Description
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.
Cultural Solutions
Currently there is no known cure for Rose Rosette. If a rose is exhibiting symptoms, the recommended method is to remove and destroy the plant immediately. Other roses can contract it from the infected plant. For more information, visit the American Rose Society.
