SELECTIVE HERBICIDAL COMPOSITIONS AND METHODS FOR CONTROLLING OF UNDESIRED PLANTS IN TAME CULTURES Russian patent published in 2005 - IPC

FIELD: organic chemistry, agriculture.

SUBSTANCE: invention relates to selective herbicidal compositions, containing customary auxiliary substances, as well as: a) herbicidal effective amount of compound of formula I or agriculture acceptable salt thereof wherein R are independently C₁-C₆-alkyl, C₁-C₆-haloalkyl, C₁-C₄-alcoxy-C₁-C₄-alkyl, or C₁-C₄-alcoxy-C₁-C₄-alcoxy-C₁-C₄-alkyl; m = 2; Q is group of formula wherein R₂₃ is hydroxyl and Y is C₁-C₄-alkylen bridge; and b) synergetically effective amount of one or more herbicides; and methods for controlling of undesired plants in tame cultures using the said composition. Also disclosed is composition containing customary auxiliary substances, as well as herbicidal and synergetically effective amount of 4-hydroxy-3-(2-methyl-6-trifluoromethylpyridine-3-carbonyl)bicyclo[3.2.1]octo-3-ene-2-one of formula 2.2 and herbicidal antagonistically effective amount of antidote of formula 3.1. Compositions based on 4-hydroxy-3-(2-methyl-6-trifluoromethylpyridine-3-carbonyl)bicyclo[3.2.1]octo-3-ene-2-one and herbicidal antagonistically effective amount of antidote, as well as methods for controlling of weeds and cereal grasses in tame cultures also are described.

EFFECT: compositions useful in effective controlling of many weeds both in pre-spring and post-spring phases.
