Fruit falls off the plant before ripening

Black Currant Run-Off

• Causal organism: Botrytis cinerea Pers.
• Crops affected: Black, red, and white currants

Premature fruit drop can be a problem in currants, particularly black currant, production. Some cultivars are more genetically pre-disposed to this condition which is linked to infection by the fungus Botrytis cinerea.
