An untreated check plot at our Pontiac, IL, Grow More^TM Experience site shows heavy weed pressure. Photo taken July 2020.

Our 2020 Grow More Experience site in Pontiac, IL, featured a bare-ground trial comparing the performance of Acuron® herbicide vs. Armezon® PRO herbicide. The trial also included an untreated check, where we see that weed pressure was very high in the area.

Bare-ground trials give the clearest possible picture of product performance. Unlike in-crop trials where corn will eventually canopy and shade out weeds, bare-ground trials indicate what level of weed management a product offers when most other factors have been removed.

In the video below, the Armezon PRO plot looks relatively clean in June, but by July several weeds have escaped. In contrast, the Acuron plot is almost completely clear of weeds, and there are no significant changes in the plot from June to July, indicating the longer-lasting residual Acuron delivers.

Why choose Acuron?

• Acuron manages a broader spectrum of weeds than Armezon PRO. Armezon PRO isn’t labeled for control of several key Midwestern weeds, including giant ragweed, cocklebur and lambsquarters.
• Acuron offers the longest-lasting residual on the market, whereas Armezon PRO has a shorter window of residual control. Because of its shorter length of residual, Armezon PRO often isn’t applied until weeds have emerged, putting growers at greater risk of increasing their weed seed bank and suffering yield loss.
• Acuron contains 4 active ingredients and 3 sites of action, while Armezon PRO contains 2 active ingredients and 2 sites of action. This makes Acuron a stronger option for herbicide resistance management.
  • Bicyclopyrone is a unique component that is one of the 4 active ingredients in Acuron. It works together with mesotrione to deliver more powerful, longer-lasting and consistent weed management than competitors. This superior weed management prevents weeds from stealing nutrients, water and sunlight from the crop and leads to higher yield potential, with Acuron outyielding other herbicide programs by 5-15 bu/A.* Calculate what those extra bushels could mean for your revenue potential.

As the video from our Pontiac, IL, site shows, Acuron holds strong against tough weeds, while growers who rely on Armezon PRO may be left with a mess later in the season.
