| Abstract/Contents: | "Wetting agents are a primary management strategy utilized by most golf courses in putting green water management. Adding wetting agents can reduce the surface tension of water and overall soil repellency, thus allowing water to better infiltrate and percolate through potentially hydrophobic soils. However, physiological mechanisms of wetting agents' impact on turfgrass performance under drought stress have not been well understood. The objective of this study was to investigate physiological and root viability responses to wetting agent application in creeping bentgrass putting greens during summer stress. The study was conducted at the Virginia Tech Turfgrass Research Center in Blacksburg, VA, during 2021-2022 on a creeping bentgrass putting green managed as a standard golf putting green turf with regard to mowing, fertility, and surface irrigation. There were two treatments: HydroMAX surfactant Fleet 100 and an untreated control and each treatment was replicated four times in a randomized block design. Fleet100 was applied at 1.6 mL m-2 monthly. The grass was exposed to two dry-down cycles during mid-June and mid-July by withholding supplemental irrigation. Monthly application of Fleet100 at 1.6 mL m-2 significantly improved turf quality, leaf color ratings, leaf proline content, and chlorophyll content when compared to the control in creeping bentgrass putting greens, especially during drought stress periods. The creeping bentgrass treated with Fleet100 had greater root biomass and viability relative to control. The Fleet100 treatment also improved soil moisture content at 15 cm depth during drought stress period. The results of this study suggest monthly application of the wetting agent Fleet100 could improve drought tolerance associated with proline metabolism and root viability in creeping bentgrass putting greens." |
