The present invention provides indan-1,3-dione derivatives, including derivatives represented by the following formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom or a lower alkyl group; R.sup.2 represents a group represented by ##STR2## wherein E represents a (substituted) phenyl group or a (substituted) pyridyl group; Y represents a hydroxyl group; and Z represents a halogen atom, a (substituted) alkylsulfonyloxy group or a (substituted) phenylsulfonyloxy group, or Y and Z are bonded to represent --O--; and A represents a (substituted) 1,3-butadienylene group or a (substituted) 1,3-azabutadienylene group, and a herbicidal composition containing the same as an active ingredient. The compound of the formula (I) shows high herbicidal activity against gramineous weeds, cyperaceous weeds, etc. but shows markedly low phytotoxicity against crops.
本发明提供了吲哚酮衍生物,包括以下式子(I)所代表的衍生物:##STR1## 其中,R1代表氢原子或低碳基;R2代表由以下式子所代表的基:##STR2## 其中,E代表取代的苯基或取代的吡啶基;Y代表羟基;Z代表卤素原子,取代的烷基磺酰氧基或取代的苯基磺酰氧基,或Y和Z结合代表--O--;A代表取代的1,3-丁二烯基或取代的1,3-氮杂丁二烯基;以及一种含有该化合物作为活性成分的除草剂组合物。式子(I)的化合物对禾本科杂草、莎草科杂草等表现出高除草活性,但对作物的植物毒性明显降低。
