摘要

Herbicidal derivatives of 1,5-diphenyl-1H-1,2,4-triazole-3-carboxamide are represented by the formula (I): <CHEM> wherein R is a straight-chain alkyl group having from 1 to 10 carbon atoms which is unsubstituted or substituted by from 1 to 19 fluorine atoms, a branched alkyl group having from 3 to 10 carbon atoms which is unsubstituted or substituted by from 1 to 19 fluorine atoms, a cyclic alkyl group having from 3 to 10 carbon atoms, an alkyl group having from 1 to 3 carbon atoms which is substituted with an alicyclic structure having from 3 to 7 carbon atoms, a phenyl group or an aralkyl group having from 7 to 9 carbon atoms; X<1> is halogen or an alkyl group having from 1 to 3 carbon atoms; X<2> is hydrogen, halogen or an alkyl group having from 1 to 3 carbon atoms; Y<1> is hydrogen or fluorine; and Y<2> is hydrogen or fluorine.
