Non-Chemical Management
- Crop rotation may be useful, but do not plant potato or tomato (except resistant varieties) into infested soil.
- Plant healthy seedlings.
- Plant resistant varieties (typically indicated by "V" in seed catalogs). A list is available in the current PNW Plant Disease Management Handbook. Other Verticillium-resistant vegetables include celery, lettuce, peas, beans, and asparagus.
- Control weed hosts (including nightshades) in and around the garden.
- Clean up plant debris and destroy or discard (do not compost) diseased materials.
