Branches infected with cane blight wilt and turn black or brown. Dead leaves and fruit cling to branches.
Infected canes may turn color and encircle the stem.
The cane blight fungus overwinters on canes. Its spores are spread in the wind. Plants can be infected
through pruning wounds, growth cracks, or injured roots. Prune out
infected canes, being careful not to injure plants. Prune
during dry weather. Remove and destroy severely infected
leaves clinging to branches
