Botrytis cinerea ("botrytis" from Ancient Greek botrys (βότρυς) meaning "grapes" plus the New Latin suffix -itis for disease) is a necrotrophic fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as "botrytis bunch rot"; in horticulture, it is usually called "grey mould" or "gray mold".
