Red Thread
Red Thread is a fungal disease that affects turfgrass in cooler, more humid conditions, particularly in spring and fall. Red Thread gets its name from the pink to red antler-like structures (sclerotia) that form at the end of the infected grass blades. As the disease progresses, small (4 to 8 inches), circular dead patches with a pinkish or tan cast appear in the lawn. It most commonly affects Kentucky Bluegrass, Perennial Ryegrass, and Tall Fescue.
