Prune dwarf virus causes abnormal leaf characteristics in sweet cherry, with leaves narrower and longer than normal. Infected trees show reduced vigor and productivity. Remove infected trees and replant with virus-tested stock. Control aphid vectors to prevent spread. This virus is best managed through prevention. Monitor your plants closely and implement integrated management strategies. Prompt removal of infected material helps limit disease spread.
Use virus-tested (and found to be free of all known viruses) bud wood and nursery stock. Establish new plantings some distance from older orchards.
