Take a Flexible Approach to Weed Control

Weed control in wheat can vary dramatically due to environmental conditions, weed species and growth stages. Develop a weed management program with maximum application flexibility to tackle weeds in winter wheat.

Fall herbicide applications may not control late fall- or early spring-germinating winter or summer annual weeds. An early spring treatment after summer annuals emerge may be more effective.

For broadleaf weed control, Quelex® herbicide fits as the core of a weed management program in wheat. It provides advanced broad-spectrum control of troublesome species, such as marestail, henbit and mustards.

As the crop comes out of dormancy, apply herbicide with a top-dress fertilizer for minimal wheat stand impact.

“Weed-and-feed applications give the wheat a boost and provide weed control at the same time,” says Chad Cummings, field scientist, Corteva Agriscience. “Quelex herbicide is tank-mix-compatible with other herbicides, fungicides and insecticides and allows growers to mix in a full 100% UAN solution.”

Weather and level of weed infestation may delay herbicide applications. Later in the spring when wheat begins to green up, apply herbicides as early as possible for proper spray coverage, especially on winter annual weeds.

Winter annuals will become a component of harvest if uncontrolled. With a wide application window, Quelex herbicide can be applied to winter wheat from the two-leaf to flag leaf emergence stage for broadleaf weed control.
