Shake Up Your Corn Herbicide Program

November 5, 2020

It can be easy to fall into the same-old, same-old routine, but when it comes to weed resistance, that is a recipe for disaster. Resistant weeds require you to switch things up by diversifying your chemistries to preserve their long-term efficacy and best manage weeds. It’s more than just rotating crops and herbicides season to season.

Your corn herbicide program should contain the following essentials to protect your yield potential from resistant weeds:

In this series, we’ll explore all of these benefits more in-depth, but in this post, we’re focusing on the role effective sites of action (SOAs) play in your weed control plan, and which unique active ingredient (AI) your corn herbicide might be missing.

Get Ahead of Resistant Weeds with Multiple Effective SOAs

Corn herbicides are only as good as their AIs, and not all products provide the same level of value. With current corn commodity prices, you need the best tools in your toolkit, and your corn herbicide has to deliver a strong return on investment.

Cheaper generic options may lack thorough testing and company backing, and can be made up of older technologies and AIs that weeds may already be resistant to. Many herbicides are premixed with multiple SOAs, but not all are effective on the specific weeds in each field.

Charlie Cahoon, , an N.C. State University Extension weed specialist, says weed resistance is a numbers game and that it’s paramount to apply multiple effective SOAs. The key word is effective, meaning 2 SOAs that both work against the same weed. If you applied 2 SOAs, and one of them doesn’t work on that weed, it really doesn’t put you in a better situation from a resistance standpoint.

Acuron® corn herbicide contains 4 active ingredients, including the unique component bicyclopyrone, and 3 effective sites of action for the longest-lasting residual weed control with built-in resistance management.

Bicyclopyrone is the Syngenta-exclusive AI that sets Acuron apart from other corn herbicides. More than 1,000 trials show bicyclopyrone helps Acuron provide built-in burndown, greater consistency, powerful weed control and longest-lasting residual.

Bicyclopyrone complements the AI mesotrione, which is another HPPD-inhibitor. They work together to deliver even more powerful, broad-spectrum weed control. Combined with atrazine and S-metolachlor, a Group 15 herbicide, bicyclopyrone and mesotrione enable Acuron to control weeds better and more consistently than any other corn herbicide on the market.

This enables Acuron to deliver a higher level of weed control more often, resulting in fewer weed escapes and fewer resprays – saving time and money in-season. And when applied preemergence and at the full labeled rate, replicated Syngenta and university trials show Acuron outyields competitors by 5-15 bushels an acre because it controls tough weeds other products miss,* meaning corn can reach its full yield potential at harvest.
