Powdery Mildew

How to Identify Powdery Mildew

Powdery mildew first appears on the leaves as individual tufts of fine, white mycelium. The tufts enlarge and coalesce, causing the leaves to have a grayish-white or powdery appearance. Severely infected turf turns yellow, then tan and brown in color.

Why Is Powdery Mildew a Problem for Your Lawn?

This lawn disease is typically a result of grass that is already under stress, high humidity, has poor circulation and shady areas in the mid-60’s. Turf that is severely infected, especially in shaded areas, can become thinned and/or die.
