4,5-Dihydro-1H-1,2,4-triazole-3-carboxamide derivatives and herbicidal composition containing the same.

摘要

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