Scepter T&O 70 WDG is a selective herbicide containing 70% imazaquin. It is designed for use on established lawns of Bermudagrass, St. Augustinegrass, Centipedegrass, and Zoysiagrass, as well as on golf courses, sod farms, commercial and residential turf, and selected landscape ornamentals. It controls a wide variety of weeds, including certain grasses, sedges, and broadleaf weeds such as crabgrass, nutsedge, dandelion, and clover. The product is applied as a water-dispersible granule (WDG) that is mixed with water and sprayed. It is effective against summer weeds and can be used for postemergence control of certain weeds in warm-season turfgrasses. Note that application timing is critical for certain weed types, and users should follow specific directions for weed resistance management. Always avoid application during temperature inversions or high wind speeds to prevent drift.
