SedgeHammer + Herbicide kills nutsedge without injury to turfgrass, established ornamentals, shrubs, and/or trees. SedgeHammer + provides post-emergence control of both purple nutsedge and yellow nutsedge. SedgeHammer + also controls many broadleaf weeds and suppresses kyllinga. Nutsedge is controlled after emergence in cool and warm season turf grasses such as St. Augustinegrass, Bermudagrass, Kentucky Bluegrass, tall and fine fescue, and perennial ryegrass. Sedgehammer + is considered one of the more “gentle to turfgrass” products and pets and people can return to the treated area once the spray dries.
The “+” in SedgeHammer + indicates that it already contains a surfactant, so it is not necessary to use any additional products. One 13.5 gram packet will treat 1,000 sq. ft.
How SedgeHammer + Herbicide Works
SedgeHammer + is a water-soluble granule formulation that is mixed with water and applied to target plants with a sprayer. SedgeHammer + is a member of the sulfonylurea family, an ALS (acetolactate) enzyme inhibiting herbicide. The active ingredient is absorbed into leaf tissue as quickly as 24 to 48 hours after application, then translocated through the plant’s vascular system. The herbicide quickly inhibits amino acids, halting cell division and plant growth in both roots and shoots, causing eventual death in target plants
