Dollar spot can occur on all turfgrass species.

• A. True
• B. False
• C. Only on warm-season grasses
• D. Only on cool-season grasses

Answer: (A)

Dollar spot is a disease with a broad host range, meaning it can affect many different turfgrass species, not just one family or type. The fungi behind it can infect both cool-season grasses like annual bluegrass, creeping bentgrass, and fescues, as well as warm-season grasses such as bermudagrass and zoysiagrass, when conditions are right (leaf wetness, warm temperatures, and not-too-rapid nitrogen supply). The typical symptoms—small circular yellow-brown spots on leaves that may merge into larger patches—can appear across these species, especially on greens and turf with high moisture. Because it can occur on so many turf types, the statement is true. Effective management across species centers on reducing leaf wetness, proper fertility, and timely fungicide applications as needed.
