Abstract

Saccharin derivatives of the formula I ##STR1## where the substituents have the following meanings: L and M are hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio, chlorine, cyano, methylsulfonyl, nitro or trifluoromethyl; PA1 Z is hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.3 -C.sub.8 -cycloalkyl, C.sub.3 -C.sub.6 -alkenyl, C.sub.3 -C.sub.5 -alkynyl, C.sub.1 -C.sub.4 -acyl, benzyl or phenyl, the phenyl rings in each case being unsubstituted or substituted by halogen or C.sub.1 -C.sub.4 -alkyl; PA1 Q is a radical T-J, where PA2 T is a carbonyl radical CO or the radical --CHY, PA2 J is a 4-linked isoxazole ring of the formula II ##STR2## where R.sup.1 is hydrogen or C.sub.1 -C.sub.4 -alkyl and PA1 R.sup.2 is C.sub.1 -C.sub.4 -alkyl, cyclopropyl, 1-methylcyclopropyl or 1-methylthiocyclopropyl; PA1 Y is an OH group, a hydroxyl group which may be acylated by C.sub.2 -C.sub.4 -acyl or a chlorine atom; and agriculturally customary salts of the compounds I are described.
