The present invention is to provide a novel N-substituted-3-(substituted hydrazino)benzenesulfonamide derivative, and a herbicidal composition containing a herbicidally effective amount of the derivative. The N-substituted-3-(substituted hydrazino)benzenesulfonamide derivative is represented by the formula (I):
wherein R1 is C1-C4 alkyl, monochloromethyl, C3-C4 alkenyl, C1-C4 alkoxymethyl, C1-C4 alkoxycarbonyl, C1-C4 alkylthioethyl, pyridyl, thienyl, thenyl, tetrahydrofurfuryl, morpholino or phenyl which is unsubstituted or substituted with chlorine or C1-C4 alkyl; R2 is hydrogen or C1-C4 alkyl; R3 is C1-C4 alkyl; X1 is C1-C3 alkyl, C1-C3 alkoxy, or chlorine; X2 is C1-C3 alkyl or C1-C3 alkoxy; and Z is N or CH.
