Abstract: This invention relates to herbicidal compositions containing sulfonylureas useful for control of undesired vegetation by treatment of vegetation or the locus to be protected. To eliminate detrimental effects of herbicides in crop rotation and phytotoxicity to crops by lowering dosage and widening of activity spectrum a novel herbicidal composition is disclosed consisting of diethylethanolammonium salts of 1-(2-chlorobenzenesulfonyl)-3-(4-isopropylydeniminoxy-6-dimethylamino-1,3, 5-triazin-2-yl)urea and 1-(2-substituted-benzenesulfonyl)-3-(4-methoxy-6-methyl-1,3,5-triazin-2-yl )urea (e.g. chlorsulfuron and triasulfuron derivatives), a surfactant, an organic solvent and water.

Abstract: This invention is related to herbicidal compositions comprising derivatives of benzenesulfonylurea and 2-methoxy-3,6-dichlorobenzoic acid for control of undesired vegetation by treating said vegetation and locus to be protected by said compositions.To eliminate the detrimental effects on crop rotation by lowering dosage of herbicide and to widen its activity spectrum a herbicidal composition is proposed comprising a mixture of ammonium salts of benzenesulfonylurea derivatives and of 2-methoxy-3,6-dichlorobenzoic acid with additives.The treatment of the vegetation and locus is performed by water solution of the disclosed composition with the dosage in the range of 50-500 g/ha of composition.
