Yes. SpeedZone weedicide contains a surfactant to help the glyphosate flow more easily into leaf cells and be absorbed into the leaf tissue. The herbicide manufacturer recommends using SpeedZone Weed Management Plus (POWM) as a surfactant with SpeedZone Weed Control, in foliar application rates of up to 7 ounces per acre (1.7 liters). There are three strengths of POWM: POWM-50, POWM-100, and POWM-200.
