Cane blight—Leptosphaeria
coniothyrium
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.
Solutions
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
plants. A dormant application of lime
sulfur at the cane base
may help reduce disease incidence. |
