Fungicides are effective if cultural controls fail. These grow together and cover much of the leaf surface, generally the lower ones. Leaves may become puckered and eventually yellow. It is usually observed in spring and fall during cool humid periods and most often found in shaded areas where air circulation is poor. Heavy fertilization favors this disease.
Control strategy includes a blend of shade-tolerant grasses.
Pruning woody plants to reduce shade intensity and allow better air movement also aids in control. Mowing higher during disease periods and reducing fertilizer applications will reduce infection. Plants appear water soaked and die rapidly. When air is moist, colorful red disease strands are produced at the leaf tips, giving the turf a reddish appearance. Maintain a balanced fertilizer program and water to prevent stress.
