Non-Chemical Management
- Remove infected plants, including roots larger than 1" in diameter.
- Air-dry soil from infected site before replanting.
- Provide proper culture to decrease stress and encourage vigorous, disease-resistant trees.
- Plant only resistant plant species in infected areas (when possible). A list may be found in the PNW Plant Disease Management Handbook or contact your county Extension agent or WSU Master Gardeners.
