Best Product To Kill Nutsedge for Established Lawns

#1 · Best Overall

1. Sedgehammer Plus Turf Herbicide

• Weight: 27.22 g
• Form: Powder

Best for: Tubers-and-nutlets turf control.

Why it ranks #1: Controls yellow and purple nutsedge above and below ground, including tubers and nutlets, and is listed for several established turf types.

Control that reaches nutsedge below ground is the key feature of Sedgehammer Plus: it targets rhizomes, tubers, and nutlets as well as above-ground growth. The two-pack contains water-mix powder for selective post-emergent treatment of purple and yellow nutsedge in established turf.

Each supplied packet is a powder that you mix with water, giving buyers a measured format for preparing a spray rather than applying a ready-to-use liquid. Its selective action is listed for established turf including St. Augustine, Bermuda, Zoysia, Centipede, Bahia, Buffalograss, and Kentucky bluegrass, among others. The stated timing is gradual: leaves usually yellow in 10 to 14 days, with full results in three to four weeks. Do not add non-ionic surfactant, and use mixed solution within 24 hours.

Skip it if you want a ready-to-use spray without mixing; Ortho Max Nutsedge Killer RTU comes ready to apply.

A fit for lawn owners willing to mix a selective treatment to target nutsedge below ground, especially where established turf matches the listed grasses. Account for the stated multiweek results timeline and short mixed-solution storage window.

#2 · Highest Coverage

2. PBI-Gordon Arkon

• Weight: 2.3 lb
• Form: Liquid

Best for: Large-area concentrate treatment.

Why it ranks #2: The 32-fluid-ounce concentrate treats up to 26,600 square feet and targets nutsedge and kyllinga tubers and roots.

A 32-fluid-ounce concentrate listed to treat 26,600 square feet makes Arkon notable for larger lawn areas. Its selective post-emergent formula targets nutsedge, nut grass, and Kyllinga down to tubers and roots, with listed compatibility for Bermuda, Zoysia, fescue, and bluegrass.

The concentrate is mixed at 1.2 to 1.7 fluid ounces per 1,000 square feet and applied with a sprayer, so buyers can scale batches to the treatment area. The listed coverage of up to 26,600 square feet helps estimate how much lawn the container can address. For hard-to-control weeds, directions specify two applications at the 1.2-ounce rate, spaced 30 days apart. Its root-and-tuber focus complements the listed selective use on several common turf types.

Skip it if you need a ready-to-use product rather than a measured concentrate; Ortho Nutsedge Killer RTU skips concentrate dilution.

Arkon fits buyers treating a substantial lawn area who can measure concentrate and apply it with a sprayer. Consider the stated repeat-application schedule for hard-to-control weeds and confirm your turf is among the listed types.

#3 · Best Single Packet

3. Sedgehammer Nutsedge Herbicide

• Weight: 3.2 oz
• Form: Liquid

Best for: Measured coverage with surfactant.

Why it ranks #3: Its 1.33-ounce pack controls yellow and purple nutsedge down to tubers and nutlets; one packet is listed to cover 1,000 square feet.

A supplied scoop and explicit coverage rate make this Sedgehammer concentrate easier to portion for a known lawn area: one level 0.9-gram scoop treats 1,000 square feet when mixed as directed. It targets nutsedge above and below ground, including the tubers and nutlets that drive regrowth.

The directions call for one level scoop and two teaspoons of non-ionic surfactant per gallon of water, providing a defined recipe for a 1,000-square-foot treatment. The surfactant is specified to help the spray adhere to leaves, connecting the mixing step to application coverage. This selective post-emergent formula contains 75% halosulfuron-methyl and targets purple and yellow nutsedge down to tubers and nutlets. Leaves usually yellow in 10 to 14 days, with full results in three to four weeks.

Skip it if you want a spray that needs no surfactant; Ortho Max Nutsedge Killer RTU is ready to use without mixing.

Choose this Sedgehammer when a measured rate and defined lawn coverage help plan treatment. It suits buyers prepared to add the specified surfactant and wait several weeks for the stated full-results timeline.

#4 · Best Premeasured Mix

4. Atticus Empero Q-Pak

• Weight: 13.5 g
• Form: Water Dispersible Granular

Best for: Premeasured turf-treatment packets.

