Sulfentrazone 4SC Select

Sulfentrazone 4SC Select with 39.6% Sulfentrazone is both a pre and post emergent, selective herbicide. Apply Sulfentazone 4 SC to get rid of broadleaf, grass, and sedge weeds in established turf in both warm and cool-season turfgrasses. Use Sulfentrazone in turfgrasses such as bahiagrass, buffalograss, carpetgrass, centipedegrass, kikuyugrass, zoysiagrass, bermudagrass, bentgrass, fescue, ryegrass, and bluegrass turfs. It controls tough weeds such as black medic, pigweed, spurge, barnyard grass, crabgrass, foxtail, goosegrass, chickweed, groundsel, carpetweed, clover, dandelion, dollarweed, ground ivy, henbit, plantain, kyllinga, and nutsedge.

Sulfentrazone 4SC Select is a flowable herbicide that provides visible results in 24-48 hours. For best control of broadleaf weeds, apply Sulfentrazone 4 SC just after weed emergence when the weeds are actively growing and are small.
