The invention can be used in agriculture to control weeds in crops of cereals.

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 agrochemicals 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 agrochemicals permitted for use on the territory of the Russian Federation. M., 2003, s].

The dose of the herbicide 80 g/ha Efficacy of the herbicides evaluated by weight of weeds for experimental and control plots in the phase of earing. A record harvest is carried out by continuous threshing wheat. Square plots of 10 m2the repetition is fourfold. NDS 095 considering harvest ±0.4 t/ha

The data in table 1 show that the composition (examples 1-10) gives a stable aqueous solution, whereas the prototype (the reamers 11, 12) forms an unstable suspoemulsions emitting coagulate, which contributes to an uneven distribution of the herbicide on the treated surface.
