Non-Chemical Management
- Provide proper planting sites and culture. Healthy trees are more resistant to disease and winter injury.
- Avoid wounding trees.
- Avoid overhead watering.
- 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.
- Rake and destroy infected twig debris.
- Correct pruning practices minimize injury and improve wound healing. For information see PNW 400, Training and Pruning Your Home Orchard, or contact WSU Master Gardeners or your county Extension agent.
