Abstract

Herbicidally active phenyldiketone compounds of the formula I ##STR1## in which the substituents have the following meanings: L and M are hydrogen, C.sub.1 -C.sub.6 -alkyl, C.sub.2 -C.sub.6 -alkenyl, C.sub.2 -C.sub.6 -alkynyl, C.sub.1 -C.sub.4 -alkoxy, it being possible for these groups to be unsubstituted or substituted by one to five halogen atoms or C.sub.1 -C.sub.4 -alkoxy, or halogen, cyano, nitro, a group --(Y).sub.n --S(O).sub.m R.sup.7 or a group --(Y).sub.n --CO--R.sup.8, PA1 Z is a 5- or 6-membered heterocyclic saturated or unsaturated radical which has one to three hetero atoms selected from the group consisting of oxygen, sulfur or nitrogen and which is unsubstituted or substituted by halogen, cyano, nitro, a group --CO--R.sup.8, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.3 -C.sub.8 -cycloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, C.sub.1 -C.sub.4 -alkylthio, C.sub.1 -C.sub.4 -haloalkylthio, di-C.sub.1 -C.sub.4 -alkylamino or which forms a bicyclic system with a substituted or unsubstituted phenyl ring, a fused carbocycle or a fused second heterocycle, PA1 Y is O or NR.sup.9, PA1 n is zero or one, PA1 m is zero, one or two, PA1 R.sup…
