How to Manage Pests

Pests in Gardens and Landscapes

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.
