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.
