How large are the spots created by dollar spot on the grass?

Dollar spot is a common turfgrass disease, particularly in warm-season grasses, and is characterized by small, circular spots of dead grass. The size of these spots is typically around 2 to 3 inches in diameter. This size is significant because it informs both diagnosis and treatment strategies for managing the disease. Understanding that the spots are within this diameter range enables turf managers to accurately identify dollar spot among other grass diseases, which can sometimes present similarly.

Other sizes mentioned do not align with the characteristics of dollar spot. For instance, spots less than 2 inches would typically indicate a different issue, while those exceeding 3 inches would likely be indicative of other diseases or issues that affect turfgrass. Thus, recognizing the specific size helps in determining the correct management approach for this particular turfgrass problem.
