Which of the following is a common turf disease caused by fungi?

Dollar spot is a common turf disease caused by fungi, specifically the fungal pathogen Sclerotinia homoeocarpa. This disease is characterized by circular, tan-colored patches on the turf that can be quite damaging if not managed properly. The fungus thrives in warm, humid conditions and affects many types of grasses, often leading to significant aesthetic and economic impacts on lawns and turf areas.

In addition to its visible symptoms, dollar spot is known for being particularly aggressive under certain conditions, such as when the turf is excessively nitrogen-deficient or stressed from drought. Effective management practices include proper irrigation, mowing, and fertilization, alongside fungicide applications when necessary.

Understanding this disease is crucial for turf management professionals, as recognizing the symptoms early allows for timely intervention, which is essential in preserving the health and appearance of the turf.
