Fenchlorazole-ethyl, Cloquintocet-mexyl

In the above-mentioned combination, fenoxaprop-ethyl/fenchlorazole-ethyl the racemic form of the herbicide was subsequently replaced by the biologically active 

As already mentioned, it is a major advantage of mefenpyr-diethyl to act as a safener also in combination with sulfonylurea herbicides in cereal species. Combinations have been developed with the sulfonylureas iodosulfuron-methyl-sodium and mesosulfuron-methyl. 

Studies on the mode of safener action in wheat indicated that the safener enhanced the metabolic degradation of both herbicides in the crop species, while it did not significantly alter their rate of degradation in the target weed species wild oats and blackgrass Alopecurus myosuroides) [14, 21, 49].
