USGA Summary Points:Plant growth regulators (PGR) are commonly used on putting green turf to enhance performance to reduce the overall growth of the turf. In recent years, the application timing strategy has moved towards a growing-degree based model compared to calendar-based applications. PGRs have been shown to enhance plant performance in shaded environments, especially on warm-season grasses. A field study was conducted at two locations in 2021 and repeated in 2022 to compared different PGR application timings (calendar vs GDD) under 4 differing shade levels. At both locations, calendar-based applications of Primo Maxx have consistently produced higher quality under shaded conditions compared to a GDD application timing. Studies to investigate the effects of water quality on PGR efficacy were initiated in 2022, but the data has not been summarized to date.
