How it Works

  • Centurion is a systemic herbicide which is translocated from the treated foliage to the growing parts of the leaves, shoots and roots.
  • Applied at 154 ml/ac, Centurion herbicide offers season-long control of quackgrass, without the need for a fall application of glyphosate.
  • Applied at 77 ml/ac suppresses quackgrass and allows the crop to establish itself without impacting yield. Combined with a fall application of glyphosate, quackgrass can be effectively burned down for the next season.
  • Registered for both aerial and ground application.

Application Tips

For dense crop canopies, use a minimum water volume of 12 gal/ac to maximize coverage.
