SUMMARY An isolate of Botrytis cinerea Pers. ex Fr. insensitive to vinclozolin, procymidone and iprodione was obtained from strawberries which had been inoculated with a benomyl‐insensitive isolate of the pathogen and sprayed with iprodione. This isolate maintained its insensitivity to benomyl and also showed resistance to quintozene and dicloran. Tests on detached strawberry fruits showed that the iprodione‐insensitive isolate was as virulent as a sensitive isolate. No difference was found in the amounts of the fungicides taken up by the insensitive and sensitive isolates of the fungus.
