Acuron GT Post-Emergence-Plus-Residual Corn Herbicide Now Registered

March 8, 2021

Weeds steal sunlight, moisture and nutrients from the growing corn crop, so the better you can control weeds, the less yield-robbing competition you’ll have.

To better manage tough weeds, we are eager to announce that Acuron® GT has been registered by the U.S. Environmental Protection Agency for post-emergence use in glyphosate-tolerant corn and will be available in 2021 for trial use, subject to state approvals.

Acuron GT is the ultimate post-emergence herbicide in corn that delivers enhanced control of yield-robbing weeds and longer-lasting residual compared to any other product because it is the first and only glyphosate premix that contains the unique ingredient bicyclopyrone (BIR).

In field trials, Acuron GT has averaged greater than 90% post-emergence control on all weed categories, including:

  • Small- and large-seeded broadleaves.
  • Giant ragweed.
  • Morningglory.
  • Cocklebur.
  • Pigweed species such as Palmer amaranth and waterhemp.1

The powerful combination of 4 active ingredients and 3 sites of action in Acuron GT also helps manage difficult weeds longer into the season, which helps fully protect yield potential and minimize the weed seed bank for next year’s crop.

Compared to Halex GT, field trials show Acuron GT provided an 8% increase in residual control of annual grass and small-seeded broadleaf weeds and a 14% increase in residual control of Palmer amaranth when evaluated 42 to 56 days after treatment.2 Acuron GT may help achieve almost 90% control of weeds 6 to 8 weeks after post-emergence application due to the addition of BIR and its residual power.2

Acuron GT delivers enhanced post-emergence control of yield-robbing weeds and longer-lasting residual that enable it to deliver more bushels per acre than any other post-emergence-plus-residual corn herbicide, including Halex GT. Across 16 head-to-head replicated trials in glyphosate-tolerant corn, Acuron GT outyielded other post-emergence-plus-residual herbicides3.

For optimum yield protection, we recommend using Acuron GT early post-emergence, before weeds reach 4” in height, in a planned 2-pass program following preemergence applications of Lumax® EZ, Lexar® EZ, Bicep II Magnum®, Bicep Lite II Magnum® or Dual II Magnum® herbicides.

When you start with agronomics and a profitability goal in mind, you can better assess what practices and products will get you there. Using a residual preemergence herbicide is critical in a program with Acuron GT to deliver sound weed resistance management strategies, and to help protect yield and profit potential.
