Abstract

Substituted 4-benzoylpyrazole of the formula I ##STR1## where: PA1 Q is a pyrazole of the formula II ##STR2## PA1 X.sup.1 is a straight-chain or branched C.sub.1 -C.sub.6 -alkylene, a C.sub.2 -C.sub.6 -alkenylene or a C.sub.2 -C.sub.6 -alkynylene chain which is interrupted by a hetero atom selected from the group consisting of: PA2 oxygen and sulfur, PA1 Het is a three- to six-membered partially or fully saturated heterocyclic group or a three- to six-membered heteroaromatic group having up to three hetero atoms selected from the following three groups: PA2 nitrogen, PA2 oxygen in combination with at least one nitrogen or PA2 sulfur in combination with at least one nitrogen; and agriculturally useful salts thereof, processes and intermediates for preparing compounds of the formula I, compositions comprising them and the use of the compounds of the formula I and of compositions comprising them for controlling harmful plants are described.