Why it ranks #4: Two premeasured packets contain 5% halosulfuron-methyl, mix with one gallon of water each, and are intended for established warm- or cool-season turf.

Premeasured water-dispersible packets simplify dosing: add one packet to a sprayer and mix with one gallon of water. Atticus Empero uses 5% halosulfuron-methyl and targets nutsedge down to the tubers, with use listed on many established warm- and cool-season lawns.

The packet format avoids measuring loose concentrate for each gallon, while the directions provide a clear preparation sequence: add one packet to a sprayer, mix with a gallon of water, and apply to the affected area. Its rootward action targets tubers, and the listed turf fit includes bluegrass, fescue, Bermudagrass, and zoysia, among other established grasses. Because it is a spray solution, allow treated areas to dry before pets or people return, as directed in the safety information.

Skip it if you need to adjust small batch sizes; Atticus Empero concentrate includes a scoop for measuring granules.

Consider this Empero packet option for established lawns where its listed turf compatibility fits and a premeasured gallon batch is convenient. The application requires a sprayer and treated areas must dry before access resumes.

#5

5. Atticus Empero Concentrate

• Weight: 1.33 oz
• Form: Granule

Best for: Measured concentrate for lawn batches.

Why it ranks #5: The 1.33-ounce concentrate contains 75% halosulfuron-methyl and mixes with water for root-level control on many established turf types.

A 1.33-ounce bottle with a scoop gives this Empero concentrate a measured, mix-at-home format for treating nutsedge down to its root-system tubers. Its 75% halosulfuron-methyl formula is listed for many established warm- and cool-season lawns, including bluegrass, fescue, Bermuda, and zoysia.

Unlike a premeasured single-gallon packet, this bottle-and-scoop format lets you measure granules for mixing, which may suit buyers preparing their own spray batches. The product description says the granules dissolve rapidly in water and that the treatment travels down to the root system tubers. Its stated turf compatibility covers many established warm- and cool-season grasses, including bluegrass, fescue, Bermudagrass, and zoysia. The supplied facts do not specify a treatment rate, so consult the product label for mixing directions.

Skip it if you prefer a packet with a specified gallon batch; Atticus Empero Q-Pak calls for one packet per gallon.

This concentrate suits lawn owners who want a scoop-measured granule format and have established turf among the listed grasses. Check the label for the mixing rate and ensure the application method fits your equipment.

#6 · Best Ready-to-Use Pair

6. Ortho Max Nutsedge Killer RTU

• Weight: 8 oz
• Form: Liquid

Best for: Ready-to-use lawn spot treatment.

Why it ranks #6: Two 24-ounce ready-to-use bottles kill yellow and purple nutsedge and are rainproof in two hours, with no mixing required.

Ready-to-use liquid in a two-pack removes the mixing step, so you can apply directly to yellow or purple nutsedge, Kyllinga, and other listed weeds. Ortho says it is rainproof in two hours and intended for Northern and Southern turf grasses, giving lawn owners a straightforward option for targeted treatment.

The ready-to-use format means there is no concentrate-to-water measuring before application, which simplifies small lawn jobs and spot treatments. Its listed weed control includes yellow and purple nutsedge, Kyllinga, and more than 50 other tough weeds, while the product claims to kill weeds, not lawns. The Northern and Southern turf-grass compatibility broadens its stated lawn fit. Rainproofing in two hours is a practical timing consideration: apply when that window can remain clear.

Skip it if you need a stated coverage area before choosing; this listing gives no per-container treatment area.

A practical match for lawn owners who want ready-to-use nutsedge control across Northern or Southern turf and value a simple application. Check that the two-hour rain-free window and the listed turf compatibility suit your lawn.

#7

7. Ortho Nutsedge Killer RTU

• Weight: 0.69 kg
• Form: Spray

Best for: Precise spot-spray applications.

Why it ranks #7: The 24-ounce spray is ready to use for direct weed application and lists selective control of yellow and purple nutsedge.

A spray bottle for direct application is the defining convenience here, letting you target unwanted weeds in lawns, gardens, and landscaped areas without treating an entire space. Ortho lists yellow nutsedge and nutgrass among the targets, and describes selective herbicide action for lawn weed control.

