The invention relates to herbicides that can be used for combating weeds in crops, and more specifically to a new synergistic herbicide compositions and method of weed control by processing agricultural crops an effective amount of the composition.

Known herbicide product from the group of the sulfonylureas "classic" (a trademark of DuPont"), the active ingredient of which is chlorimuron-ethyl, compound of formula I

Ethyl ester of 2-[[(4-chloro-6-methoxypyridine-2-yl)aminocarbonyl]aminosulfonyl] benzoic acid and its suitable for processing agricultural crops salt.

Chlorimuron-ethyl effective against many species of plants and can be used both for continuous and for selective destruction of unwanted vegetation (U.S. Patent No. 4547215, patent USSR No. 1215603).

Widely known imidazolinone herbicides, including imazethapyr (the active ingredient of the drug, "Pivot" (Trade mark Company American Cyanamid company), a compound of formula II.

(R,S)-5-ethyl-2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)nicotinic acid and its salts, suitable for use in agriculture (U.S. Patent No. 4608079, No. 4798619, EP 0041623, Patent USSR No. 1780498).

In subsequent years there has been a significant amount of mixed preparations containing either chlorimuron-ethyl, or imazethapyr in combination with other herbicides. So DuPont recommends for combating weeds in crops of soya, two mixed drug Canopy SP®(chlorimuron-ethyl + metribuzin) and Canopy XL®(chlorimuron-ethyl + sulfentrazone). Cm. Proprietary materials "Font Du Canopy®SP" and "Du Pont Canopy®XL", "Du Pont agricultural products, 1988".

In the European patents EP 0181830 and EP 0187221 described synergistic compositions containing chlorimuron-ethyl and similar in structure derivative teruhiko-2H-isoindole-1,3-dione. In EP 1470763 described herbicide composition containing chlorimuron-ethyl and its salts in combination with derivatives of uracil.

In the patent of Russian Federation №2245621 described a synergistic combination of herbicides containing N-[N-(4,6-dimethoxypyrimidine-2-yl)-aminocarbonyl-2-(dimethylaminoethyl)-5-(formylamino)benzosulfimide and imazethapyr. The mixing ratio from 1:1 to 1:3. The mixture is recommended for weed control in crops as maize varieties that are resistant to glufosinate or glyphosate, or those of soybean crops that are resistant to imidazolinones.

The disadvantages of this herbicide combination is phytotoxicity with respect to cultural the plants (soy, corn)that must be overcome by adding antidotes, and low efficiency in relation to some grass and perennial weeds.

The closest analogue of the invention is described in U.S. patent No. 5478795 herbicide composition containing chlorimuron-ethyl and imazapyr (isopropyl-ammonium Sol-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)nicotinic acid), the active ingredient of the herbicide Arsenal (Trade mark Company American Cyanamid company"), is recommended for continuous destruction of vegetation on the land for non-agricultural purposes. For selective destruction of weeds in agricultural crops the preparation is not used. As described in the above patent indicators, combination chlorimuron-ethyl and imazalil in soybean herbicide has activity only against morning glory (Pitted Morningglory), and in relation to other weeds it is not effective. In higher doses, this mixture cannot be applied due to the high phytotoxicity relative to cultivated plants, including soy.

The object of the present invention is a synergistic herbicide composition containing chlorimuron-ethyl (I) and imazethapyr (II)and their salts suitable for processing agricultural kulturu the context of this invention, the term "salt, suitable for processing of agricultural crops" includes salts of alkaline and alkaline-earth metals, ammonium, Quaternary ammonium salts, alkyl diethanol-, dialkyl-ethanol - and triethanolammonium salt. When sharing these herbicides observed a synergistic effect, i.e. the combined effect of I+II is more effective than the sum of the actions of the individual herbicides. This allows you to reduce the rates of consumption and reduce environmental burden in the treated crops and soil. A synergistic effect occurs when the ratio of I:II is from 1:10 to 10:1, preferably from 1:4 to 4:1.

The composition in accordance with the present invention suppresses or destroys depending on consumption rates and the degree of sensitivity of plants such weed plants in crops of legumes (soybeans, broad beans, peas and others), as wild oats, millet, chicken, akalifa South, ragweed, Shandra comb, amaranth thrown back, Alopecurus, weed, ryegrass, barnyard grass, mint, syt, the onion, amaranth, white pigweed, lady's bedstraw, sow Thistle yellow, pink sow Thistle, dead-nettle, morning glory, Highlander pochechuynogo, Highlander vjunkovye, sigesbeckia fluffy, mustard, nightshade, starwort, Veronica, violet, cocklebur, bindweed, Thistle, sorrel, tarragon, and others.

The application rate of herbicide composition during the processing of crops above Bo the new cultures the amount of active substances is from 20 to 90 g/ha

The composition may be used for treatment of plants or their habitats in the form of so-called tank mixes, prepared immediately before use, and ready preparative forms, which is certainly more convenient and therefore preferred.

Suitable for a given combination of herbicides are, for example, such formulation, as soluble and wettable powders, concentrates, emulsions, emulsions of the type oil-in-water or water in oil, dispersions on an oil or water based, suspoemulsions, suspension concentrates, granules, including water-soluble and modedesignerin, water and water-glycol solutions, water-soluble concentrates.

