White Grass blades = Powdery Mildew
Lots of calls this week about white grass blades. This fungus occurs on Kentucky Bluegrass in our area during cool weather, especially in shaded areas. Tall fescue is resistant. It won’t kill the bluegrass, but will damage the blades. It will disappear when weather warms and grow out of it. Fungicide is not necessary or recommended to treat powdery mildew, especially on home lawns.
