Abstract
Disclosed herein is a derivative of 1,5-diphenyl-1H-1,2,4-triazole-3-carboxamide represented by the formula (I): ##STR1## wherein R is a straight-chain alkyl group having 1 to 10 carbon atoms which is non-substituted or substituted with 1 to 19 fluorine atoms, a branched alkyl group having 3 to 10 carbon atoms which is non-substituted or substituted with 1 to 19 fluorine atoms, a cyclic alkyl group having 3 to 10 carbon atoms, an alkyl group having 1 to 3 carbon atoms which is substituted with an alicyclic structure having 3 to 7 carbon atoms, a phenyl group or an aralkyl group having 7 to 9 carbon atoms; X.sup.1 is a halogen or an alkyl group having 1 to 3 carbon atoms; X.sup.2 is a hydrogen, a halogen or an alkyl group having 1 to 3 carbon atoms; Y.sup.1 is a hydrogen or a fluorine; and Y.sup.2 is a hydrogen or a fluorine, and the herbicidal compositions containing said derivatives as active ingredient therefor. The derivative of 1,5-diphenyl-1H-1,2,4-triazole-3-carboxamide represented by the formula (I) of the present invention is the compound having high herbicidal activity and also showing excellent selectivity for killing weeds alone without doing any serious harm to the crops such as rice, wheat and corn.
