Abstract/Contents:"Wetting agents are a leading strategy for managing water on golf courses, yet superintendents express confusion about product labels. Multiple application rates and intervals are often listed, however differences between them are not well-documented. Improved understanding of application strategies could help optimize wetting agent performance, leading to potential savings in both water and cost. The objective of this research was to compare different application rates and intervals, across multiple wetting agents, in terms of volumetric water content (VWC) and turfgrass quality. The study was conducted in Fayetteville, AR on a sand-based, creeping bentgrass (Agrostis stolonifera L. "Tyee") putting green. It was a split-plot design, arranged as a randomized complete block with four replications. Wetting agent product was the whole-plot factor, with six treatment levels, each representing a different manufacturer: Brilliance (Simplot), Cascade Tre (Precision Labs), Distance (Target Specialty Products), PBS 150 (Aqua-Aid Solutions), Revolution (Aquatrols), Tricure (Mitchell Products). The combination of application rate and interval was the split-plot factor, so that each wetting agent was applied six different ways: season-long application at a standard rate, season-long application at a high rate, recurring monthly applications at a standard rate, recurring monthly applications at a reduced rate, recurring applications every two months at a standard rate, and non-treated control. Weekly data were collected for VWC using portable moisture meters (3.8 and 7.6 cm depths), visual ratings for turfgrass quality (1-9 scale) and percent localized dry spot (LDS). Significant split-plot effects were observed both above and below ground, with differences in 7.6 VWC occurring 21 days prior to differences in LDS. Additionally, monthly reduced rate and bi-monthly treatments exhibited significantly less LDS than non-treated control, indicating potential for cost savings. Based on significant differences among wetting agent products, future research should consider the importance of moisture uniformity, in addition to average VWC."
