SedgeHammer Herbicide

We highly recommend using a surfactant with Sedgehammer 1.33 ounce bottle.

Sedgehammer in the 13.5 gram box already contains surfactant.

SedgeHammer herbicide kills nutsedge without injury to turfgrass, established ornamentals, shrubs, and/or trees. SedgeHammer provides post-emergence control of both purple nutsedge and yellow nutsedge. SedgeHammer also controls many broadleaf weeds and suppresses kyllinga. Nutsedge is controlled after emergence in cool and warm season turf grasses such as St. Augustinegrass, Bermudagrass, Kentucky Bluegrass, tall and fine fescue, and perennial ryegrass. Sedgehammer is considered one of the more "gentle to turfgrass" products and pets and people can return to the treated area once the spray dries.

Sedgehammer is the exact same product as Manage Herbicide. The Gowan Company purchased the Manage product and its rights to use from Monsanto in early 2005 and now sells the very same product as Sedgehammer.

How SedgeHammer Herbicide Works

SedgeHammer is a water-soluble granule formulation that is mixed with water and applied to target plants with a sprayer. SedgeHammer is a member of the sulfonylurea family, an ALS (acetolactate) enzyme inhibiting herbicide. The active ingredient is absorbed into leaf tissue as quickly as 24 to 48 hours after application, then translocated through the plant’s vascular system. The herbicide quickly inhibits amino acids, halting cell division and plant growth in both roots and shoots, causing eventual death in target plants.

A nonionic surfactant is an additive that aids the penetration of SedgeHammer into the plant tissue. Surfactants are not only used in horticulture but are commonly used in many cleaning products. Their properties enable the herbicide to “sheet” or spread across the surface of a plant or weed. It is always recommended that a surfactant be used to help SedgeHammer penetrate the waxy layer of the nutsedge leaf. The surfactant also aids in dispersing the water droplets evenly across the leaf tissues and facilitates adsorption into the vascular system of the plant.

SedgeHammer Target Weeds

Purple Nutsedge, Yellow Nutsedge, Kyllinga

WEEDS CONTROLLED WITH SEDGEHAMMER: Purple Nutsedge, Yellow Nutsedge, Green Kyllinga, Annual Kyllinga, Cocklebur, common Sunflower, common Ragweed, giant Ragweed, Pigweed, Velvetleaf, Horsetail

Additional weeds controlled with SEDGEHAMMER+ (small packets) only: Burcucumber (suppression), Corn Spurry, Rice Flatsedge, Philadelphia fleabane, Galinsoga, common groundsel (preemergent only), Jimsonweed (preemergent only), Kochia (suppression), Ladysthumb, common Lambsquarter (preemergent only), Venice Mallow (suppression), common Milkweed (suppression), honeyvine Millkweed (suppression), Morningglory (suppression), wild Mustard, redroot Pigweed, smooth Pigweed, common Poweweed, Purslane (preemergent suppression), wild Radish, Shepherds purse (suppression), Pennsylvania Smartweed

Target Uses of SedgeHammer

SedgeHammer Herbicide is a selective, post-emergent herbicide concentrate designed specifically to kill nutsedge and other broadleaf weeds without injury to turfgrasses, established ornamentals, shrubs, or trees. SedgeHammer can be used in both warm-season and cool-season turfgrasses, landscaped areas, and other non-crop areas.

SedgeHammer will not prevent germination of most labeled target weeds. Rather, it should be applied to actively growing weeds. If turfgrass or nutsedge is under stress, poor control may result. Also, desirable turfgrass, ornamentals, and trees should be well established before application. Do not apply to edible plants or gardens.

*Note that weeds can develop resistance to herbicides. To minimize the potential for resistance development and/or to control resistant weed biotypes, use a variety of cultural, mechanical, and chemical weed control tactics. Rotate with herbicides having other modes of action.

