FIELD: agriculture.

SUBSTANCE: herbicidal composition is described, containing a mixture of at least one of 2,4-dichlorophenoxyacetic acid ethers, such as ethyl, isopropyl, butyl, isobutyl, 2-ethylhexyl, and octyl, with at least one of such phosphoric or phosphorous acid ethers as tributyl phosphate, diethyl phosphate, triphenyl phosphate, bis(2-ethylhexyl) phosphate, ethyl phosphate, tris(butoxyethyl) phosphate, triisobutyl phosphate, diethyl phosphite, or dibutyl phosphite. A method of undesirable vegetation control is also described. The formulations suitable for this composition are emulsifiable concentrate, "oil in water" or "water in oil" emulsions, and microemulsions. The ratio of amounts of the 2,4-D ethers and phosphor-based acid ethers is 1:0.9 to 1:0.036, in conversion to the 2,4-D acid.

EFFECT: higher efficiency against weed plants in grain crops.
