SUBSTANCE: invention relates to herbicide composition, containing conventional inert additives and mixture of a) herbicidically effective amount of substance satisfying the formula I [in formula R₁ and R₃ are the same or different C1-C4-alkyl; R₄ and R₅ together form groups of formulae: -C-R₆(R₇)-O-C-R₈(R₉)-C-R₁₀(R₁₁)-C-R₁₂(R₁₃)-(Z₁), -C-R₁₄(R₁₅)-C-R₁₆(R₁₇)-O-C-R₁₈(R₁₉)-C-R₂₀(R₂₁)-(Z₂), or -C-R₂₂(R23)-C-R₂₄(R₂₅)-C-R₂₆(R₂₇)-O-C-R₂₈(R₂₉)-(Z₃), wherein each R_6-R₂₉ is hydrogen; G is hydrogen or -C(X₂)-X₃-R₃₁; X₂ and X₃ independently are oxygen; R₃₁ is C1-C10-alkyl]; b) herbicidic synergic amount of at least one herbicide selected from group containing sulfonylureas, phenoxyacetic acids, as well as florsulam, tralcoxidim, klodinafol-propargil, phenoxaprop-P-ethyl, trifluramine, pendimethaline, picolinafen, etc. Composition also may contain safety effective amount of protective agent, such as chloquintocet-mexyl and additive (e.g., mineral oil or C8-C22-fat acid alkyl esters) in amount of 0-2 mass %. Also disclosed is method for selective controlling of weeds and grassy plants in cultural plants by treatment of cultural plants, seeds or seedlings thereof, or vegetation area thereof with claimed composition.

EFFECT: effective composition and method for weed controlling.
