Dollar spot is caused by Sclerotinia homoeocarpa. True or False?

• A. True
• B. False
• C. Only in Europe
• D. Not present in Kansas

Answer: (A)

Dollar spot on turf is caused by a fungal pathogen called Sclerotinia homoeocarpa. This organism is the classic culprit behind the disease that forms tiny circular, tan spots on cool‑season grasses, often with a yellowish halo, especially under warm temperatures with leaf wetness. The fungus survives in thatch and soil and produces new infections as conditions stay humid and wet. In newer classifications you may see it named Clarireedia homoeocarpa, but many texts still use Sclerotinia homoeocarpa. So the statement is true, and dollar spot occurs in many places, not just Europe—it's present in Kansas as well.
