Gowan Company, LLC


 Sedgehammer+ Turf Herbicide 0.5 Oz.

  • Controls yellow and purple nutsedge and certain tough broadleaf weeds like horsetail.
  • Non Ionic Surfactant no longer needed.
  • Also suppresses green kyllinga.
  • Low use rate 13.5 grams per 1000 square feet.
  • Controls nutsedge by moving through the plant and affecting the underground growing points (rhizomes and tubers).
  • It controls nutsedge after emergence in cool and warm season turfgrass (including St. Augustinegrass, Bermudagrass, Kentucky bluegrass, tall and fine fescue, and perennial ryegrass)
  • Considered as one of the more “gentle to turfgrass” products.
  • Pets and people can return to treated area once spray dries.

How to Use SedgeHammer+

  • Open packet and pour into 1 gallon of water. 
  • Mix the solution thoroughly. One packet will cover 1,000 sq ft.
  • DO NOT add any non-ionic surfactant - it is already included in the packet for easy mixing.
  • 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 within 24 hours of initiating mix.

    Just as advertised

    It makes me feel good as a customer when I get a fair deal on purchases (especially the shipping charges) Your price for the product and the cost of shipping were both very fair and reasonable.

    came quick and works!

    I ordered SedgeHammer + and it came quickly and does the job on the nutsedge. I saved the card so that I can order more next spring for the inevitable nutsedge that pop up each year no matter what.

    Daniel use of sledge hammer

    This is the best product for killing net sedge. After one application the net sedge turned yellow after about 8 days and died after 2 weeks.

    Takes time but works!

    this works wonders, it takes some time, probably 3 to 4 weeks for you to see a result, then Nutsedge will turn yellow, and slowly die, the actual grass is healthy with no damage. If you want to see immediate results, this is not the product for you, but it definitely works. I will be doing a second application in about 2 to 3 weeks because my turf had a lot of Nutsedge in it
