Abstract

The present application relates to saccharin-5-carbonyl derivatives of the formula I in which the substituents have the following meanings:L is C1-C6-alkyl, C1-C6-alkoxy;Z is C1-C6-alkyl, C3-C8-cycloalkyl, C3-C6-alkenyl, C3-C5-alkynyl, phenyl-C1-C6-alkyl or phenyl, where the phenyl rings are in each case optionally mono- or polysubstituted by C1-C6-alkyl, C1-C6-alkoxy or halogen;M is hydrogen, C1-C6-alkyl, C1-C6-alkoxy, halogen, cyano, nitro or halo-C1-C6-alkyl;R1, R2, R3, R4, R5, R6, R7, R8 are hydrogen, C1-C6-alkyl;and agriculturally utilizable salts of the compound I.
