Corteva Agriscience Reveals New Corn Herbicide Planned For 2022


Today, Corteva Agriscience revealed a new corn herbicide planned for the 2022 season. Resicore XL herbicide is a preplant, pre- and postemergence corn herbicide with three powerful modes of action. The new product will offer increased crop safety and application flexibility on corn greater than 11-inches tall to control more than 75 of the toughest broadleaf and grass weeds. Resicore XL is a flexible solution designed to fit nearly any corn farmer’s weed control program. The product will be available upon obtaining U.S. Environmental Protection Agency (EPA) registration.

“We’re excited to continue to bring innovative products to the marketplace by announcing our newest corn herbicide today,” said Brandon Walter, U.S. product manager, Corn Herbicides, Corteva Agriscience. “Resicore XL is the next chapter in that innovation story – a game-changing corn herbicide that combines the weed control farmers trust with next-level application flexibility and crop safety.”

Over the last 20 years, Corteva launched nine cutting edge corn herbicide formulations to fit the way farmers farm, as their needs changed. SureStart II herbicide, a flexible pre-emergence that allows farmers to start clean, and Resicore herbicide, a powerful solution with extended residual control, were two of those innovative solutions. In fact, according to Kynetec Market Research, Resicore was the most widely used residual corn herbicide in the U.S. in 2019 and 2020.

Resicore XL will build on the success and proven weed control corn farmers have come to expect from its predecessor Resicore. The new solution will elevate the farmer experience with enhanced features and benefits, such as, increased crop safety, a wider application window and greater tank-mix compatibility.

Resicore XL will fit a wide variety of weed control and agronomic programs, because it can be applied preplant, pre- or postemergence on corn greater than 11-inches tall. Farmers will also have the option to customize their application rates. This flexible solution will give farmers power over weeds with three proven modes of action to control more than 75 of the toughest broadleaves and grasses, including Palmer amaranth, waterhemp, marestail and giant ragweed.

“Farmers are looking for innovative solutions that fit their farming operations. Resicore XL herbicide offers increased crop safety and the widest application window of any Corteva Agriscience corn herbicide along with the proven, powerful weed control they’ve come to expect from our products,” Walter said. “Resicore XL will make an excellent addition to almost any weed control program as a preplant, pre- or postemergence option to help manage herbicide resistance and optimize yield potential.”

Resicore XL is anticipated for EPA registration in 2022. Following registration, the solution will be available for sale. To learn more about Resicore XL, visit on, or reach out to your local Corteva Agriscience representative.
