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.
本发明旨在提供一种新型的N-取代-3-(取代肼基)苯磺酰胺衍生物,以及一种含有除草有效量的该衍生物的除草组合物。N-取代-3-(取代肼基)苯磺酰胺衍生物由式(I)表示:
其中 R1 是 C1-C4 烷基、一氯甲基、C3-C4 烯基、C1-C4 烷氧基甲基、C1-C4 烷氧基羰基、C1-C4 烷硫基乙基、吡啶基、噻吩基、炔基、四氢糠基、吗啉基或未取代或被氯或 C1-C4 烷基取代的苯基;R2 是氢或 C1-C4 烷基;R3 是 C1-C4 烷基;X1 是 C1-C3 烷基、C1-C3 烷氧基或氯;X2 是 C1-C3 烷基或 C1-C3 烷氧基;Z 是 N 或 CH。
