Downy Mildew


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.