ACTIVE INGREDIENT: 1.33 oz. bottle - Halosulfuron-methyl 75%; 13.5 g package – Halosulfuron-methyl 5%

SedgeHammer Application Instructions

SedgeHammer is a powder concentrate to be diluted with water and applied with a pump sprayer. SedgeHammer should not be applied with hose-end sprayers since they are far less accurate than hand pump sprayers. When applying, spray the weeds thoroughly and wet the entire leaf surface of the undesirable plants. For best results, spray nutsedge after it has reached the 3 to 8 leaf stage of growth.

SedgeHammer often works with one application, but depending on the size and age of the nutsedge a second treatment may be required 6 to 10 weeks after the initial treatment. See “Other Tips” below for more information.

Mixing Instructions, 1.33 oz container:

Using included spoon, measure .9 grams (one spoonful) and pour into 1 gallon of water. Measure level scoops only (not rounded).

*Swirl or mix the solution thoroughly.  The 0.9 grams will cover 1000 sq. ft. One full bottle (1.33 oz.) makes approx. 40 gallons of finished solution.
*Add 2 teaspoons of a nonionic surfactant (spreader sticker) and swirl gently until mixed.

For best results, add a surfactant that is specifically made for horticultural purposes and labeled for use with an herbicide. Use only surfactants that contain at least 80 percent active material. Do not exceed the recommended amount of surfactant due to potential turf injury at higher rates.

*While spraying, periodically swirl or shake the mixture to keep the product evenly distributed in the water.
*Do not store the mixed solution as it will degrade and become ineffective.

The 13.5 gram packets already contain a surfactant, so you only need to mix the contents of the packet itself with a gallon of water. See below for further details. Always read the product label completely before use.

Each 13.5 g packet makes 1 gallon of finished solution and already contains a surfactant. Each 1.33 oz. bottle makes 40 gallons of finished solution. Each gallon of finished solution covers approximately 1,000 square feet. In high volume broadcast applications, each 1.33 oz. bottle covers 1-2 acres.

Standard Application Dilution rates / Mixing Ratios for SedgeHammer:

*13.5 g packet – Entire contents of 1 packet (0.5 oz.) per gallon of water – Ideal for spot treatments
*1.33 oz. bottle – Use 0.9 g (one spoonful) in 1-2 gallons of water with 2 teaspoons of a nonionic surfactant – More economical for broadcast applications

Broadcast applications (1.33 oz. bottle only):

*2/3 oz. in sufficient water for uniform application per acre – light infestations
*1 1/3 oz. in sufficient water for uniform application per acre – heavy infestations
*Do not exceed 4 applications per acre per season. Do not exceed 1 quart of surfactant per acre. Mix only what is needed at the time of application. Do not store unused solution.

SedgeHammer is for use in the following areas:

Commercial and residential turf and other non-crop sites including: airports, cemeteries, fallow areas, golf courses, landscaped areas, public recreation areas, residential property, roadsides, school grounds, sports fields, landscaped areas with established woody ornamentals, fairgrounds, race tracks, tennis courts, campgrounds, and rights-of-way

Tolerant Turfgrasses – Cool-Season: creeping Bentgrass, Kentucky Bluegrass, fine Fescue, tall Fescue, perennial Ryegrass; Warm-Season: Bahiagrass, Bermudagrass, Buffalograss (Sedgehammer+ only), Centipedegrass, Seashore pasapalum, St. Augustinegrass, Kikuyugrass, Zoysiagrass


SedgeHammer is not labeled for indoor use of any kind.


See general mixing instructions, mixing rates, and application details above.

Established woody ornamentals in landscaped areas – Apply as a post-directed spray. Avoid contact of this product to leaves of desirable plants since foliar injury, discoloration or death may result.

Horsetail Control – SedgeHammer + (small packets): Apply 1 oz. (27 g or 2 pouches) per 1,000 square feet after horsetail has leafed out. SedgeHammer (bottle): Apply 2 2/3 oz. per acre, or 1.8 g per 1,000 square feet.

This rate of product will control horsetail that is less than 6 inches tall and suppress horsetail that is greater than 6 inches tall. Herbicide symptoms are likely to show within 2 weeks as a necrotic ring at the base of the plant, even though the leaves and stems remain green and a deep leathery green in color.

