  • Infected plants should be removed and destroyed.
  • Sanitize pruning and other tools between plants or blocks of plants.
  • Use two tools so a worker can trim or cut with one while the other soaks.
  • When done with a batch, cultivar, etc. switch one tool for the other and allow the used one to soak.
  • Sanitation should also be practiced when taking cuttings for propagation.
