Biology and management of Botrytis blight


Botrytis cinerea is an important pathogen of conifer seedlings in western North America, especially within greenhouses. Environmental conditions in greenhouses, such as high humidity and cool temperatures, are conducive to infection by and spread of this fungus. To reduce losses from Botrytis blight, cultural practices aimed at reducing inoculum and altering environmental conditions necessary for infection should be combined with rotated use of different fungicides. Several fungicides used to control Botrytis in the past are no longer effective because the fungus has developed tolerance to them. Fungicides commonly used to control this disease are discussed.
