Abstract

Cycloalkyl-substituted benzoylpyrazoles of the formula I where the variables have, for example, the following meanings:R1 is hydrogen, nitro, halogen, cyano, thiocyanato, or an unsubstituted or substituted aliphatic radical;R2 is an unsubstituted or substituted aliphatic radical, halogen, nitro, or substituted sulfonyl or amino groups,R3 is hydrogen, halogen, C1-C6-alkyl, C1-C6-haloalkyl, C1-C6-alkoxy, C2-C6-alkenyl or C2-C6-alkynyl;R4, R5 are hydrogen, nitro, halogen, cyano, thiocyanato, an unsubstituted or substituted aliphatic radical or substituted sulfonyl or amino groups;R6 is hydrogen, halogen, C1-C6-alkyl, C1-C6-alkoxy, C3-C8-cycloalkyl;R7 is a cyclic ring system having 3-14 ring atoms;R16 is hydroxyl or a substituted hydroxyl group;and their tautomers or agriculturally useful salts are described.Moreover, the invention describes processes for preparing compounds of the formula I, compositions comprising them, and the use of the compounds of the formula I and of the compositions comprising them for controlling harmful plants.
