Pink or reddish fibers may be the telltale sign of red thread, a foliar turf grass disease that is usually seen in the cooler moist weather of spring and fall when your lawn is still growing slowly. Red thread disease most commonly occurs because of low fertility, drought, lack of sunlight, or other causes of stress.
While affected areas of grass appear to be dead, red thread doesn't kill the grass. The fungus that infects the turf lives in the thatch and is spread by water, wind, equipment and people. The pink growths that appear in the grass do not infect the crown or the roots of the plant, so although unsightly, the grass is not killed by the fungus.
Proper cultural practices to discourage red thread include:
Often times, an application of fertilizer will reduce the severity of red thread. Treating red thread with a fungicide is generally not necessary for home lawns but fungicides are a viable option for extreme cases or for those who find it aesthetically unpleasing.
