Red Thread

This entry was posted in Diseases on by .

Red Thread is a foliar disease that does not affect the crown and roots of your lawn, simply put it is merely cosmetic.

Symptoms of Red Thread appear as circular, pinkish red to tan patches, 2-4 inches in diameter. The pathogen produces a red or pink like structure which can be seen with the naked eye on infected leaves. A mix of healthy and diseased grass blades gives the turf a ragged appearance.

Red Thread is favored by overwatering, high humidity, and wide range of temperatures, but the optimum range is 60-75°F.

In order to manage Red Thread water less frequently with longer deep root watering sessions.  If possible, avoid watering at night and on humid days.  The turf will eventually recover, and the disease will grow out on its own.
