Grant Harms, Market Development Specialist with Corteva Agriscience, shares insights from the Iowa State University Northwest Research Farm on how different residual herbicides perform against late season waterhemp.

He highlights Kyber® PRO, which combines fast-acting and long-lasting ingredients for reliable weed control, Sonic®, which delivers strong burndown and residual activity on broadleaf weeds, and Sonic® Boom, a new co-crystal formulation designed to keep chemistry in the upper soil profile for extended control and crop safety. By layering residuals, farmers can strengthen their residual program and stay ahead of waterhemp pressure throughout the season.
