Abstract

A study was conducted at New Mexico State University during the summer months of 2003 and 2004 to investigate the effects of several wetting agents on sand-based rootzone hydrophobicity and putting green turf appearance. The efficacy of wetting agents varied over depth and was most pronounced at depths of 2.5 cm or less. All treated plots with the exception of Naiad and Respond 2 plots exhibited lower water repellency than the untreated plots at a depth of 0.5 cm. Plots treated with Aqueduct and LescoFlo showed consistently lower water repellency at rootzone depths of 0.5, 1.5, and 2.5 cm than the untreated plots. Naiad-treated rootzones exhibited greater hydrophobicity at depths of 0.5, 1.5, 2.5 and 3.5 cm compared to the untreated rootzones. In 2003 plots treated with Brilliance, Cascade Plus, HydroWet, LescoFlo, and Primer Select had higher turfgrass quality than the untreated plots, while Naiad-treated plots showed lower quality and color ratings than other plots. There were no differences in color or quality, among the treatments in 2004.
