• A. Large brown patches with yellow edges
• B. Small bleached white spots of 1-2 inches in diameter
• C. Water-soaked appearances on the leaf edges
• D. Distinctive reddish-brown lesions on the soil

Answer: (B)

The characteristic symptom of Dollar spot in closely mowed turf is the presence of small bleached white spots that typically measure 1-2 inches in diameter. This fungal disease is caused by the pathogen Sclerotinia homeocarpa and often manifests in conditions where grass is closely mowed, with the spots appearing as light-colored, sunken lesions on the leaf blades. These bleached spots may appear during warmer months and are often surrounded by a healthy green area, which contributes to the distinctive appearance of the disease. Recognizing these small white spots is crucial for effective diagnosis and management of Dollar spot, as early intervention can help mitigate damage and control the spread of this turfgrass disease.
