Celero® Herbicide is a selective, post-emergence herbicide for control of sedges including kyllinga in established residential and commercial turfgrass, golf courses and sod farms. Imazosulfuron, the active ingredient in Celero, is a systemic sulfonylurea (SU) herbicide that translocates down to the roots to deliver superior sedge control. Labeled for both broadcast and spot treatment in cool- and warm-season turf, Celero is the ideal solution for difficult-to-manage sedges.
