Abstract
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.
