Red thread is a turfgrass disease caused by the fungal pathogen Corticium fuciforme. This disease typically starts at the tips of the grass blades and then progresses downward, giving it a distinctive appearance. The characteristic red, fiber-like material that protrudes from the ends of the cut leaves is a key identifying feature of this disease.

Infected grass often shows signs of deterioration, with thinning turf and reddish strands that can create a somewhat unappealing visual effect. Red thread is commonly observed in cooler weather, particularly during periods of high humidity, which promotes the growth of this pathogen.

Understanding the signs and symptoms of red thread is important for effective lawn management and treatment, making it crucial for individuals preparing for pesticide certification to be aware of its identification and appropriate management practices.
