Non-Chemical Management
- Rotate crops. Do not plant crops in the same location each year. Do not plant susceptible crops where previous infections occurred.
- Space plantings to provide good air circulation.
- Avoid overhead watering. Water early in the day, to allow plants to dry before night.
- Provide proper culture. Avoid overfertilization, which produces large amounts of tender, susceptible growth.
- Remove and destroy infected plants when noticed.
- Remove plant debris from the garden. Destroy or discard (do not compost) diseased materials.
- Do not move infected soil to uninfested areas.
