    Botrytis Cinerea an overview ScienceDirect Topics. BIOLOGY AND MANAGEMENT OF BOTRYTIS BLIGHT Robert L. James ABSTRACT 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, The most recent work has been done on the grapevine/ Botrytis cinerea system where the pathogen’s life cycle was disturbed and levels of primary inoculum were reduced through the use of organic mulches or of cover crops, mulched in situ. Levels of primary inoculum from vine debris were reduced under mulch, through an increase in the activity.

    Botrytis cinerea 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". Gray mold is caused by the fungus Botrytis cinerea. The fungus is capable of infecting a great number of different plants. The disease cycle is very similar for both strawberries and brambles. The fungus overwinters as minute, black, fungus bodies (sclerotia) or as mycelium in plant debris, such as dead strawberry or raspberry leaves.
