While Botrytis cinerea is capable of colonizing damaged artichoke leaves, the main concern with this fungus is on the flower bracts.
Infected bracts turn brown on the outside.
The fungus survives on decaying organic matter in and around artichoke fields. Senescent leaves may also support the growth of this fungus. Botrytis rot is typically more severe following periods of wet, rainy weather. This disease is also a postharvest concern because damaged or improperly handled artichoke buds can develop symptoms in storage. Handle harvested buds properly.
