What is a common visual symptom of dollar spot in turfgrass?

Dollar spot is a common turfgrass disease caused by the fungal pathogen Sclerotinia homeocarpa. One of the hallmark visual symptoms of dollar spot is the appearance of small, circular spots that often measure from about 2 to 6 inches in diameter. These spots typically have a lighter tan or straw color in the center, resembling dollar coins, which is how the disease received its name.

This symptom is especially characteristic of the disease and helps in its identification among other turfgrass issues. The small, circular nature of the spots is significant in distinguishing dollar spot from other turf diseases, which may present differently.

The other potential symptoms listed, such as dark green patches or long brown stripes, do not accurately represent dollar spot's typical visual characteristics and are more associated with other turf-related issues. Wilting leaves may suggest other stresses, such as drought or disease, but do not specifically relate to the visual symptoms of dollar spot infection.
