Blueberry: Mummy berry

Mummy Berry Shoot Blight

Mummy berry fungus can infect leaves. Following infection, leaves become necrotic and are covered with powdery masses of gray spores during wet weather.

These primary shoot blight infections occur when spores are rain splashed and wind carried from mushrooms cups developing from mummfied fruit on the ground under bushes.

Mummy Berry Fruit Infection

Mummy berry infected fruits shrivel and turn pink. They are inedible. Mummified fruit drop to the ground prematurely. These overwinter to cause primary leaf infections the following spring.
