Adequate rainfall coupled with warm days and cooler nights this spring has lead to increased dollar spot activity on both cool and warm-season turfgrasses.  Dollar spot activity will continue until daytime highs consistently exceed 90°F.  Turfgrasses that are deficient in nutrients, especially nitrogen, are more susceptible to dollar spot and will take longer to recover than well-fertilized turf.
