Phomopsis canker

Phomopsis spp.

Recommendations include removing and burning all blighted or discolored wood during dormant pruning. When blighted tips appear in the summer, cut shoots back to a point where the pith appears normal. Avoid planting sites prone to spring frosts and use fertilization, irrigation, and weed control practices that discourage late-season growth and promote early hardening off. Sprays for mummy berry and botrytis may help, particularly during flowering. However, remember that fungicides active against mummy berry may not be active against phomopsis canker and vice versa.
