Spur Blight
Didymella applanata

• Leaf and flower buds shrivel and die, and young fruit may fail to develop
• Brown wedge-shaped area on leaves
• Chestnut brown to purple oval lesions on young green canes where the leaves attach
• Brownish purple lesions enlarge into streaks and cover much of the cane
• As diseased canes mature, the outer layer dries out and becomes silvery. Cracked, tiny black dots can be seen on the silvery epidermis.
