“From the Field” Findings


―Wet weather delayed corn planting beyond the suggested

7-day window. Corn remains clean!‖

—Curtis Thompson, Kansas State University

Researcher Quotes

―Weed control was good, especially in terms of gaining

early season control to minimize weed interference

and allow flexibility in a postemergence herbicide

application.‖

—David Jordan, North Carolina State University


―I put Fierce beside an untreated check, and the line was very defined.

The grass and broadleaf control was excellent.‖

—James Day, Bradgate, IA

―Fierce did a great job. Untreated check was solid weeds.‖

—Kelly Cooper, Forman, ND

―We have a real problem with Roundup®-resistant waterhemp, and

Fierce appears to be the answer to that problem. I applied it preemerge

and had total control.‖

—Joe Shryock, Columbia, MO
