Help Customers Build a Successful Soybean Herbicide Program

As a retailer, you know the value of a program approach to weed control. But it can sometimes be difficult to explain the value of each herbicide application to your customers.
“When part of the program approach is missed, the grower often has to play catch-up and battle weeds with an increased amount of chemistry, which can affect crop yield,” says Tony Goede, Enlist® field specialist, Corteva Agriscience.
We broke down the benefits of each application so you can help your customers dial in their soybean weed control program approach.
Tillage and/or Burndown Applications
“Starting with tillage or a burndown application helps prepare the field for planting,” Goede says. “Creating a desirable seedbed to plant into promotes better germination and plant health to start the growing season off strong.”
Product recommendations
- Enlist® herbicides are the perfect pairing with Enlist E3® soybeans from burndown through the R1 stage of development.
- Elevore® herbicide provides superior control of broadleaf weeds, including ALS- or glyphosate-resistant species.
Preemergence Applications
Any weed in the field after planting will compete with the crop for important soil nutrients. That’s why it’s important to use quality preemergence herbicides that include a residual.
“A preemergence application with a residual herbicide will protect the crop from weed competition and control weeds with long emergence periods,” Goede says.
Product recommendations
- Sonic® herbicide is a convenient tank-mix partner that delivers long-lasting residual control when applied before soybean emergence.
- Trivence® herbicide uses three modes of action to provide reliable control of the most challenging broadleaf weeds in soybeans, including Palmer amaranth, marestail, waterhemp, giant ragweed, morningglory and lambsquarters.
Postemergence Applications
Proper application timing will depend on diligent scouting and targeting small weeds. Postemergence applications often occur 21 to 28 days after planting.
“The Enlist One herbicide label requires weeds to be less than 6 inches; however, applying a postemergence application when weeds are 2 to 4 inches tall will bring you the best results,” Goede says.
He recommends keeping an eye on fields after the first postemergence application, as some weeds continue to germinate well into the growing season. If there are more weeds present, a second postemergence application may be necessary.
“Choosing chemistries that can be sprayed on the crop at this time is important. Growth stage of the crop as well as calendar dates will affect your herbicide options,” Goede says.
Product recommendations
- EverpreX® herbicide provides extended residual control of ALS-, PPO- and glyphosate-resistant weeds in an easy-to-use formulation.
- Enlist One® and Liberty® herbicides give farmers the best postemergence control available for tough and resistant weeds on Enlist E3® soybean acres.
- Coming soon: Enversa™ herbicide will come in a proprietary, encapsulated acetochlor (Group 15) formulation for residual control of challenging weeds. The encapsulated acetochlor will complement tank-mix partners by allowing Enversa to drive to the soil and provide a residual barrier against weeds that haven’t emerged. Enversa will be the tank-mix partner of choice for Enlist One herbicide.
“Using residuals in preemergence applications and in conjunction with Enlist herbicides postemergence brings the best opportunity for effective season-long weed control,” Goede says.
Remember Multiple Modes of Action
Using multiple modes of action not only helps to target different types of weeds but also helps to battle tough-to-control weeds, including waterhemp, Palmer amaranth and giant ragweed. Allowing multiple chemistries to tackle troublesome weeds improves control and will help keep active ingredients viable for years to come.
“Having the right chemistries is critical to keeping fields clean,” Goede concludes. “Make sure you have the best lineup possible for your geography and that you have the correct brand and anticipated volumes for each crop and customer.”
