Armezon is the new post-emergent herbicide with outstanding crop tolerance for seed, sweet and field corn.

  • Armezon tank-mixed with glyphosate on glyphosate tolerant corn provides increased broadleaf weed control and excellent burn-down of annual grasses, without relying on a Group 2 herbicide.
  • It offers a flexible application window from the 1 leaf to 7 leaf stage of corn.

  • Clean up specialist in field, seed and sweet corn, offering knockdown of key weeds, with unparalleled crop safety.

Flat fan or similar spray nozzles should be used for application.
Denser weed infestation requires the use of higher water volumes.
Recommended pressure is 275 kPa.

Tank Mixes

For tank mixes with herbicides OTHER THAN glyphosate:

  1. Fill sprayer ½ full with clean water and agitate.
  2. Add dry tank mix partners into the spray tank and agitate.
  3. Add Armezon herbicide and thoroughly mix.
  4. After the Armezon herbicide has visibly dispersed, add any liquid herbicide tank mix partners.
  5. Add either Merge adjuvant to the spray tank or Assist followed by liquid fertilizer (28% UAN).
  6. While agitating, fill the remainder of the tank with water up to the proper level.

For tank mixes of Armezon with glyphosate or with glyphosate plus atrazine, DO NOT add Merge or Assist followed by liquid fertilizer.


NOTE: If using Armezon in tank mixtures, always refer to the tank mix partner's product label for any additional re-cropping restrictions.
