soluble concentrates (with water or a water-miscible organic solvent as carrier), impregnated polymer films or in other forms known. Such formulations can either be used directly or diluted prior to use. The dilutions can be made, for example, with water, liquid fertilizers, micronutrients, biological organisms, oil or solvents.

[0530] Typically, the composition will contain from about 0.01 to 99 percent, preferably from about 20 to 75 percent of active compound(s), together with the adjuvants, carriers and/or excipients. While individual needs may vary, determination of optimal ranges of effective amounts of each component is within the skill of the art.

[0531] The formulations can be prepared e.g. by mixing the active ingredient with the formulation adjuvants in order to obtain compositions in the form of finely divided solids, granules, solutions, dispersions or emulsions. The active ingredients can also be formulated with other adjuvants, such as finely divided solids, mineral oils, oils of vegetable or animal origin, modified oils of vegetable or animal origin, organic solvents, water, surface-active substances or combinations thereof.

[0532] The active ingredients can also be contained in very fine microcapsules. Microcapsules contain the active ingredients in a porous carrier. This enables the active ingredients to be released into the environment in controlled amounts (e.g. slow-release). Microcapsules usually have a diameter of from 0.1 to 500 microns. They contain active ingredients in an amount of about from 25 to 95% by weight of the capsule weight. The active ingredients can be in the form of a monolithic solid, in the form of fine particles in solid or liquid dispersion or in the form of a suitable solution. The encapsulating membranes can comprise, for example, natural or synthetic rubbers, cellulose, styrene/butadiene copolymers, polyacrylonitrile, polyacrylate, polyesters, polyamides, polyureas, polyurethane or chemically modified polymers and starch xanthates or other polymers that are known to the person skilled in the art. Alternatively, very fine microcapsules can be formed in which the active ingredient is contained in the form of finely divided particles in a solid matrix of base substance, but the microcapsules are not themselves encapsulated.

[0533] The formulation adjuvants that are suitable for the preparation of the compositions according to the invention are known per se. As liquid carriers there may be used: water, toluene, xylene, petroleum ether, vegetable oils, acetone, methyl ethyl ketone, cyclohexanone, acid anhydrides, acetonitrile, acetophenone, amyl acetate, 2-butanone, butylene carbonate, chlorobenzene, cyclohexane, cyclohexanol, alkyl esters of acetic acid, diacetone alcohol, 1,2-dichloropropane, diethanolamine, p-diethylbenzene, diethylene glycol, diethylene glycol abietate, diethylene glycol butyl ether, diethylene glycol ethyl ether, diethylene glycol methyl ether, dimethylformamide (DMF), dimethyl sulfoxide (DMSO), 1,4-dioxane, dipropylene glycol, dipropylene glycol methyl ether, dipropylene glycol dibenzoate, diproxitol, alkylpyrrolidone, ethyl acetate, 2-ethylhexanol, ethylene carbonate, 1,1,1-trichloroethane, 2-heptanone, alpha-pinene, d-limonene, ethyl lactate, ethylene glycol, ethylene glycol butyl ether, ethylene glycol methyl ether, gamma-butyrolactone, glycerol, glycerol acetate, glycerol diacetate, glycerol triacetate, hexadecane, hexylene glycol, isoamyl acetate, isobornyl acetate, isooctane, isophorone, isopropylbenzene, isopropyl myristate, lactic acid, laurylamine, mesityl oxide, methoxypropanol, methyl isoamyl ketone, methyl isobutyl ketone, methyl laurate, methyl octanoate, methyl oleate, methylene chloride, m-xylene, n-hexane, n-octylamine, octadecanoic acid, octylamine acetate, oleic acid, oleylamine, o-xylene, phenol, polyethylene glycol, propionic acid, propyl lactate, propylene carbonate, propylene glycol, propylene glycol methyl ether, p-xylene, toluene, triethyl phosphate, triethylene glycol, xylenesulfonic acid, paraffin, mineral oil, trichloroethylene, perchloroethylene, ethyl acetate, amyl acetate, butyl acetate, propylene glycol methyl ether, diethylene glycol methyl ether, methanol, ethanol, isopropanol, and alcohols of higher molecular weight, such as amyl alcohol, tetrahydrofurfuryl alcohol, hexanol, octanol, ethylene glycol, propylene glycol, glycerol, methyl-2-pyrrolidone and the like.

