How it Works

  • Armezon herbicide is a Group 27, post-emergent herbicide that is quickly absorbed by leaves, roots, and shoots to quickly control target weeds.
  • Corn growers using Armezon tank-mixed with glyphosate get the benefits of multiple modes of action for excellent control of annual grasses and broadleaf weeds.
  • Clean up specialist in field, seed and sweet corn, offering knockdown of key weeds, with unparalleled crop safety.

Tank mixes
Armezon can be used as a standalone herbicide (for application in field corn only) or tank mixed with glyphosate and/or atrazine.

See label for full details on tank mixes.

Application Tips

  • Follow the glyphosate manufacturer’s recommendation for rainfast guidelines.
  • Denser weed infestation requires the use of higher water volumes.
