Use IPM (Integrated Pest Management) for successful plant problem management.

Biology
Prunus necrotic ringspot is a viral disease affecting most cultivated Prunus species. Leaves may show various symptoms including brown, sunken, necrotic spots; chlorotic (yellowish to white) blotches or other patterns; or dark rings etched on the leaf. The necrotic spots may drop from the leaf, giving it a "shotholed" appearance. The disease is spread to healthy trees via infected pollen and by grafting.

Management Options

Plant and graft only with stock that is certified virus-free.
Remove infected trees from orchards, if desired.
