Premature Fruit Drop
Damage: Flowers and leaves have red streaking during bloom. Berries begin to develop, reach 3-5 mm in size and then prematurely turn blue and drop. Infected bushes stand taller than neighbouring bushes as they have no fruit. Symptoms have only been noted on Bluecrop.
Disease: The causal agent of this disease is not well understood.
