Higher yielding corn starts with fast weed control

When it comes to weed control, how quickly herbicides take action can mean the difference between low and high yields.

That’s because weeds threaten your yield potential and cause management headaches as soon as they emerge. The longer those weeds are there, the more damage they do.

Early-season weeds steal vital nutrients like nitrogen and water that are needed for proper corn growth. Research shows just how big a bite these weeds can take. Consider that 1-inch to 2-inch weeds consume over 9 pounds of nitrogen per acre, and in 3 days, 3-inch weeds can remove 1 inch of water from the soil.1 Even non-competitive early-season interactions between weeds and corn can significantly alter corn growth, development and yield potential.

Without early-season intervention, troublesome weeds can quickly outgrow the 4” threshold recommended for best treatment results, so time is always of the essence, making fast knockdown key.

Fast-acting control

Herbicide resistant weeds continue to be a problem for growers season after season. Choosing the right weed management program is vital to eliminating the threat of weeds quickly and maximizing yield potential.

Planning ahead for 2025, one product we recommend for growers using glyphosate-tolerant systems is Acuron® GT herbicide, which outperforms and outyields any other post-emergence-plus-residual corn herbicide. Acuron GT, a post-emergence-plus-residual corn herbicide, provides faster knockdown and enhanced control of 90+ yield-robbing grass and broadleaf weeds, including Palmer amaranth, waterhemp, giant ragweed, morningglory, marestail, giant foxtail, kochia, cocklebur and burcucumber.

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

A solid one-two punch of preemergence and post-emergence herbicide applications is a sound agronomic strategy and helps ensure clean, weed-free fields from start to finish.

Better yield is the better deal

When you start with agronomics and your end profitability goal in mind, you can better assess what practices and products will get you there. Before you commit to a season-long “deal” that may limit your choices, do some math and see how everything pencils out — because better yield with Acuron GT is the better deal.