[0534] Suitable solid carriers are, for example, talc, titanium dioxide, pyrophyllite clay, silica, attapulgite clay, kieselguhr, limestone, calcium carbonate, bentonite, calcium montmorillonite, cottonseed husks, wheat flour, soybean flour, pumice, wood flour, ground walnut shells, lignin and similar substances.

[0535] A large number of surface-active substances can advantageously be used in both solid and liquid formulations, especially in those formulations which can be diluted with a carrier prior to use. Surface-active substances may be anionic, cationic, non-ionic or polymeric and they can be used as emulsifiers, wetting agents or suspending agents or for other purposes. Typical surface-active substances include, for example, salts of alkyl sulfates, such as diethanolammonium lauryl sulfate; salts of alkylarylsulfonates, such as calcium dodecylbenzenesulfonate; alkylphenol/alkylene oxide addition products, such as nonylphenol ethoxylate; alcohol/alkylene oxide addition products, such as tridecylalcohol ethoxylate; soaps, such as sodium stearate; salts of alkylnaphthalenesulfonat.es, such as sodium dibutylnaphthalenesulfonate; dialkyl esters of sulfosuccinate salts, such as sodium di(2-ethythexyl)sulfosuccinate; sorbitol esters, such as sorbitol oleate; quaternary amines, such as lauryltrimethylammonium 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-alkylphosphate esters; as well as further substances known to the skilled in the arts.

[0536] Further adjuvants that can be used in herbicidal formulations include crystallization inhibitors, viscosity modifiers, suspending agents, dyes, anti-oxidants, foaming agents, light absorbers, mixing auxiliaries, antifoams, complexing agents, neutralizing or pH-modifying substances and buffers, corrosion inhibitors, fragrances, wetting agents, take-up enhancers, micronutrients, plasticizers, glidants, lubricants, dispersants, thickeners, antifreezes, microbicides, and liquid and solid fertilizers.

[0537] The compositions according to the invention can include an additive comprising an oil of vegetable or animal origin, a mineral oil, alkyl esters of such oils or mixtures of such oils and oil derivatives. The amount of oil additive in the composition according to the invention is generally from 0.01 to 10%, based on the mixture to be applied. For example, the oil additive can be added to a spray tank in the desired concentration after a 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, emulsified vegetable oil, 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. Preferred oil additives comprise alkyl esters of C.sub.8-C.sub.22 fatty acids, especially the methyl derivatives of C.sub.12-C.sub.18 fatty acids, for example the methyl esters of lauric acid, palmitic acid and oleic acid (methyl laurate, methyl palmitate and methyl oleate, respectively). Other oil derivatives are known to the skilled in the arts, for examples from the Compendium of Herbicide Adjuvants, 10.sup.th Edition, Southern Illinois University, 2010.

[0538] The herbicidal compositions generally comprise from 0.1 to 99% by weight, especially from 0.1 to 95% by weight, compounds according to this invention 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. The inventive compositions generally comprise from 0.1 to 99% by weight, especially from 0.1 to 95% by weight, of compounds of the present invention 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 may preferably be formulated as concentrates, the end user will normally employ dilute formulations.

