Abstract/Contents:"Management of dollar spot (DS; Clarireedia jacksonii) in turfgrass has been increasingly challenging. While cultural practices have shown positive impacts on disease management, there are limited reports on the effectiveness of integrated cultural practices. Field studies were conducted to evaluate the interaction of dew removal, nitrogen fertilization, and plant growth regulator (PGR), as it relates to DS severity and turf quality on golf course greens and fairways. The study was conducted in four locations, including Wisconsin, Ohio, Pennsylvania, and Virginia. A randomized complete block design was used with 2x2x2 factorial arrangements and four replications. The treatments included two dew treatments (dew removed or not), nitrogen fertilization (applied or not), and PGR (Prohexadione-Ca applied or not). While there were some variations in the results, N and dew removal significantly reduced disease pressure across several locations, while PGR application reduced the disease severity to a very limited extent. In some locations, combining the treatments reduced the disease and improved the turf quality compared to non-treated plots or when only one treatment was applied. Based on the observations, dew removals early in the morning can reduce the disease pressure more effectively. Regarding turfgrass quality, cultural practices improved the quality in most locations where nitrogen application showed a higher impact on quality enhancement, followed by PGR application, and lastly dew removal. Overall, the N application had the most notable impact on reducing the disease and enhancing the quality, while the effectiveness of dew removal and PGR varied depending on the location and other factors."
