FIELD: chemistry.
SUBSTANCE: invention relates to the synergistic herbicide composition, containing the herbicide effective amount of (a) the formula compound (I):
or its agriculturally acceptable salt or compound ether and (b) clomazone or its agriculturally acceptable salt, carboxylic acid, carboxylate salt, or the ether. (a) and (b) are presented in such the proportion, that the composition exhibits the herbicide synergism, where the ratio between (a) and (b) is from about 1:3 up to about 1:84. The invention relates to the method of the undesirable vegetation inhibition by bringing into contact the plant, that is the undesirable vegetation, or its locus, soil or water, where soil or water allows the growth of the undesirable vegetation, with the herbicidally effective amount of the composition, containing (a) the formula compound (I) or its agriculturally acceptable salt or ether, and (b) clomazone or its agriculturally acceptable salt, the carboxylic acid, the carboxylate salt or ether. (a) and (b) are presented in the composition in such a proportion, that the composition exhibits the herbicidal synergism, wherein the ratio between (a) and (b) is from about 1:3 to about 1:84.
EFFECT: increase of the composition efficiency.