    5 of 5 Stars  It works!
    By Charles in Bowling Green, Ohio on June 20, 2010

    I've been fighting nutsedge for several years using nutsedge and crabgrass control products. They were disgustingly ineffective. I read of other people's experience with SedgeHammer on a daylily web page and decided to try it. Two days after spraying, the nutsedge started turning brown. Of equal importance, the daylilies surrounding it did not. They show no evidence of ever being near an herbicide. Am I satisfied? You bet!

    5 of 5 Stars  Sedgehammer
    By Gary in Ozark, MO on July 16, 2010

    I hate nut grass. It has been a problem for me from my first yard. I have used Roundup with an eye dropper and even a hypodermic syringe to kill the stuff. Then a man recommended SedgeHammer. The price was a little frightening but my resolve was firm. I bought it from, received it promptly and used it with great success. The yellow nut grass began dying in 3 days and now is gone. I don't know if it will remain "gone", but I have enough of the stuff to "kill" it repeatedly.

    5 of 5 Stars  Sedgehammer - THE solution for nutsege
    By Len in Carrollton, VA on September 2, 2010

    This hot, dry summer we've been having here in Tidewater, Virginia has been awful for the fescue we grow here but perfect for nutsedge. My infestation was extensive. A few tips: Follow all the advice given in the instructions. Make sure the nutsedge has almost a week of growth on it; this is important. If the sedge is too small or you try to use it on a freshly cut lawn, the sedge won't have enough surface area to absorb sufficient herbicide to be effective. Also, make sure you sure use surfactent with the hebicide, it will help this very expensive chemical be absorbed more effectively by the sedge. Give the chemical time to work; the longer you can wait before mowing after application (I waited almost a week before mowing) the better the killoff. By that time (a week after application) I had an almost 95% killoff, the few live sedges were those few I had missed on the first application. One more application on the stragglers will finish the job.

    4 of 5 Stars  The Sedge Gets Hammered
    By Dennis in Yorktown, VA on July 7, 2010

    I have been using this product for several years, and have found it to be the most effective for control of sedge, particularly in beds and around ornamentals in combination with Roundup. Because I am blessed with rich soil, everything grows well - sedge too; so control of sedge is an ongoing battle. The granular form of the product is convenient and easy to measure with the included measuring spoon.

    5 of 5 Stars  SedgeHammer Works!
    By Angela in Philadelphia, PA on September 6, 2010

    Despite the fact that SedgeHammer is very expensive, I do not regret purchasing it because it WORKS! I bought the largest bottle which I think makes up to 40 gallons. So, I'll have enough to last me a few years. I recommend using an herbicide pump sprayer. I bought a Round-Up brand 2-gallon sprayer for $20 and it allows me to not waste as much SedgeHammer as I would if I used a watering can. I had A LOT of well-established sedge. About 7-10 days after the first application the sedge turned yellow and stopped growing and the grass was NOT harmed. I just did a second application because I had missed a lot sedge plants during the first application. This product is worth the $$.

  • 5 of 5 Stars  This is Good STUFF
    By Joe in Abilene, Texas on October 11, 2015

    This is the second season I have used SedgeHammer. We have had a bad Nutgrass problem for several years--have tried multiple remedies with little or no satisfaction. At the end of last summer, I used SedgeHammer--the Nutgrass literally disappeared. By July of this year, we again had a good Nutgrass crop. I tried a different product resulting in dead lawn areas and thriving Nutgrass. Used Sedgehammer again, Nutgrass disappeared again without damage to the lawn. I ran out, so have ordered enough to use when the Nutgrass becomes active again next spring. I hope two applications in the same season may end our Nutgrass.

  • 3 of 5 Stars  Guess You Have To Spray Twice
    By Bill in Garland, TX on September 26, 2015

    Sprayed our back yard earlier in the summer and we were so pleased that it seemed to eliminate the Nut Grass. But, this fall we have it all back. Read advice of our local garden expert here in Dallas, and he said you HAVE to spray again approximately 6 weeks after the first application. So ordered some more and I will try it again this coming spring and try spraying the yard twice.

