First report of grey mould caused by Botrytis cinerea on Hibiscus acetosella

Botrytis cinerea is reported for the first time causing grey mould of cranberry hibiscus, Hibiscus acetosella, in Brazil and worldwide. The fungus was characterised morphologically and an ITS sequence helped confirm its identity. The fungus was isolated in pure culture and its pathogenicity to H. acetosella was demonstrated.
