Powdery mold. In Mideastern lawns, this is one of the most troubling and persistent turf ailments that starts in spring and runs through the summer. To begin with, we thought it would be good for you to have a mental image of what this disease looks like.
This destructive and dusty disease appears as grayish or white growth on upper surfaces of grass leaves. While all grasses are susceptible to powdery mildew, it is most apparent on Kentucky bluegrass and tall fescue.
When is Your Turf Primed for Attack from Powdery Mildew?
Powdery mildew is most likely to happen in lawn areas with low sunlight, high humidity, low air movement, and warm temperatures. Lawns that are shaded are predisposed to powdery mildew.
What can you do to Rid your Turf of this Disease?
Powdery mildew loves and will actively seek the shade, so pruning to eliminate shade may help. Using a grass that tolerates the shade such as many variances of bluegrass or fine fescue can stop its appearance outright. In very thin areas, a good fungicide can help but it is really not worth the expense or trouble as if you just read and follow the instructions on this posting from us here at Briggs and Stratton Repair, you will be free from powdery mildew all year long!
