Abstract

Anilinopyrimidine-resistant phenotypes of Botrytis cinerea are recorded for the first time in Australian vineyards. The frequency of resistance among the 910 isolates obtained during 1997/98, 1999/2000 and 2000/01 was 0%, 12% and 4%, respectively. There were two resistant phenotypes and these were designated as low resistant (EC50 = 1.5 mg/L) and resistant (EC50 = 2.5 mg/L). Both the resistant phenotypes were found to possess multiple resistances to benomyl (benzimidazole) and iprodione (dicarboximide). It is considered that the frequency of anilinopyrimidine resistance observed currently in Australian vineyards does not pose any immediate risk in the use of pyrimethanil for management of Botrytis bunch rot.
