Cucurbit Downy Mildew
A foliar, fungal like disease of cucumbers, cantaloupe, melons, squash and pumpkins, Pseudoperonospora cubensis generally arrives in North Carolina in May or June and escalates through fall.
Minimize cucurbit downy mildew damage by:
- Keeping leaves dry when possible:
- Water the soil rather than the plant
- Use drip irrigation
- Water early in the day
- Space plants to allow air circulation.
- Plant early in the season to harvest before fall when disease levels are highest in North Carolina.
At present, no resistant varieties are available.
