Step by Step Instructions

How to Use

  • First, determine the type of sprayer you're using. Then, refer to "Mixing Instructions" to look up the proper amount of product to add to the sprayer based on the type of sprayer you're using and the type of grass you're spraying.
  • Next, add product to a Tank Sprayer or Ortho® Dial-N-Spray® along with water if indicated. Finally, turn the dial on the Dial-N-Spray to the correct setting (if using). Then, apply at the correct time and avoid spraying as a fine mist, which can cause injury to other plants.
  • The maximum application rate is 6.0 fl. oz. of product per 1,000 sq ft per application and no more than 2 treatments per year.
  • Remember: A little goes a long way with this herbicide. More is not better, as over-application or rates above those recommended on this label can cause grass injury!
