Data Coverage 3 of 6 dimensions
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.

Management
Cultural Controls
- 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.
- Infected pollen should not be introduced into healthy orchards during pollination.
- Establish new plantings in blocks, the larger the better, and preferably at some distance from older orchards.
- Rogue infected trees in new virus-indexed orchards, but it is not economical to rogue or replant mature infected orchards unless trees are infected with the rugose strain.
- Complete orchard removal should be considered.
