Abstract/Contents:"Wetting agents play critical roles in water management and conservation on golf courses. Yet label guidelines can be vague and inconsistent. Certain products claim to provide season long effectiveness from a single application, while others endorse calendar-based reapplication intervals. Even for a single product, application rates and timings can vary greatly. There is a need to investigate how different application strategies impact product performance. The objective of this research was to compare six different wetting agent products, using five different application strategies, in terms of volumetric water content and turfgrass quality. The study was conducted in Fayetteville, AR on a sand-based, creeping bentgrass (Agrostis stolonifera L. L"93") green. The trial was a two-factor, split-plot design, arranged in a randomized complete block with four replications. Wetting agent product served as the whole-plot factor and included six treatment levels: Cleanse, Distance (both Target Specialty Products, Santa Fe Springs, CA), Dispatch (Aquatrols, Paulsboro, NJ), Magnus (Precision Labs, Waukegan, IL), PBS150 (AquaAid Solutions, Rocky Mount, NC), Tricure (Mitchell Products, Millville, NJ). Within each product, split-plots consisted of an untreated control and five different application strategies: single application at the label rate, single application at twice the label rate, monthly applications at the label rate, monthly applications at half the label rate, and applications repeated every two months at the label rate. Volumetric water content was measured at 3.8 and 7.6 cm using time domain reflectometry.Turfgrass quality was assessed through visual ratings (1-9 scale) and digital image analysis. Repeated monthly applications at label rates led to improved turfgrass quality, compared to other strategies. Repeated monthly applications at half rates also showed greater turfgrass quality and coverage compared to single applications. Developing reapplication intervals that reflect environmental conditions such as growing degree days or evapotranspiration may further improve wetting agent performance."
