Speed and performance made original SpeedZone the #1 speed herbicideand now its even better. SpeedZone EW Broadleaf Herbicide for Turf features an advanced emulsion-in-water (EW) formulation that delivers more complete coverage of the weed surface than original SpeedZone for rapid control of 90+ broadleaf weeds, plus goosegrass and nimblewill, and a lower odor profile and lower Volatile Organic Content (VOC). And the EW formulation is engineered for use in low-volume and conventional sprayers.
