Corteva Agriscience unveils new corn herbicide slated for 2022

This premix of Groups 4, 15, and 27 designed for preplant, preemergence, and postemergence use.

Corn farmers are slated to have a new corn herbicide premix for 2022. Corteva Agriscience’s Resicore XL herbicide contains three herbicide sites of action: acetochlor (Group 15), mesotrione (Group 27), and clopyralid (Group 4).

It contains the same herbicide sites of action as Resicore, which was the most widely used residual corn herbicide in the U.S. in 2019 and 2020, according to Kynetec Market Research. Resicore XL builds upon Resicore herbicide by featuring increased crop safety and application flexibility on corn greater than 11 inches tall to control more than 75 broadleaf and grass weeds, say Corteva Agriscience officials. 

“This includes some of the most troublesome weeds like Palmer amaranth, waterhemp, marestial, and giant ragweed,” says Brandon Walter, U.S. product manager, corn herbicides, Corteva Agriscience. “Resicore XL is a premix corn herbicide that can be applied preplant, preemergence, and postemergence on corn and give farmers the type of flexibility to fit any agronomic program across the United States,” says Walter. 

The crop safety of Resicore XL herbicide is enhanced by encapsulated acetochlor, says Walter. Another feature of Resicore XL herbicide is greater tank mix compatibility, such as with products like atrazine and glyphosate. 

“Resicore XL will offer farmers greater tank mix compatibility with key micronutrients and other products, such as UAN and ammonium thiosulfate (ATS),” adds Walter.

Resicore XL is slated to debut in 2022, pending regulatory approval by the U.S. Environmental Protection Agency (EPA).
