Botrytis rot

Botrytis rot, also called grey mould rot, starts with a brown discolouration around lenticels, wounds or the blossom-end of the apple. It is a soft rot (mostly). White-grey mycelium can cover the decayed area that is light brown to brown. The decayed tissue cannot be separated from healthy tissue. The fungus can form large nests of rot in stored fruit. Prevention of infection begins in the orchard. Proper harvesting and handling should limit infections that occur via wounds.
