SEDGEHAMMER® + is a selective herbicide for post-emergence control of sedges such as purple and yellow nutsedge in established lawns, ornamental turfgrass and landscaped areas. SEDGEHAMMER+ can be used to selectively control Kyllinga species and certain broadleaf weeds. For optimum results it is best to apply SEDGEHAMMER® to young, actively growing nutsedge plants (plants that have emerged within the last 6 weeks).
