The invention relates to chemical means of plant protection, intended for the destruction of weeds in cereal crops, particularly to a solid herbicide composition on the basis of 2-methoxy-3,6-dichlorobenzoyl acid (dicamba) and such derivatives benzosulfimide as chlorsulfuron, metsulfuron, tribenuronmethyl and chlorsulfuron.

Known liquid herbicide formulations in the form of water or water-glycol solutions containing as active ingredients salt dicamba and sulfonylurea derivatives (See, for example, the patents of the Russian Federation№2040179, №2106782, №2208930, №2236134).

The active components of these formulations are widely known (See. LNB and other "Pesticides and plant growth regulators Handbook, M. "Chemistry", 1995):

Dicamba-2-methoxy-3,6-dichlorobenzene acid, p.66;

Chlorsulfuron-3(6-methyl-4-methoxy-1,3,5-triazinyl-2)-1-(chlorophenylsulfonyl)urea, str;

Metsulfuron-methyl - methyl ester 2-[3-(6-methyl-4-methoxy-1,3,5-triazine-2-yl)aridoculture)benzoic acid, pg.107;

Tribenuron-methyl - methyl ester 2-[3-(4-methoxy-6-methyl-1,3,5-triazine-2-yl)-3-methylenedioxyphenyl)benzoic acid, PP 156;

Chlorosulfonyl-3-[4-dimethylamino-6-(α-methylethylenediamine-1,3,5-triazine-2-yl)]-1-2-chlorobenzenesulfonyl)urea, str.

The disadvantage of liquid formulations of herbicides, aderrasi as active substances a mixture of dicamba and derivatives benzosulfimide, is the low stability during storage. Over time, the drugs lose their effectiveness due to hydrolysis of the sulfonylurea, the speed of which is increased in the presence of 2-methoxy-3,6-dichlorobenzoyl acid.

So, chlorsulfuron hydrolyzed in water at 20°C and a pH of 5.7-7.0 on 50% within 4-8 weeks. Metalformer hydrolyzed in water at 25°C and pH 5 for 33 days, and at pH 7 in 6-8 weeks. Tribenuronmethyl rapidly hydrolyzed at t° 45°C pH 7, unstable in most organic solvents (The Pesticide Manual. Twelf Edition, 2000, str, 644, 928). Chlorsulfuron hydrolyzed at pH 7 and t° 22°within 30 days (NN. Melnikov. "Pesticides and plant growth regulators". Handbook, M.; "Chemistry", str).

The most stable of well-known liquid preparations based on dicamba and chlorsulfuron is Dipesan®*(*A registered trademark of VNIIHSZR) BP (RF patent No. 2106782).

As for the compositions according to the patent No. 2040179, in particular drug Cowboy, to prevent decomposition or reduction of the rate of decomposition during storage and transport him to be released into the original binary package, i.e. separately chlorsulfuron in the form of a 12.5%aqueous-glycolic solution (Drug 1) and separately dicamba in the form of a 48%aqueous solution of salts with dimethylamine (Banvel-D). Re the use of components were mixed and diluted with water to the desired concentration (Protection and quarantine of plants" No. 4, 1996, p.14-15).

In the description of the invention to the patent of Russian Federation №2040179 given herbicide composition containing as active ingredients dimethylammonium salt dicamba (I), diethylethanolamine salt chlorsulfuron (II) and diethylethanolamine salt chlorsulfuron (III). Herbicide composition 1.3 also contains Diethylaminoethanol, triethylene glycol and water in the following ratio of components, wt %:

On acid equivalents
Dimethylammonium salt dicamba (I)10-508,3-41,5
Diethylethanolamine salt chlorsulfuron (II)1-70,75-5,25
Diethylethanolamine salt chlorsulfuron (III)2-141,56-10,5

The ratio between the amounts of active substances, salts I:II:III=(1,5-50):1:2, on acid equivalents I:II:III=(1,6-55):1:2 (the Prototype).

This composition is unstable during storage and insufficient when it is used for the suppression and destruction of weeds in crops of C is nowych cultures. As shown in the description of the patent of the Russian Federation No. 2040179 experiments (see table No. 7 on page 15-16), the active components of the composition do not show in vegetation experiments combined, synergistic effects in relation to suppress the growth of weeds.

FIELD: agriculture.

SUBSTANCE: synergetic herbicide composition contains active substances such as chlorimuron-ethyl (I) and imazetapir (II) and salts thereof, used in the ratio of (I):(II)-10:1, and also contains fillers, diluents, surfactants and other functional additives needed for producing of preparation forms. Method for controlling of weed plants in sown farm crops involves using effective doses of preparations adapted for suppressing weed plants without affecting leguminous crops such as soya, feed beans, pea etc.

EFFECT: wider range of weed plant controlling means and processes.

FIELD: organic chemistry, herbicides.

SUBSTANCE: invention describes a herbicide agent comprising (a) herbicide active substance representing sulfonylurea of the formula (I): and/or its salts; (b) silicone surfactant chosen from the group of polyalkylene oxide-modified copolymers of dimethylpolysiloxane of the general formula: , and (c) wetting agent comprising lactic acid and its derivatives with the synergistically effective content of herbicide (a) with surfactant (b) and wetting agent (c). Also, invention describes a method for control of weeds by using the proposed herbicide agent. Proposed herbicide agent shows the excellent herbicide impact with synergetic effect.

EFFECT: improved method for weed control, enhanced and valuable properties of herbicide.
