Powdery mildew is a fungal disease that appears as a dusty gray or white coating on plants. Vegetables such as cucumber, pumpkins, squash and melons; houseplants such as African violet and begonia; and outdoor plants such as phlox, lilac and rose are all susceptible to powdery mildew. Not only is the disease unattractive, but it can distort and stunt a plant’s leaves, buds, tips and fruit. If enough leaves or tissue are affected, the plant may die.

How Powdery Mildew Forms
-
Wind carries powdery mildew spores. The disease can appear at any time, but it’s more likely to grow rapidly in shady areas, if there is slow or nonexistent air circulation or when the humidity is high. Powdery mildew can reproduce both sexually and asexually.
Prevention
-
If you’re planting a susceptible specimen, choose an area with as much sun as the plant can handle. Don’t crowd the plant; make sure there is enough room for air to circulate. Use a slow-release fertilizer; avoid liquid fertilizers that may splash spores back onto the leaves. Water the plants at the root level, not from above. Plant varieties resistant to powdery mildew.
