Data Coverage 3 of 6 dimensions
You'll see green and yellow mottled leaves with green coloring along veins on sour cherry rootstocks (Prunus cerasifera), followed by premature leaf drop and reduced fruiting spurs. Prune dwarf virus spreads through budding, grafting, and infected pollen. Use virus-tested nursery stock and establish new plantings away from old orchards. Roguing mature orchards is uneconomical; thermotherapy can eliminate the virus in propagation material.
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 budwood 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 budwood and virus-certified rootstock.
- Do not introduce infected pollen 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.
- Thermotherapy (24 to 32 days at 38°C) and/or apical meristem culture have been used to eliminate various viruses.
