Sulfentrazone 4SC is a soil-applied selective, flowable herbicide that contains 4 pounds of acid ingredient per gallon. Sulfentrazone 4SC can be used to control broadleaf, grass and sedge weeds in established turfgrasses (seeded, sodded or sprigged), including residential and institutional lawns, athletic fields, golf course fairways and roughs, commercial sod farms and many non-crop and industrial sites. 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 weed emergence.

  • Visible results in 24-48 hours
  • Controls weeds both pre- and post- emergence
  • Tough on weeds, gentle on established turfgrass
    When Sulfentrazone 4SC has been activated, it will provide control of listed weed species. The level of control will depend on the size and type of weed species when Sulfentrazone 4SC is activated. The control of listed germinating weed species will be reduced when rain or irrigation follows a period of dry weather.

    Application Rates: Apply 8 - 12 fl. oz. / acre.  Sulfentrazone 4SC Select is mixed at the rate of 0.18-0.28 oz. per 1000 square feet. This is equivalent to 1-1.6 teaspoons. This will mix in approximately 1-2 gallons of water for spot treating in your Bermuda lawn.