[0539] The rates of application vary within wide limits and depend on the nature of the soil, the method of application, the crop plant, the pest to be controlled, the prevailing climatic conditions, and other factors governed by the method of application, the time of application and the target crop. As a general guideline, compounds may be applied at a rate of from 1 to 2000 l/ha, especially from 10 to 1000 l/ha. Preferred formulations can have the following compositions (weight %):

[0540] Emulsifiable concentrates: [0541] active ingredient: 1 to 95%, preferably 60 to 90% [0542] surface-active agent: 1 to 30%, preferably 5 to 20% [0543] liquid carrier: 1 to 80%, preferably 1 to 35%

Herbicidal Activity

[0565] In various embodiments, the invention provides compounds and compositions, including any embodiment described herein, for use in any of the methods of this invention. In various embodiments, use of a compound of this invention or a composition comprising the same, will have utility in inhibiting, suppressing, enhancing, or stimulating a desired response, as will be understood by one skilled in the art. In some embodiments, the compositions may further comprise additional active ingredients, whose activity is useful for the particular application for which the compound of this invention is being administered.

[0566] The compounds of this invention are useful as herbicides or herbicidal compounds. The present invention therefore further comprises a method for controlling the growth of undesired plants, comprising applying to the plants or a locus comprising them, an effective amount of a compound according to this invention, or an agrochemical composition thereof, under conditions effective to control the growth of the undesired plants, in particular the growth of weeds, in crops of useful plants.

[0567] In some embodiments, “Controlling” according to this invention refers to killing, reducing or retarding growth or preventing or reducing germination. Generally, the plants to be controlled are unwanted plants (weeds).

[0568] In some embodiments, “Locus” refers to the area in which the plants are growing or will grow.

[0569] The rates of application of compounds of the invention may vary within wide limits and depend on the nature of the soil, the method of application (for example: pre-plant, pre-emergence; post-emergence; application to the seed furrow; no tillage application etc.), the crop plant, the weed(s) 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 the invention are generally applied at a rate of from 10 to 2000 g/ha, especially from 50 to 1000 g/ha.

[0570] In some embodiments, the application is made by spraying the composition, typically by tractor mounted sprayer for large areas, but other methods such as dusting (for powders), drip or drench can also be used.

[0571] In some embodiments, useful plants in which the composition according to the invention can be used upon include crops such as cereals including but not limited to barley and wheat, cotton, oilseed rape, sunflower, maize, rice, soybeans, sugar beet, sugar cane and turf.

[0572] In some embodiments, crop plants also include trees, such as fruit trees, palm trees, coconut trees or other nuts. Also included are vines such as grapes, fruit bushes, fruit plants and vegetables.

[0573] In some embodiments, the crops are resistant crops. Therefore, according to some embodiments, crops also include those crops which have been rendered tolerant to herbicides or classes of herbicides (including but not limited to: ALS-, GS-, EPSPS-, PPO-, ACCase- and HPPD-inhibitors) by conventional methods of breeding or by genetic engineering. Examples of crops that have been rendered tolerant to herbicides by genetic engineering methods include but not limited to glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady® and LibertyLink®. According to other embodiments, crops also include those which have been rendered resistant to harmful insects by genetic engineering methods, examples of such crops include but not limited to: Bt maize (resistant to European corn borer), Bt cotton (resistant to cotton boll weevil) and Bt potatoes (resistant to Colorado beetle). Non limiting examples of Bt maize include the Bt 176 maize hybrids of NK® (Syngenta Seeds). Non limiting examples of transgenic plants comprising one or more genes that 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 or seed material thereof can be both resistant to herbicides and, at the same time, resistant to insect feeding (“stacked” transgenic events).

[0574] In some embodiments, crops include those which are obtained by conventional methods of breeding or genetic engineering and contain so-called output traits (e.g. improved storage stability, higher nutritional value and improved flavour). Other useful plants include turf grass for example in golf-courses, lawns, parks and roadsides, or grown commercially for sod, and ornamental plants such as flowers or bushes.

[0575] Herbicidal compounds, or chemically active herbicides, may be broken down into pre-plant herbicides, pre-emergent herbicides and post-emergent herbicides. Pre-plant and pre-emergent herbicides typically interfere with germination of weed seeds and are applied before and after planting or sowing, respectively, but before seed germination, whereas post-emergent herbicides kill the weeds after the weed seeds have germinated and weed growth has begun.

