A preemergence herbicide can sometimes make or break your soybean weed control program. For example, if you don’t have the right modes of action to take on the weeds in your fields, it doesn’t matter how many modes of action you apply. And if you have all the right modes of action but no residual activity, you might have weeds that are too far gone by the time you can apply your postemergence herbicide.
Choosing just the right solution for your operation is key. A powerful combination of the right modes of action and long-lasting residual activity can set you up for the best possible yield potential.
Corteva Agriscience brought Kyber™ herbicide to the market in time for the 2021 growing season and brought with it three effective modes of action in one convenient premix with extended residual control. It’s a powerful preemergence solution for taking on some of the most difficult, herbicide-resistant weeds.
“Kyber herbicide gives farmers a head-start on their soybean crops with clean fields, leading to maximum yield potential and the potential for more money in their pockets,” says Aaron Smith, U.S. product manager, soybean herbicides, Corteva Agriscience. “Kyber is particularly strong against resistant weeds like waterhemp and Palmer amaranth.”
One of the modes of action in Kyber is a Group 15 herbicide. Group 15 herbicides are also known as long-chain fatty acid inhibitors. They’re important, because weeds like waterhemp and Palmer amaranth continue to develop resistance to modes of action such as PPO inhibitors and ALS inhibitors. A chemistry with a Group 15 herbicide can help control those weeds and manage resistance.
“At Corteva, we’re always thinking of ways to make our customers’ jobs easier. We know that farmers continue to struggle with herbicide resistance,” Smith says. “Farmers have also been asking for soybean solutions that include a mode of action from Group 15. Kyber has that Group 15 active ingredient.”
In addition to these three effective modes of action, farmers have asked for long-lasting residual activity to keep their soybeans clean until it’s time for a postemergence herbicide application. Kyber has that, too.
“The residual activity in Kyber herbicide lasts four to six weeks. In the right conditions, it can last even longer than six weeks,” Smith says. “We spoke to an Iowa retailer specifically who said his customers saw residual activity past the six-week mark.”
As stated previously, a preemergence herbicide can make or break your soybean weed control, but it should by no means be the only solution you use each season. Smith recommends applying a burndown in fall and/or early spring with a product such as Elevore® herbicide and following up your preemergence with a timely postemergence application.
Here’s a look at three of the postemergence solutions Corteva offers:
Don’t let weeds compete with your soybeans this season. Set your beans up for clean fields and optimum yield potential with a powerful preemergence as part of a weed control program. Talk with your local retailer about the solutions that will work best on your farm.
