Prunus Necrotic Ringspot

Prunus necrotic ringspot causes ring-shaped lesions on fruit and leaves of stone fruit. This viral condition spreads through pollen and seed. Remove infected trees and replant with virus-tested stock. Control aphids and other vectors. Proper sanitation and resistant varieties offer the best management approach. Rot diseases are difficult to manage once established. Focus on prevention through proper culture and site selection.

Use nursery stock that has been tested and found to be free of all known viruses. If propagating your own trees, use both virus-indexed bud wood and virus-certified rootstock.
