Cherry : Prunus necrotic ringspot
(revision date: 5/20/2014)


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


Non-Chemical Management
  • Remove infected trees from orchards, if desired.
  • Plant and graft only with stock that is certified virus-free.
Select non-chemical management options as your first choice!
