Herbicidal 4,5-dihydro-1H-1,2,4-triazole-3-carboxamide derivatives are represented by the formula (I):
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; X¹ represents a halogen atom or an alkyl group having from 1 to 3 carbon atoms; X² represents hydrogen atom, a halogen atom or an alkyl group having from 1 to 3 carbon atoms; Y¹ represents a hydrogen atom or fluorine atom; and Y² represents a hydrogen atom or fluorine atom.

Disclosed herein is a 4,5-dihydro-1H-1,2,4-triazole-3-carboxamide derivative represented by the formula (I): ##STR1## wherein R represents a straight-chain alkyl group having 1 to 10 carbon atoms which is non-substituted or substituted with 1 to 19 fluorine atoms or a branched alkyl group having 3 to 10 carbon atoms which is non-substituted or substituted with 1 to 19 fluorine atoms; X.sup.1 represents a halogen atom or an alkyl group having 1 to 3 carbon atoms; X.sup.2 represents hydrogen atom, a halogen atom or an alkyl group having 1 to 3 carbon atoms; Y.sup.1 represents hydrogen atom or fluorine atom; and Y.sup.2 represents hydrogen atom or fluorine atom. The derivatives of the formula (I) have high herbicidal activities and also show a excellent selectivity in their actions for killing weeds alone while doing any practical harm to the crops such as rice, wheat and corn.
