Dollar spot is recognizable by the appearance of what?

• A. Long black streaks on blades
• B. Small bleached spots the size of a quarter
• C. Pink fungal strands
• D. Purple lesions

Answer: (B)

Dollar spot shows up as small, bleached, tan to straw-colored spots on the leaf blades, typically about the diameter of a coin like a quarter. These tiny circular lesions reflect loss of chlorophyll and appear as pale patches on healthy turf. Under conditions of persistent leaf wetness and high humidity, these spots can enlarge and merge into larger areas. This distinctive coin-sized, pale spot pattern is what you look for to identify dollar spot, rather than long streaks, pink filaments, or purple lesions which are characteristic of other diseases.
