Non-Chemical Management
- Plant only healthy, disease-free seedlings.
- Do not plant potatoes and tomatoes in close proximity.
- Remove infected plants or plant parts when symptoms are noticed to reduce spread of disease.
- Diseased plant materials should be destroyed or buried deeply (two feet or more).
- Remove plant debris from the garden in the fall. Do not compost diseased materials.
- Space plantings to provide good air circulation.
- Avoid overhead watering.
- Do not dig tubers from infected vines until at least two weeks after vines are completely dead (no green stems remaining). Avoid injuring tubers.
