Downy Mildew
(Cucurbits)
 Description: A period of at least 6 hours at 100% humidity
on the leaf surface is required for infection. Downy
mildew symptoms vary considerably, plant to plant. Lesions
appear first on the oldest leaves and then spread to
the younger leaves.
Solution: Use plant
spacings which reduce canopy density, and avoid overhead
watering to help reduce the length of time of leaf wetness.
Spray Soap-Shield® Fungicidal Soap
as a protectant.
