Fewer Weeds Equals More Bushels and More ROI

October 14, 2020

When not competing with weeds for sunlight, water or nutrients like nitrogen, corn can better reach its full yield potential. A good herbicide will control tough weeds, but a truly powerful herbicide will have all of these benefits:

In this series, we’ll explore all of these benefits more in-depth, but in the copy below, we’re focusing on how effective weed control can impact your bottom line.

Clean, Weed-Free Fields Mean More Bushels at Harvest

One of the biggest corn yield-robbers you face each year is early-season weed pressure. Weeds can steal vital nutrients needed for growth and grain fill. Per the 3:3:1 rule, in 3 days, 3” weeds can remove 1” of water from the soil.1

Weeds present at corn emergence also redirect the sun’s rays and fundamentally alter corn growth. These changes negatively impact corn yield and revenue potential, and can’t be overcome with post-emergence weed control alone.2 If a field is taken over by weeds it hurts your bottom line that season, and the increase in the weed seed bank can create problems for years to come.

Bill Johnson, Ph.D., professor of weed science at Purdue University, says it only takes 1 year of poor weed control to create a decade of headaches from resistant weeds, and that the worst thing you can do is get complacent and think, “if it’s not broke, don’t fix it.” Staying on top of weed management and herbicide resistance is all about making those subtle adjustments before you make drastic changes.

To prevent a decade of weed management difficulties, plan on a corn herbicide program with powerful weed control.

Sarah Lancaster, Ph.D., assistant professor and extension specialist at Kansas State University, says applying multiple effective sites of action at full rates is critical to slowing the development of herbicide resistance and having high levels of weed control.

Acuron® corn herbicide combines 4 active ingredients, including the unique component bicyclopyrone, and 3 effective sites of action (Groups 5, 15 and 27) to provide more consistent and powerful control of tough, yield-robbing weeds that other products miss. Less weed competition translates into more nutrients, sunlight and water available for the growing corn crop, which leads to more bushels and extra revenue potential.

The unique combination of powerful weed control, longest-lasting residual and proven crop safety mean only Acuron can unlock corn’s full yield potential. When used in a preemergence application at full label rates, Acuron can help you find 5-15 more bushels an acre than with any other corn herbicide.*
