Grey mould (Botrytis cinerea) of tomato

Grey mould of protected tomato is a widespread, common and potentially devastating disease. It can affect all parts of the growing crop and is also a cause of postharvest fruit rot. With increasing adoption of measures that reduce heat use during crop production, there is a greater risk of damaging attacks by Botrytis.
