Pyrazole derivatives useful as a herbicidal component

Abstract

A pyrazole derivative having the formula (I): ##STR1## wherein X.sub.1 and X.sub.2 are respectively a (C.sub.1 -C.sub.4) alkyl group, Y is a halogen atom, nitro group, acetyl group, cyano group, or a phenoxy group which may be substituted with one or more halogen atoms, l is an integer of 1 to 3, and Z is a (C.sub.1 -C.sub.4) alkyl group, a (C.sub.2 -C.sub.4) alkenyl group, a (C.sub.2 -C.sub.4) alkynyl group, acetylmethyl group, an aralkyl group in which the aryl moiety thereof may be substituted with one or more nitro groups, a phenacyl group in which the phenyl moiety thereof may be substituted with one or more halogen atoms, one or more nitro groups, one or more (C.sub.1 -C.sub.4) alkyl groups, one or more (C.sub.1 -C.sub.4) alkoxy groups, one or more (C.sub.1 -C.sub.4) alkylthio groups, acetyl group, acetylamino group, cyano group, methylsulfonyl group, phenoxy group or phenyl group; a dinitrophenyl group, or a thenoylmethyl group in which the cyclic moiety thereof may be substituted with one or more halogen atoms or one or more (C.sub. 1 -C.sub.4) alkyl groups, which is useful as a herbicidal component in paddy fields.
