Tolerance to benomyl in Botrytis cinerea and Fusarium oxysporum

In 1974, a field survey revealed a widespread occurrence of benomyl tolerance in Botrytis cinerea. When young mycelium discs were transferred to media with different benomyl concentrations, various tolerance groups could be distinguished, Cultures obtained by hyphal tip isolations from these isolates and replicated by means of a multipin replicator showed only two types of response: inhibition by 0
