Controlling Weeds in Corn Long Term
Something went wrong. Please try again later...
As a business that works closely in the field with your customers, you know that tough broadleaf and grass weeds can intensify year after year, requiring more inputs and reducing corn yield.
“A program approach is going to be key from a weed management standpoint to prolong the longevity of all the chemistries we are using to control weeds today,” says Ron Geis, Corteva Agriscience Market Development Specialist. “A program approach uses preemergence herbicides in conjunction with our postemergence herbicides for effective, long-lasting weed control and higher yield potential.”
Program Approach Weed Control
Products that fit the way you farm
Long-term, effective weed control requires more than a one-size-fits-all approach. That’s why Corteva Agriscience provides customized corn herbicide programs to address your customers’ unique weed challenges.
“An effective corn weed control program could include Resicore® REV herbicide, followed by Kyro™ herbicide stemergence,” Geis says. “These solutions offer effective modes of action and extended residual activity against the toughest broadleaf and grass weeds in cornfields.”
Resicore REV is the foundation for corn farmers to build a proven, premier weed control program. Resicore REV herbicide combines three proven active ingredients – encapsulated acetochlor, clopyralid and mesotrione – to provide farmers the season’s strongest start. With three modes of action, Resicore REV herbicide gives farmers outstanding control of 75 tough broadleaf weeds and grasses.
Farmers have increased application choices with Resicore REV herbicide. It can be applied preplant, preemergence or postemergence on corn up to 24 inches tall, allowing it to complement a variety of agronomic programs. Resicore REV herbicide helps farmers achieve maximum yield potential with up to eight weeks of residual control and reduced crop response.
Choosing Kyro herbicide as a postemergence option ensures excellent crop safety for higher yield potential and provides both postemergence and residual control of persistent weeds for long-term weed control. Kyro herbicide offers flexible application timing on up to 24-inch corn and the ability to tailor weed control programs to fit your customers’ unique corn acres.
The Corteva Agriscience corn herbicide portfolio offers a variety of complementary herbicide options that seamlessly integrate into corn weed management programs for long-lasting weed control, resistance management and optimized yield potential.
