- Observation Little cherry infected 69% of older trees.
- Observation Necrotic ringspot/prune dwarf infected 56% of older trees.
- Observation European rusty mottle infected 35% of older trees.
- Observation Ring mottle infected 30% of older trees.
- Observation Necrotic rusty mottle infected 3% of older trees.
- Observation Most newer varieties were virus free.
- Observation Newer varieties contracted all listed viruses except necrotic rusty mottle.
- Association Several virus infections diminished yield in three varieties.
- Mechanism Rusty mottle reduced growth and tree size.
- Mechanism Other viruses also impaired fertility.
- Association Virus infection enhanced yield of Merton Heart.
- Association Virus infection probably reduced potential yield by at least 30%.
