  • Selective post-emergent herbicide designed specifically to stop yellow and purple nutsedge.
  • Pre-measured packets with built‑in surfactant for easy mixing and improved absorption.
  • Safe for most warm- and cool-season turfgrass species when used as directed.
  • Controls nutsedge, kyllinga, and several tough broadleaf weeds without harming lawn grasses.

SedgeHammer Plus Nutsedge Killer provides professional‑grade, targeted control of yellow and purple nutsedge—two of the most persistent and fast‑spreading lawn weeds. Formulated with halosulfuron‑methyl and a built-in non‑ionic surfactant, this convenient ready-to-mix packet dissolves easily in water and delivers deep, systemic action to eliminate sedges at the root and tuber level. Ideal for use on residential and commercial lawns, landscaped areas, golf courses, and ornamental turf, SedgeHammer Plus offers reliable results where standard broadleaf herbicides fail. Its turf‑safe, selective chemistry makes it a trusted solution for restoring uniform, weed‑free lawns with minimal effort.


Key Benefits

Targets nutsedge at the root and tuber; selective and gentle on established turf; built‑in surfactant for superior leaf penetration; convenient pre-measured packet; effective on both purple and yellow nutsedge as well as kyllinga and select broadleaf weeds.

Effective Against

Yellow nutsedge, purple nutsedge, kyllinga species, cocklebur, annual sedges, rice flatsedge, smooth pigweed, galinsoga, ladysthumb, Philadelphia fleabane, and other labeled broadleaf weeds.

Where to Use

Residential and commercial lawns, golf courses, landscaped areas, ornamental turfgrass, and other non-crop turf settings where selective sedge control is needed.

Application Instructions

Mix one packet (13.5 g) in 1 gallon of water to treat 1,000 sq. ft.
Apply evenly to the foliage of actively growing nutsedge.
Avoid mowing 2 days before and after treatment.
Do not irrigate for several hours after application to allow absorption.
For heavy infestations, a second application may be made 6–10 weeks later.

Active Ingredient

Halosulfuron‑methyl – 5% (with integrated non‑ionic surfactant).

Performance Expectations

Initial yellowing typically appears in 7–14 days; complete control may take several weeks depending on growing conditions and weed density.

Safety Information

Safe for people and pets once dry. Avoid overspray on desirable ornamentals. Follow all label directions for mixing, application, and cleanup.

Covers & Packaging

Each packet treats 1,000 sq. ft. Pre‑measured for ease of use; no additional surfactant required.

Use Notes

Best applied to young, actively growing nutsedge. Works in warm- and cool-season turf including Bermuda, fescue, ryegrass, zoysia, St. Augustine, and centipedegrass when applied properly.

Active Ingredient:

Halosulfuron-methyl, methyl 3-chloro-5-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-1-methylpyrazole-4-carboxylate - 5.0%
