Herbicidal composition containing a derivative of 1,2,4-triazole as an

Abstract

Disclosed herein is herbicidal composition comprising a derivative of 1,2,4-triazole as an active ingredient, represented by the general formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom, a halogen atom or a C.sub.1 -C.sub.2) alkyl group; R.sup.2 represents a hydrogen atom, a halogen atom, a (C.sub.1 -C.sub.2) alkyl group fluoromethyl group (--CH.sub.2 F),3,3,3-trifluoropopyl group, methoxy group, cyano group, methoxymethyl group, methylthio group, methoxycarbonyl group or isopropoxycarbonyl group and R.sup.3 represents a thiocarbamoyl group or a group represented by the general formula (II): ##STR2## wherein R.sup.4 represents a hydrogen atom, a (C.sub.1 -C.sub.2) alkyl group or a hydroxy (C.sub.1 -C.sub.2) alkyl group and R.sup.5 represents a hydrogen atom, a C.sub.1 -C.sub.2) alkyl group, halogeno (C.sub.1 -C.sub.2) alkyl group, hydroxy (C.sub.1 -C.sub.2) alkyl group, cyanomethyl group, acetyl group, halogenoacetyl group, methoxyacetyl group, amino group, phenyl group, methoxy group, hydroxyl group, (C.sub.2 -C.sub.3) alkenyl group, halogeno (C.sub.2 -C.sub.3) alkenyl group, isopropylcarbonyl group, methylthiocarbamoyl group or 2-methoxyethyl group, the proviso that R.sup.2 is not a hydrogen atom, halogen atom or (C.sub.1 -C.sub.2) alkyl group when both of R.sup.4 and R.sup.5 represent hydrogen atoms, and herbicidally acceptable carrier(s) or diluent(s).
