In addition, the invention relates to processes for preparing compounds of the formula I, to compositions comprising them and to the use of these derivatives or of the compositions comprising them for controlling harmful plants.
Pyrazol-4-ylbenzoyl derivatives are disclosed in the literature, for example in EP-A 282 944, WO 96/26206 and the earlier German patent application DE-A 19 701 446. However, the herbicidal properties of the prior art compounds and their crop plant safety are not entirely satisfactory.
