In all vineyards in the Pfalz area (FRG) where the dicarboximide fungicides have been applied, resistant isolates can nowadays be found. These do not differ from the sensitive ones in uptake of the active ingredient of the dicarboximides or in the number of nuclei in spores or hyphal cells. The percentage of resistant strains decreases in the population when there is a long gap between applications of the fungicides. As a possible explanation, we have observed tendencies to resensitization in all resistant isolates. The degree of resensitization varies according to isolate.
