SEDGEHAMMER Plus Turf Herbicide is a selective herbicide designed to control nutsedge and broadleaf weeds in established lawns. Its active ingredient, halosulfuron-methyl, is quickly absorbed by leaves within 24 to 48 hours, moving to the roots and tubers for effective kill. Full results appear in 3 to 4 weeks, with yellowing of weeds in 10-14 days. The 13.5g packet contains a pre-measured concentrate with surfactant, requiring only mixing with 1 gallon of water to treat 1,000 sq ft. It is compatible with various turf types including Bermuda, Zoysia, and Kentucky bluegrass, and is suitable for home lawns, sports fields, golf courses (not greens), and roadside areas. Always follow label instructions for best results and safety.
Beyond nutsedge, it suppresses 19 other weeds like pigweed, ragweed, and galinsoga. For kyllinga, two applications are recommended. Use on actively growing weeds, avoiding spraying over flowers, vegetables, or trees. Watering isn't necessary post-application. For heavy infestations, repeat after 6-10 weeks, up to 4 times annually. Made in the USA, always read label directions before use.
