, : Chemical control of grey mould of grapevine in La Rioja (Spain). EPPO Bulletin 12(2): 81-85

Av. effectiveness of most of the fungicides used against Botrytis cinerea does not exceed 60%. Resistant strs. have possibly appeared recently. Generally plants are treated once at the start of ripening and once 3 wk before harvest.
