Cherry : Witches'-broom (Cherry leaf curl)
(revision date: 5/20/2014)
Use Integrated Pest Management (IPM) for successful plant problem management.
Biology
Witches'-broom disease of cherry is a fungal disease similar to peach leaf curl. Infected branches develop large, dense, broomlike tufts of foliage. These branches typically do not produce flowers or fruit, making them particularly conspicuous during bloom. The leaves are discolored (red to brown), thickened, and curled or puckered. Whitish fungal growth may be present on the underside of curled leaves. Diseased leaves occur both in witches'-brooms and on normal branches. Diseased branches do not recover.
Management Options
Non-Chemical Management
Cut out witches'-brooms at least 12" below lowest infected point.
Select non-chemical management options as your first choice!
