The invention can be used in agriculture to combat long-soboliferous and broadleaf weeds in cereal crops.

Known herbicide composition in the form of an aqueous-glycolic solution based diethylethanolamine salt chlorsulfuron and dimethylammonium salts 2-methoxy-3,6-dichlorobenzoyl acid (dicamba)containing 17.5 g/l of chlorsulfuron and 368 g/l dicamba [List of pesticides and toxic chemicals permitted for use on the territory of the Russian Federation. M., 2003, s].

Known herbicide composition in aqueous solution based on diethylethanolamine salts dicamba and chlorsulfuron containing 344 g/l dicamba and 18.8 g/l of chlorsulfuron [List of pesticides and toxic chemicals permitted for use on the territory of the Russian Federation. M., 2003, s].

Known Energeticheskiy herbicide composition for use in cereal crops, including ammonium salt benzosulfimide and dicamba, surfactant, triethylene glycol and water [RF Patent №2040179].

Lack of ethicsaction is a low chemical stability sulfonylureas due to its hydrolysis, especially in the presence of water, which helps reduce herbicide activity of the composition.
