  • Residual activity that lasts right up to canopy closure
  • Wide application window from pre-emergence to the 8-leaf stage in glyphosate-tolerant corn
  • Combining Group 27 and Group 15 chemistries, Armezon PRO offers multiple modes of action and is tank mixed with atrazine or atrazine and glyphosate
  • Armezon PRO can also be applied in tank mix with Marksman® herbicide and Roundup WeatherMAX® with Transorb® 2 Technology Liquid Herbicide1

Benefits of Armezon PRO

Armezon PRO provides fast-acting control of broadleaf weeds and grasses, with residual activity that lasts right up to canopy closure. With Group 27 and Group 15 chemistries, it offers multiple modes of action for tank mixing with atrazine2(for conventional corn) or glyphosate plus atrazine2 (for GT corn). Flexible staging is included with a wide application window between the spike and 8-leaf stage in GT corn.

2Marksman herbicide as a source of atrazine is an optional tank-mix partner*, providing an additional mode of action for enhanced control of glyphosate-resistant weeds. For a tank-mix of Armezon PRO plus Marksman herbicide plus Roundup WeatherMax with Transorb 2 Technology Liquid Herbicide, see “When to apply" and “How much to apply” for further details

Application Tips

Prior to application, store Armezon PRO in a cool, dry place and protect from freezing.

For best performance spray weeds before they have reached the maximum leaf stage recommended on the label.

Temperature and moisture conditions for active plant growth are important for best results.

Rainfastness – Limited by glyphosate formulation.

Pre-harvest interval

80 days after application.

45 days after application for grazing or feeding treated corn forage, silage, fodder or grain to livestock

Mixing Instructions

  1. Fill clean spray tank half full with clean water and start agitation.
  2. If using dry tank mix partner, add correct amount to the tank and agitate.
  3. If using liquid or solution herbicide tank mix partner add correct amount.
  4. Add the correct amount of Armezon PRO while continuing agitation.
  5. Glyphosate: If adding a glyphosate formulation with full load of surfactant, add the correct amount to the tank after the addition of Armezon PRO. If adding a glyphosate formulation with low load of surfactant, add the correct amount prior to adding Armezon PRO into tank.
  6. Add either Merge adjuvant to the spray tank or Assist followed by liquid fertilizer (UAN 28%), with the exception of glyphosate tank-mixes.
  7. While agitating, fill the remainder of the tank with water up to the proper level.
