Abstract

An herbicidally effective benzoyl derivative having the formula: ##STR1## wherein X.sub.1 is C.sub.1 -C.sub.4 alkoxy or halogen; PA0 X.sub.4 is hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy or halogen; PA0 X.sub.5 is hydrogen or fluorine; PA0 Y.sub.1, Y.sub.2, Y.sub.3, Y.sub.4 and Y.sub.5 are independently hydrogen or C.sub.1 -C.sub.4 alkyl; PA0 R.sub.1 is C.sub.1 -C.sub.4 alkyl; PA0 R.sub.4 is C.sub.1 -C.sub.3 alkyl; PA0 n is an integer of 0, 1 or 2 is discosed. In addition, the herbicidally effective benzoyl derivative having the formula: ##STR2## wherein: X.sub.1 is C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy halogen; PA0 X.sub.4 is hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy or halogen; PA0 X.sub.5 is hydrogen or fluorine; PA0 Y.sub.1, Y.sub.2, Y.sub.3, Y.sub.4 and Y.sub.5 are independently hydrogen or C.sub.1 -C.sub.4 alkyl; PA0 R.sub.1 is C.sub.1 -C.sub.4 alkyl; PA0 R.sub.4 is C.sub.1 -C.sub.3 alkyl; PA0 n is an integer of 0, 1 or 2; PA0 L is C.sub.1 -C.sub.4 alkylene is disclosed.