Wettable powders are uniformly dispergirujutsja in water preparations, which, together with the active substances contain a filler, usually inert substance, wetting agent, for example ethoxylated or propositionally ALKYLPHENOLS, polyoxyethylene aliphatic alcohols or amines, sulfates or phosphates polyoxyethylenated fatty alcohols, alkanesulfonyl or alkylarylsulfonate and a dispersant, such as lignosulfonates in the form of salts, condensed alkylnaphthalene, 2,2-dynafilter-6,6-disulfonate sodium, dibutylaminoethanol sodium or aermet laurinavicius sodium, phosphates or sulfates ethoxylated or propoxycarbonyl of christianperon, derivatives sulfosuccinates and alkylacrylate.

Mulgirigala concentrates are obtained by dissolving the active substance in an organic solvent such as aliphatic alcohols, cyclic ketones, dimethylformamide, aromatic hydrocarbons, including high-boiling, high-boiling aliphatic hydrocarbons, isophorone, various oils, both mineral and vegetable with the addition of emulsifiers. As emulsifiers can, for example, be used anion active surfactants, such as alkyl(aryl)sulfonates, including calcium dodecylbenzenesulfonate and nonionic surfactants, such as polyglycolide ethers of fatty alcohols, polyglycolide esters of fatty acids, condensation products of ethylene oxide and propylene (block copolymers), alkylpyridine, esters of fatty acids sorbitan, esters of fatty acids of polyoxyethylenesorbitan or esters polyoxyethylenesorbitan acid.

The emulsion of the type oil-in-water" or "water in oil" may contain the above-listed solvents, water and in addition to the above emulsifiers also phosphates or sulfates ethoxylated derivatives of alkyl(di -, or three-styryl)phenols and ethoxylated derivatives of alkyl(di -, or three-styryl)phenols. The composition of the aqueous emulsions of the discrepancies between the data types are also thickener, defoamer and anti-freeze.

Granules can be obtained by applying active substances in granular inert carriers with high sorption capacity, sometimes with the addition of adhesive components, such as polyvinyl alcohol, polyacrylate, mineral oil. You can get pellets prepared from mixtures of active substances with inert fillers, dispersing agents, wetting, antispywares and other auxiliary substances a variety of known methods of granulation.

Suspension concentrates produced by milling a mixture of active ingredients with excipients (dispersing agents, wetting, antispyware and others) on bead mills to achieve dispersion of the particles less than 5 microns with the following formulation by adding thickeners and stabilizers viscosity.

Another object of the invention is a method of combating weeds in crops of cultivated plants, preferably legumes (soy, beans, peas), namely, that a synergistic herbicide composition consisting of chlorimuron-ethyl and imazethapyr and/or their salts, applied in effective amounts to be suppression or destruction of weeds or their habitat.

If necessary patented herbicide composition m which can be used together with other known herbicides, such as 2,4-D, 2M-4, dicamba, triazine herbicides and other by joint or sequential processing of these drugs clogged undesirable plants crops.

Examples of obtaining various preparative forms and their characteristics, and biological examples for the assessment of herbicide activity patent-pending synergistic herbicide composition. The examples illustrate but do not limit the present invention.

Biological tests

P is the iMER 10

Initial assessment of herbicide activity of mixtures chlorimuron-ethyl and imazethapyr with different ratios of components were performed in the laboratory of artificial climate during the next operation mode of the camera: the duration of the day, 16 hours, night - 8 hours illumination in the daytime - 15000 Lux, temperature - 20°C, relative humidity of 75%, the duration of the experience - 30 days. As a model grass weeds used the test plants of spring wheat (Triticum aestivum) and millet seeds (Panicum mileaceum L.). For processing test-plant herbicides used experimental sprayer configured as close as possible to production mode by the following indicators: the rate of flow of the working fluid, the uniformity of its distribution in the treated area, the degree of dispersion of the droplets.

The test plants were treated with the rate of fluid flow 400 l/ha, the average size of the droplets 180±20 μm (see "Chemistry in agriculture", 1985, No. 7).

There were two variants of the experiments. The first treatment of the test plants in phase 2 of the leaves, the second processing test plants in phase 4 leaves, the repetition of experiments in each case up to 4 times. Accounting was performed 21 days after treatment compared to untreated control.

In the first variant was determined dose equivalent for various ratios of chlorine what he is ethyl and imazethapyr from 1:10 to 10:1, required for growth inhibition 80% of test plants (U80). The results are presented in the form of diagrams (figure 1 and 2). On the y-axis of the applied dose chlorimuron-ethyl on the x - axis dose imazethapyr. The obtained curves are below the straight line connecting the doses of the individual components, which clearly indicates the presence of a synergistic effect (see Roberts H.A., ed. - "Weed Control Handbook.Principes" 7thed., Blacwell Sci. PubL, 1982. p.232-235 "The Evaluation of a new herbicide").

In the second embodiment, the synergism was calculated by the Colby formula (see S.R.Colby, Weeds. "Calculating Synergistic and Antagonistic response of herbicide combination", v.15, pp.20-22, 1967):

where- % inhibition of component A;
