Powdery mildew
If a whitish-gray, cotton-like, powdery, moldy coating appears on the blades of grass, it is a fungal disease of the lawn. In advanced cases, small black spots may form in the center of the coating.
The disease occurs most frequently in the spring and summer during warm, humid weather. Without treatment, the affected leaves will die off completely.
