Recommended Controls
Wilt of Multiple Crops - Fusarium
Fungus
Non-Pesticide
Use disease-free seed and transplants. Avoid fields with a
history of the disease. Rotate to non-Solanaceous, nonCucurbit
crops for >6 years. Use raised beds and mulch to
improve drainage and reduce splashing. Prompt destruction
of the finished crop with tillage to rapidly breakdown tissue is
an important method to prevent disease build-up.
