Non-Chemical Management
- Do not replant susceptible species in infected soil.
- Plant disease-free materials.
- Avoid injuries to the bark, roots, and crown while planting.
- Remove and destroy declining plants with large crown galls. Also remove roots and surrounding soil where possible.
- Prune out galls when practical. Sterilize pruning tools between cuts to avoid spreading bacteria to healthy tissue.
