Sulfentrazone 4SC Select is a soil-applied selective, flowable herbicide that contains 4 pounds of active ingredient per gallon. Sulfentrazone 4SC Select can be used to control broadleaf, grass, and sedge weeds in established turfgrasses (seeded, sodded, or sprigged). Best control is achieved with grassy weeds when applied to grasses that are actively growing and small (pre- tiller stage). For optimum control of broadleaf weeds, applications should be made shortly after emergence.
