• Controls yellow and purple nutsedge and certain tough broadleaf weeds like horsetail.
  • Also suppresses green kyllinga.
  • Low use rate (1 1/3 oz/Acre or less) or .9 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

  • 1.33oz Container: Using included spoon, which measures .9 grams, scoop one spoonful and pour into 1 gallon of water.
  • Mix the solution thoroughly. The 0.9 grams will cover 1,000 sq ft
  • Add 2 teaspoons of a nonionic surfactant and shake gently until mixed well. See below for more information on non-ionic surfactants.
  • 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.

Non-Ionic Surfactants

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 products to “sheet” or spread across a surface. 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.

For best results, add a surfactant that is specifically made for horticultural purposes and labeled for use with an herbicide. If a nonionic surfactant is not available certain dishwashing detergents that contain high amounts of a nonionic surfactant may be helpful. Check the label of a dish soap to see if it contains a nonionic (not anionic) surfactant. The soap may contain both or just the anionic surfactant. If the label says it contains a nonionic surfactant, that is preferred. Dish soaps that are concentrated and are effective in grease dispersion often contain nonionic surfactants. Add the detergent last and mix by gently swirling together. See the”How to Use” page for more information.

Some commonly used nonionic surfactants are Hi-Yield® Spreader Sticker, No Foam A® , Latron B- 1956®, and X-77®.
