Tree Diseases: Powdery Mildew

Powdery Mildew is a relatively easy disease to spot when it infects trees and shrubs in the landscape. Although the disease will not kill the plant outright, it will compromise the health of the plant and leave it more susceptible to other diseases, insects or stresses.

The first signs of powdery mildew are light green or yellow spots on the leaf of the plant. As the disease matures, a white film covers portions or the entire leaf (the appearance of flour sprinkled over the leaf). The disease tends to target plants in spring and fall when weather is cool and humid, though it may show up anytime during the growing season if ideal conditions are met.
