Powdery Mildew |
Gray or white circular patches appear on leaves; then whole leaves become powdery white and distorted. Infected leaves may drop, and the entire plant may be weakened or killed. The flavor of peas, squash, and melons may be affected.
While most fungi thrive in moist surroundings, the organisms causing powdery mildew flourish in dry conditions; they also prefer warm days, cool nights, and shade. To control, be sure to provide good air circulation. Spray with fungicide when symptoms first appear. Prune off and destroy infected tissue. |