[0576] When administering the compounds of the present invention, they can be administered in pre-plant or pre-emergence treatments, in post-emergence treatments, or both.

In each pot, 10-15 seeds were sowed according to the specie viability. Timing of application determined at a 1-2 true leaf stage. The plants grew for 30 days in a controlled greenhouse (26±2° C. day, 20±2° C. night). Hood irrigation (tap water+Shefer 5:3:8 8 mM) was given at a 50% water content by weight. Two days before application, the tested plants thinned down to three plants per pot. Compounds were soluble in water (DDW), and commercial herbicide control was soluble in formulation B (Table 4). Before application, 1% (v/v) crop oil and 0.02% (v/v) surfactant (Tergitol™ 15-S-7) were added to the solution. Application was conducted with an industrial sprayer (TeeJet 6502E nozzle) at a rate of 2 kg/ha and spray volume of 4801/ha. Plants were evaluated at 3 time points (4, 8, 12 days after application (DAA)). At each time point, visual phenotyping was recorded using a scale of 0-6 (0: no visible effect, 6: maximum effect). At 12 DAA, plants foliage was harvested, dried and weighed for dry weight analysis.

In-Planta High Through-Put Screens (HTPS) Results

Post-Emergence Applications on Miniature Dicot Model Plants

[0636] Arabidopsis thaliana seeds were sown in 96 well plates filled with irrigated Sweet sand (10%>clay) that is washed from salts and minerals using tap water. 5-10 seeds were sown in the center of each well. 7-8 days post sowing, at 2 true leaves stage, thinning out was performed to ensure that compound application is done on a single plant per well. The plates were placed in a controlled greenhouse in a random order inside a bath which allows flooding irrigation with tap water supplemented with a fertilizer. Applied compounds were dissolved into a final solution of 50% acetone, 49.9% DDW, 0.1% tween-20.

[0637] A 96 well plate was used as a stock plate for preparing application solutions for 8 repeats. Each row contained different concentrations per chemical. Maximal concentration for application was 1.5 Kg/Ha and dilution factor is 2.5. Chemical application was performed one day after thinning out in a chemical hood. 5 L applied on first two true leaves in each well using 12 channel pipettes. Data collection: RGB (red, green, blue) data for green area per well was documented using camera. Data is collected at a few time points during the experiment: one day after thinning and before chemical application, two-, six- or nine-days post application. During the last two documentations, visual phenotyping was performed. Data analysis: Given RGB results and visual phenotype scores, a student t-test conducted to compare between treatment and control performance for continuous data (RGB) and Fisher exact test to analyze the non-continuous data (phenotypic scores). Dose-Response curves are generated for each treatment to infer ED.sub.50 and max. inhibition parameters, using treatment's log concentration range as the dependent variable and normalized green area.

Pre-Emergence Applications on Dicot and Monocot Model Plants

[0638] These experiments are conducted similarly except that either Arabidopsis thaliana or Eragrostis teff seeds were sowed (5-10 or 5-7, respectively), plant thinning out was not performed, compound dissolved into a final solution of 50% acetone, 49.9% DDW, compound application was done at 30 L volume per well directly on sowed soil before plant emergence and data was collected 10 or 7 days after chemical application on dicot or monocot plants, respectively.

Imaging, RGB and Statistical Analysis

[0639] Plate imaging performed at 11 and 18 DAA. RGB data for green area per well was documented and used to extract % inhibition. Dose-Response curves were built for each treatment to infer EC50, EC75 and EC90 parameters, using treatment's log concentration range as the independent variable and normalized green area as the dependent variable. Treatments were compared to controls performance given RGB results and using student's t-test (p-val≤0.05).

Results:

[0640] Compounds 104-154 were applied in either or both pre- and post-emergence mode to either or both monocot and dicot model plants, following the methods described above. The compounds were applied as a gradient of concentrations as listed above, from which the ED.sub.50 was calculated.
