FIELD: herbicides.

SUBSTANCE: invention relates to a herbicidal composition that can be used to control weeds in corn crops. The herbicidal composition for corn crops contains the following as active ingredients: terbutylazine, a sulfonylurea or a derivative thereof selected from nicosulfuron, rimsulfuron, iodosulfuron, iodosulfuron-methyl or iodosulfuron-methyl-sodium, 2,4-D or a derivative thereof and clopyralid or a derivative thereof. The ratio of the mixture of terbuthylazine, sulfonylurea or its derivative and 2,4-D or its derivative to clopyralid or its derivative is equal to (1-20):(1). As a derivative of 2,4-D, its 2-ethylhexyl ether, C₇-C₉ low-volatile ethers or dimethylamine salt are used. As a derivative of clopyralide, its 2-ethylhexyl ether, monoethanolamine salt or potassium salt are used.

EFFECT: proposed herbicidal composition for corn crops exhibits a synergistic herbicidal effect and enhanced action against weeds in corn crops with a reduced application dose.
