  • the combination of the active ingredient of formula I under a) with one or more.active ingredients selected from the co-herbicides under b) exceeds the additive action on the weeds to be controlled that is to be expected in principle and thus broadens the range of action of the individual active ingredients especially in two respects: firstly, the rates of application of the individual compounds of formula I under a) and co- herbicides under b) are reduced while a good level of action is maintained. Secondly, the composition according to the invention achieves a high level of weed control also in those cases where the individual substances, in the range of low rates of application, have become useless from the agronomic standpoint.
