Hydro-90 is a soil surfactant designed for use on turfgrass and ornamentals. Once in the root zone, Hydro-90 helps reduce soil water repellency, a cause of localized dry spot (LDS). When used as directed, Hydro-90 will help to improve the infiltration and overall movement of water in the root zone. Hydro-90 is readily soluble in water and can be applied with conventional application equipment. Apply Hydro-90 early in the season prior to the onset of stress. Do not apply Hydro-90 to turf and ornamentals under stress.
