The invention relates to novel substituted benzoylpyrazoles of the general formula (I), in which Z is a possibly substituted 4 to 12-membered, saturated or unsaturated, monocyclic or bicyclic heterocyclic grouping which contains between 1 and 4 heteroatoms (up to 4 nitrogen atoms and possibly, either in addition or alternatively, an oxygen atom or a sulphur atom or an SO grouping or an SO2 grouping) and in addition contains between one and three oxo-groups (C=O) and/or thioxo-groups (C=S) as components of the heterocyclic compound. The invention also relates to a method of producing said benzoylpyrazoles and to their use as herbicides.
