Weeds continue to develop resistance to herbicides. Farmers have been asking for new solutions. Steve Snyder, Enlist® field specialist, says the Enlist® weed control system is giving farmers more ways to overcome their weed issues.
“Farmers can use herbicides that feature multiple sites of action to control tough and resistant weeds,” Snyder says. “Enlist E3 soybeans are tolerant to three postemergence herbicides that feature different sites of action: 2,4-D choline, glyphosate and glufosinate – the active ingredient in Liberty herbicide.”
Snyder suggests adopting a program approach that first recognizes the weed challenges in a given field. The farmer can choose herbicide options that are effective against the weed species in that field.
“Try to start clean and stay clean,” he says. “Use a burndown or tillage for early-season weed control. Then apply preemergence herbicides, making sure to include a product or products with residual activity to keep weeds at bay as long as possible.”
Next choose an effective postemergence program.
“The Enlist weed control system allows farmers to employ multiple sites of action postemergence on Enlist crops,” Snyder says. “This not only helps control tough and resistant weeds during the growing season but also helps retard the development of resistant weeds.”
Farmers who plant Enlist E3 soybeans can apply Enlist Duo® and Enlist One® herbicides postemergence to control difficult, resistant weeds. Inherently low volatility 2,4-D choline is the key ingredient in Enlist Duo and Enlist One®herbicides.
“Growers who plant Enlist E3 soybeans can apply Enlist Duo, a convenient blend of 2,4-D choline and glyphosate,” Snyder says. “Or they can tank-mix Enlist One, a straight-goods 2,4-D choline, with qualified products, including Liberty herbicide. Both options provide multiple levels of protection against tough weeds. Users gain convenience and flexibility with Enlist herbicide options.”
The industry-leading triple herbicide tolerance trait gives farmers more choices and flexibility. This system provides a vital new option for controlling tough weeds in soybeans while helping address herbicide resistance.
“The first call should be to your seed dealer,” Snyder says. “Find out what E3 varieties they have available.”
In 2020, Enlist E3 soybeans will be available from all Corteva Agriscience seed brands. In addition, Corteva has been working with other seed providers. More than 100 companies are licensing the Enlist technology and bringing Enlist E3 soybeans to customers. This means, going forward, there will be more options for farmers to get the weed control solutions they need.
