Sedgehammer Plus Nutsedge Killer
Sedgehammer Plus Nutsedge Killer
Sedgehammer Plus is a selective herbicide that provides excellent post-emergent control over yellow nutsedge, purple nutsedge, and other tough broadleaf weeds in lawns, turfgrass, and landscaped areas. Comes in a convenient single-use pack with added surfactant.
10/21/24
Sedgehamme Plus, manufactured by Gowan, is a selective, post-emergent herbicide formulated with halosulfuron-methyl to control nutsedge and other broadleaf weeds.
Sedgehammer Plus comes in pre-measured packets for treating smaller areas. Each packet has a surfactant mixed in with the product and can treat 1,000 square feet. The active ingredient is 5% halosulfuron-methyl.
This herbicides delivers effective control of weeds and sedges and is safe for lawns. When applied to the leafy tissue of targeted weeds, the solution moves down to the roots to eliminate the plant. Sedgehammer Plus is ideal for use in residential, commercial, and industrial areas.
Tools Needed
You will need a backpack sprayer, hand pump sprayer, or professional spray rig to make applications. We recommend using a hand pump sprayer for small-volume areas.
How to Use
- Step 1: Determine how much Sedgehammer Plus to use by measuring the square footage of the treatment area. You can do this by measuring the length and width of the treatment area in feet, and then multiplying them together (length X width = square footage). For post-emergence control of purple or yellow nutsedge, Kyllinga and broadleaf weeds mix 0.5 ounce (13.5 grams) of this product (one pouch) in one gallon of water to treat 1000 square feet. For post-emergence control of horsetail (Equisetum arvense) apply 1 ounce (27 grams) of this product (two pouches) per 1000 square feet after horsetail has leafed out.
- Step 2: Fill your spray tank with half the amount of water, then add the Sedgehammer Plus. Pour the remaining half of the water and stir or shake thoroughly.
- Step 3: Apply your mixed solution. On a fan spray setting, spray the target weeds thoroughly until wet, but not to the point of runoff. A second treatment may be needed 6 to 10 weeks after your initial treatment. For best results, do not mow turf 2 days before or 2 days after application.
Where to Use
Sedgehammer Plus can be applied to nutsedge and other weeds in established lawns, ornamental turfgrass, landscaped areas, commercial and residential turf and on other non-crop sites including airports, campgrounds, cemeteries, fairgrounds, fence rows, fallow areas, fuel storage areas, golf courses, landscaped areas, established woody ornamentals in landscape areas, lumberyards, public recreation areas, race tracks, residential property, rights-of-way, roadsides, school grounds, sod or turf seed farms, sports fields, tank farms and tennis courts.
Do not apply either of these products to golf course putting greens, and do not spray over the top of desirable flowers, ornamentals, vegetables, shrubs, trees, or vascular plants.
When to Use
Apply when weeds are actively growing and have emerged from labeled sites.
These products can be applied when the turf has not been mowed for at least 2 days before application and should not be mowed 2 days after application. Do not use these products when rainfall is forecasted within 4 hours of application.
When controlling nutsedges, do not apply if either the turfgrass or nutsedges are under stress.

Keith's Pro Tips | "Nutsedge has a root system made with tubers, also known as nutlets. Every time the root system is broken, a new sprout appears. This means that when nutsedge weeds are pulled without the entire root system, more grows in its place, causing the problem to worsen." |
Product Drawbacks | Sedgehammer will damage vascular plants, such as ferns or tomato plants. When applying Sedgehammer be sure to avoid over spray on vascular plants by using a cone on the spray wand or covering non-targeted plants. |
