Powdery Mildew

Powdery mildew forms a white coating on leaf surfaces during dry, cloudy weather with high humidity. It is caused by any one of several fungi. Plants growing in shaded areas are often the most affected.

 

Damage
Leaves are covered with a thin layer or irregular patches of a powdery, grayish-white material. Leaves may become distorted. Infected leaves may turn yellow or red and drop. In late fall tiny black dots are scattered over the white patches like grains of pepper.

Control
When planting new trees and shrubs, choose resistant varieties. Some groups of highly susceptible plants, such as crape myrtles, crabapples, and lilacs, have cultivars selected for resistance to powdery mildew. Several fungicides are available that will control this mildew.
