Halosulfuron Pro Herbicide

Halosulfuron Pro is the same product as Sedgehammer, but cheaper. Same active ingredient and effectiveness.

We highly recommend using a surfactant with Halosulfuron Pro.
Halosulfuron Pro herbicide kills nutsedge without injury to turfgrass, established ornamentals, shrubs, and/or trees.  Halosulfuron provides post-emergence control of both purple nutsedge and yellow nutsedge.  Halosulfuron Pro 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.  It is considered one of the more "gentle to turfgrass" products and pets and people can return to the treated area once the spray dries.

Halosulfuron Pro is the exact same product as Manage Herbicide and Sedgehammer.

    5 of 5 stars  It works!
    By Kevin in Reading, Pa. on 08/22/2011
    Verified Purchase

    Just as advertised, it works - even though it is the generic version of Sedgehammer. Follow the directions as indicated on the package, and just use Jet Dri (for dishwashers) as your surfactant - works just fine. Just have to be paitient with it. I didn't see any yellowing for almost a week. But what I did notice is that the day after I sprayed, I took notice that the Nutsedge wasnt growing anymore - and we all know how fast that stuff can grow. Might have to give a 2nd shot to some of them. Not sure if I missed them the first time around or that it just didnt have an effect on some, but the ones that I did have to give a 2nd shot to only counts as about 1%. Pretty awesome stuff and it didnt hurt my grass at all.

    This product works perfectly. Just mix it with two gallons of water and some kitchen soap liquid. Spray it on on in ten days the impossible nut grass turns brown. Unbeleivebale. I highly recommend it

    5 of 5 stars  Halosulfuron Herbicide (Sedge Hammer)
    By Larry in Cincinnati, OH on 08/15/2011
    Verified Purchase

    Only product I have found that kills nut sedge in one application. Even Round Up sometimes doesn't do it. When I make up the gallon I save a "windex" size spray bottle of the solution to go back over the plants that I missed on the first spraying. The generic works just a good as the original for half the price.

    By Steve in Martinsville, IN on 08/23/2011

    Really worked well on my nutsedge problem. It takes a few days before the weeds begin to yellow. After I mowed few have come back. A single packet only makes a gallon. If you have a significant problem, buy a couple of packages. This product doesn't kill your grass.

    4 of 5 stars  Trying to KILL nutsedge
    By Harvey in Evansville, In 47725 on 08/18/2011

    The product seems to work just fine. BUT I will not know how well it worked, until next year. If the nutsedge comes up again in the same areas that will not be good. Looks good for now. Harvey

    By Wayne in Port Clinton, Ohio on 08/21/2011

    Got tired of hand picking Yellow Nutsedge out of my lawn. This stuff worked great, even after it rained after application when not expected. Within 3 days Nutsedge starting dying off and has not returned as of yet. Very reasonable price to pay for a product that worked this well.

    If you have NUTT Grass, it will remove it well without damaging the Bermuda Grass.

    By Tom in Just Retired on 08/18/2011

    I used the Halosulfuron to rid my yellow nutsedge which showed up in my lawn this year. It looks as though it worked but did take time to see results. I recommend this product if you have this problem. I did not know what the other ingredient was but called my friend Hal who owns a farm and he told me to add 5 tablespoons of detergent which is the same thing and it worked. He has been farming for longer than I am old, so he knows all about these kinds of issues. TOMCAT

  • 4 of 5 stars  The Scourge of Nutsedge
    By Rick in Mentor on the Lake, Ohio on 08/16/2011
    Verified Purchase

    Finally, something that is actually effective in my seemingly unending battle to control the nutsedge in my yard. I have tried a number of products in the past few years, but nothing has produced the results I've gotten with this product. The only reason I don't give it the highest rating is that I'm waitng to see it's long term effects. My yard looks great as this product only attacks the nutsedge without damaging the rest of the lawn. I'll definitely use it again next year if the nutsedge reappears.

  • 5 of 5 stars  Halosulfuron comments
    By Ron in Dade City, FL on 08/16/2011
    Verified Purchase

    The product appears to be working as advertised, but I have a question regarding it's application. The five stars are tentative since the product has only been applied for two weeks but it sure has killed the above ground part of the plant. Not sure about the underground part yet. The label does not mention how long you have to leave the visible part of the treated sedge alone before the product has had a chance to spread throughout all of the underground part of the plant. This is not an issue if the sedge is in the lawn, but it is if you want to kill the sedge that has invaded an area of shrubbery, but also want to get rid of the visual part ASAP. If I wait a day and then pull the sedge, along with whatever underground part comes along, will I be diminishing the effectiveness of the product?

  • 5 of 5 stars  DO NOT PULL NUTSEDGE GRASS
    By in Excelsior Springs, MO on 07/28/2013

    I talked to two different people at nurseries and they both said that pulling nutsedge causes the root structure to multiply which increases the problem. I bought Halosulfuron.

QCan Halosulfuron Pro be used to kill nut grass and not kill my grass?

AYes, Halosulfuron Pro is a selective herbicide meaning it will kill your nutsedge in your grass, but not harm your grass.  You should read the product label to ensure that it is compatible with the type of grass that you have.  It is also important that you apply the right amount of product so you do not harm your grass that you do not want to kill.

QWill Halosulfuron kill the current and future nut grass under my pool liner?

AThe product you are currently asking about has been replaced by the manufacturer with a product called Pro-Sedge. It is the same active ingredient just a different name and look. The Pro-Sedge is a post emergent herbicide for Yellow and Purple Nutsedge as well as a few other broadleaf weeds. This will only kill the current grass that is there but it will not prevent new nutsedge from coming up. There is currently no pre emergent product on the market for nutsedge.

QCan Halosulfuron be used safely in and around vegetable gardens, and fruit trees? Is there any toxicity to vegetables & fruit trees?


Halosulfuron Pro Herbicide is meant more for nutsedge control in turf grass and it cannot be used near a vegetable garden or anything edible.