  • 5 of 5 Stars  sedge hammer herbicide
    By Dan in Port Chester, NY on September 25, 2015

    The product works very well. I paid a lawn service company to rid my lawn of nutsedge and it did not do a good job. The sedge hammer was easy to apply and took out all the nutsedge. I bought enough for next season because I applied it too late in the season and was told it might return if the nut was not destroyed. You have to catch it early just as it begins to sprout to kill the nut. Great product , follow directions and you will get good results.

    By Jerry in TEXAS on September 18, 2015

    After doing a little research, for me, this was the best product I found. I had already (last year) tried ROUNDUP on an area about 10' X10'. That did an excellent job on my grass (Bermuda) but the "nut grass" took over about 2/3 of my yard. After using this product I expected the results to be about the speed of Roundup. Instead it took 10 to 11 days to see any results but today (15 days) I see dead and dyeing nut grass leaves everywhere. WITH NO DAMAGE TO THE GRASS (Bermuda) I WANT. I was careful to read ALL the instructions and follow carefully.

April 16, 2011 Ken asked:

QAfter I mix 2 gallons of Sedgehammer, how long will it remain effective?
I have my nutsedge down to a small area with only a dozen colonies so I mix 2 gallons and fill a one quart spray bottle for convenience. How long will the remaining liquid product remain effective?

ATypically it is not recommended to leave any pesticide solution in a sprayer for more than two weeks at a time.  You should only mix what you plan on using.  If you want to leave the product in the sprayer for longer you should at least shake and agitate the sprayer every few days to keep the solution from separating.

AAll the surfactants on our website are non-ionic which is the type of surfactant the manufacturer of SedgeHammer herbicide recommends for use with their product in the bottle size (1.33 oz). The 13.5 gram pack of SedgeHammer already includes a built-in surfactant.

QCan I use SedgeHammer to kill nutsedge right before sodding with St. Augustine?
I have bare soil (with nutsedge) right now and am planning to sod in the next 7-10 days. Or do I need to place the sod and then wait 4-6 weeks and go over it with the SedgeHammer?

APer the label on Sedgehammer, you are not supposed to reseed or sod within 3 to 4 weeks of using Sedgehammer.  Therefore you have only a couple of options.  One, is to treat the sedgehammer and stun it with a glyphosate (round up) type product which allows you to reseed within 7 days with no issues.  Or, you can treat with Sedgehammer and wait 3 to 4 weeks before re sodding.  If you must sod in 7 to 10 days, then you should treat the nutsedge with a glyphosate product and then you can treat with sedgehammer later if any new nutsedge makes it through the sod you are applying.

QWhat time of year is sedgehammer most effective?
Can it be used in the fall or the start of winter? How long do I have to wait before I can Plat a garden after applying sedge hammer?


Sedgehammer will only control weeds that are actively growing so it likely will not kill anyting in the winter once the plants are dormant and may only give partial control in the fall. It is best used in the warmer spring and summer months and early fall. Per the manufacturer, if you plan to plant a vegetable garden you cannot do so within 3 years of applying Sedgehammer in the same area unless you remove the soil treated with Sedgehammer and bring in fresh soil.

QCan I spray SedgeHammer Herbicide on my hayfield with timothy planted in it, and will it effect the hay feeding?
Also how much does the largest bottle make when mixed?


SedgeHammer Herbicide should not be used on pastures or grazing areas, and you should not treat around hay that will be used for animal feed. The SedgeHammer should not affect Timothy grass that may be contacted by the herbicide, although the product label does not specify information about this plant, so we would recommend spot treating a small area first before applying over a large area with this plant. The 1.33 oz bottle of SedgeHammer will yield about 40 gallons of finished solution. You should add 2 teaspoons of a non-ionic surfactant per gallon of water when diluting SedgeHammer from the larger bottle. The smaller packets already have a surfactant mixed in with the product.