The spray format supports precise weed-by-weed application, a useful fit for scattered nutsedge or other listed weeds in lawn and landscaped settings. Directions call for spraying directly onto weeds on a calm day while they are actively growing, and avoiding desirable plants. The listing also describes the formula as a concentrate, but does not provide a mixing ratio in the supplied facts. That makes the product's direct-spray workflow clearer than its concentrate details; follow its label directions.

Skip it if you need a clearly specified concentrate dilution; Ortho Max Nutsedge Killer RTU spells out a no-mixing format.

Choose this Ortho when precise spraying of individual weeds across lawn or landscaped areas is the priority. Its calm-day application guidance matters, and the supplied information leaves the concentrate mixing details unspecified.

#8

8. Ortho Nutsedge Killer RTS

• Weight: 5 lb
• Form: Liquid

Best for: Two-pack hose-ready lawn coverage.

Why it ranks #8: Two 32-ounce ready-to-spray containers target yellow and purple nutsedge, kyllinga, and over 50 other tough weeds.

Two 32-ounce ready-to-spray containers provide a convenient hose-application format for treating listed lawn weeds. Ortho identifies yellow and purple nutsedge, Kyllinga, and more than 50 other tough weeds, and states compatibility with Northern and Southern turf grasses.

The ready-to-spray format removes concentrate measuring and mixing from the application workflow, while the two-container bundle supplies two units for lawn treatment. Its listed targets include yellow and purple nutsedge, Kyllinga, and more than 50 other tough weeds, making it relevant when several weed types are present. The product claims to kill weeds, not lawns, and to become rainproof in two hours. Avoid application when rain is expected during that period, as the safety information directs.

Skip it if you need a stated area-per-container figure; PBI-Gordon Arkon lists coverage up to 26,600 square feet.

This two-pack suits lawn owners seeking a ready-to-spray option for nutsedge and other listed weeds on Northern or Southern turf. Its two-hour rainproofing window and unspecified container coverage are useful planning boundaries.

#9

9. Image Crabgrass Nutsedge Killer

• Weight: 1.6 lb
• Form: Liquid

Best for: Hose-end broad weed coverage.

Why it ranks #9: The 24-fluid-ounce lawn product targets yellow and purple nutsedge alongside crabgrass and more than 100 other listed weeds.

Hose-connected spraying makes this Image liquid a convenient choice for lawn owners treating more than nutsedge. It starts working on contact and lists crabgrass, yellow and purple nutsedge, dandelion, clover, and more than 100 other weeds, while claiming not to harm grass when used as directed.

The ready-to-spray format connects to a hose, avoiding the separate mixing workflow of concentrates and supporting treatment across established lawn areas. Its broad list includes crabgrass, nutsedge, dandelion, chickweed, dollarweed, and clover, so one application can address multiple listed weed types. The product also says it starts working on contact and kills tough weeds to the root. Because the grass-safety claim is conditional on use as directed, follow the label and apply only to appropriate lawns.

Skip it if you want a hand-sprayed ready-to-use bottle; Ortho Nutsedge Killer for Lawns Ready-to-Use comes in a spray format.

A sensible fit for lawn owners who want hose-connected treatment for nutsedge plus a broad range of listed weeds. Its application depends on a hose, and the lawn-safety claim applies only when used as directed.

#10

10. Ortho Nutsedge Weed Killer

• Weight: 2 lb
• Form: Liquid

Best for: Basic Ortho nutsedge option.

Why it ranks #10: This product is identified as a liquid nutsedge weed killer, but its supplied details provide few differentiating use or coverage specifications.

This Ortho liquid is identified as a nutsedge weed killer, with safety information specifying application to weeds under three inches high on dry lawns. That guidance gives buyers a clear height and lawn-condition boundary, though the supplied listing provides few further product details.

The available information identifies the product as a liquid and says to apply it to weeds when they are less than three inches high, on dry lawns. It also states rainproofing in two hours and advises avoiding contact with flowers, ornamentals, garden vegetables, and unlisted turfgrasses. Those directions help define when and where application is appropriate. The supplied facts do not describe a container application mechanism or give a mixing rate, so consult the label for the complete application procedure.

Skip it if you need a clearly described spray format; Ortho Nutsedge Killer for Lawns Ready-to-Spray specifies its application type.

This may suit buyers seeking an Ortho liquid nutsedge product who can follow its height and dry-lawn directions. The sparse supplied details make checking the label important for application method and full usage instructions.
