Botrytis Blight

A fungal disease which attacks cankered stems and flowers. The fungus grows into a gray brown fuzz mycelium that causes the flower petals to turn brown and shrivel. The predisposing factors are cooler and moist weather conditions. This can be accelerated by weakened plant tissues. Stressed plants are highly susceptible to the disease pathogens.


Infection usually begins spotted flower petals.
A grayish brown fuzz grows on infected plant parts.
Flowers shrivel and decay.
