HERBICIDAL COMPOUND AND WEED VEGETATION CONTROL METHOD Russian patent published in 2008 - IPC A01N47/36 A01N37/40 A01P13/00 

FIELD: agriculture.

SUBSTANCE: herbicidal compound containing as an active substance a synergically efficient mixture of the ammonium salt of the 2-methoxy-3,6-dichlorobenzoic acid (I) and ammonium salts of two herbicides from the row of substituted sulfonylureas (II and III), surfactants, glycol, and water. As the substituted sulfonylureas, chlorsulfuron (IIa) or tribenuron methyl (IIb) is used with metsulfuron methyl (III), the ratio I: (IIa or IIb): III being equal correspondingly to (19.0-19.3) : (1-3) : (0.68-2.1) according to acid equivalents. As surfactants the alkyldimethylamine oxide (ADMAO) or its mixture with synthanol BV or neonol 9-12, or polyoxyethylene ethers of fatty alcohols C₁₂-C₁₄ (ALM-10) is used, with the following ratios of the compound ingredients, wt %: ammonium salt of 2-methoxy-3,6-dichlorobenzoic acid according to the acid equivalent (ae) 27.0-38.0; ammonium salt of chlorsulfuron or tribenuron methyl (acc. to ae) 1.4-6.0; ammonium salt of metsulfuron methyl (acc. to ae) 0.95-4.2; surfactant 11-25; glycol 8.0 max; water being the remaining to 100.

EFFECT: invention allows to enhance product stability.
