Red thread is a foliage disease caused by the fungus laetisaria fuciformis. Its symptoms create an undesirable appearance but crowns and roots are not effective so turfgrass usually recovers. Red thread gets its name from the thread-like structures on the tips of infected leaf blades. The red /pink threads or sclerotia are visible without magnification and are useful for identifying the disease in the field. Red thread symptoms appear as circular patches of tan or pink turf about 4-8 inches in diameter and can join into larger areas.


The pink color is caused by the sclerotia, which are the antler-like red threads protruding from the top of the grass blade. Pink mycelium may also be seen on the leaf blade. Other diseases, including dollar spot, pink snow mold, and especially pink patch, have field patterns and symptoms that resemble red thread and are active during similar environmental conditions; however, after close inspection red thread is easily distinguished from other diseases by the presence of the sclerotia.


Red thread most commonly affects Kentucky bluegrass, perennial ryegrass, and tall fescue, which is also the most common seed blend for the Midwest. Outbreaks

usually occur in low maintenance turf stands such as residential lawns and golf course roughs. Red thread development is most common with slow growing turf with poor fertility. Disease development occurs over a relatively wide range of cool conditions 40-70° F, typically in the spring and fall, especially during long evening dew periods.



Maintaining a healthy and vigorous turf is the most effective method of Red thread control. Core aeration should be done annually, avoid late day watering, water

infrequently and deep, and maintain turf fertility will lessen your susceptibility for Red thread development. A good lawn maintenance program implemented over two to three years should drastically reduce further red thread problems.



Fungicides are not usually advised for red thread control on residential turf for various reasons. The disease is largely cosmetic. Unless environmental conditions that promote disease development persist for extended periods the turf will recover with no lasting effects of infection. There are situations when fungicides for red thread control on residential turf are warranted. In those cases, effective fungicides should be applied by licensed applicators when the pathogen is active.
