Non-Chemical Management
- Provide proper planting sites and culture. Healthy trees are more resistant to disease and winter injury.
- Avoid wounding trees.
- Control insect and disease problems to minimize injuries.
- Prune out and destroy infected tissues during dry weather. Make cuts at least 12" below visibly infected area. Sterilize pruning tools frequently.
- Rake and destroy infected twig debris.
- Correct pruning practices minimize injury and improve wound healing. For more information see PNW 400, Training and Pruning Your Home Orchard, or contact your WSU Master Gardeners or county Extension agent.
