Red Thread Lawn DiseaseRed Thread Lawn Disease

on April 19, 2013 by TruGreen

Does your lawn have small, bleached, light pink or red patches? If so, your lawn may have red thread lawn disease. Don’t panic. These things happen. I’m here to talk you through it … and don’t feel bad. Grass diseases can happen in any lawn.

Red thread lawn disease (aka Pink Patch) is a grass fungus disease that is more severe in the cooler, more humid areas of the Pacific Northwest on damp, slow-growing, nitrogen-deficient turfgrass such as bluegrasses, bentgrass, fescues, bermudagrass and perennial ryegrass.

Small, water-soaked spots cover a large portion of the grass leaf, and as they enlarge, the tissue dries out and fades to a tan color. The leaf may also be covered with pink fungal growth that extends from the ends of the leaf blade and onto the surface of the leaves. If you search online for red thread lawn disease pictures, you’ll see that these spots can range from 2 inches to 3 feet in diameter and have an uneven, ragged appearance.

One of the biggest contributing factors in the appearance and spread of red thread lawn disease is low soil fertility. Not coincidentally, the best way to treat this particular grass fungus is with a balanced lawn fertilization program and specific watering habits, even though some fungicides do suppress these types of grass diseases. However, in most cases, there’s no real need to use a fungicide—but that’s a decision for an expert to make, depending on the severity of the disease or as a preventative measure.

If you suspect your lawn may have red thread lawn disease or some other grass fungus, bring in the trained eyes of a TruGreen® PhD-certified specialist and let him or her perform a Healthy Lawn Analysis® on your yard. TruGreen will design a tailored approach to give your lawn exactly what it needs at exactly the right time. Call them now at 866.688.6722 or visit to learn more.
