METHODS OF ENHANCEMENT OF HERBICIDE ACTIVITY, HERBICIDE COMPOSITIONS WITH ENHANCED ACTIVITY, COMPOSITION FOR ENHANCEMENT OF ACTIVITY OF HERBICIDE COMPOSITION Russian patent published in 2000 - IPC

FIELD: organic chemistry, agriculture, herbicides. SUBSTANCE: invention describes method of enhancement of activity of herbicide composition containing N-[(4,6-dimethoxypyrimidine-2-yl)-aminocarbonyl] -3-dimethyl-aminocarbonyl-2-pyridine sulfonamide, methyl-2-[[[4,6-bis-(difluoromethoxy)-pyrimid-2-yl] aminocarbonyl]aminosulfonyl]- benzoate or their salt as active herbicide component of sulfonylurea type. Method involves the use of surface-active substance of ethoxylated saturated amine type and vegetable and/or mineral oil and surface-active substance of ethoxylated saturated amine type is taken among the group consisting of animal or plant ethoxylated amines, for example, from animal fat, soybean and coconut oil at mean content of ethylene oxide in indicated surface-active substance 5-20 moles. Invention describes also herbicide compositions, composition for enhancement of activity of herbicide composition. EFFECT: enhanced activity of herbicide composition, simplified method and use. 23 cl, 18 tbl, 91 ex
