Primextra II Magnum

Primextra® II Magnum® keeps fields clean so emerging corn can perform to its full yield potential. Tank mix with Callisto® for a one-pass Foundation Acre® treatment, or make an application of Primextra II Magnum followed by Callisto plus glyphosate* or Callisto GT* for a two-pass approach.

Groups: 5, 15


  • Consistent residual weed control for up to 14 weeks after application.
  • Unsurpassed crop safety.
  • Safe for your crop rotation: Primextra II Magnum binds to the soil and stays there to fight weeds throughout the season, but it is broken down in the soil long before you’re ready to re-plant.
