Find Your Fit: Beat Resistant Weeds with Fierce® Herbicides
Targeting yield-robbing weeds with a premium preemergence herbicide offering multiple effective modes of action helps ensure competition from weeds such as Palmer amaranth or waterhemp won’t reduce soybean yield potential. Effective weed control is also critical to minimizing herbicide resistance.

“As Mother Nature evolves, managing weed resistance is critical. Growers have been stepping up in their willingness to invest in multiple effective modes of action,” says Joe Short, herbicide strategy team manager for Valent U.S.A. “Managing weed resistance is going to be critical now and in the foreseeable and long-term future for agricultural production to be successful.”
Including Fierce® Herbicides in a season-long soybean weed control program is one way to help keep resistance at bay.
Fierce Herbicides from Valent U.S.A. offer multiple effective modes of action to combat resistance development and control tough broadleaf weeds and grasses, with up to eight weeks of residual activity to help ensure weeds stay controlled. Fierce Herbicides also fit well into conservation tillage and Integrated Pest Management (IPM) systems.
Three distinct formulations, all offering effective control at low use rates, ensure growers can find their Fierce fit based on their unique agronomic and geographic needs.
“With the Fierce brands, we’re looking at six to eight weeks of residual control, whether it be waterhemp or Palmer amaranth,” Short says.
Fierce® EZ Herbicide and Fierce® MTZ Herbicide are liquid formulations designed for easy tank mixing and superior control of Palmer amaranth and waterhemp. Fierce MTZ adds a third mode of action for enhanced control of marestail, kochia and Russian thistle.
“As weed pressure increases, especially with tougher-to-control species, Fierce MTZ really stands out,” Short says. “It’s worth the investment because adding that third effective mode of action increases the overall probability for control.”
For growers seeking a dry formulation, Fierce® XLT Herbicide delivers effective control of large-seeded broadleaves such as ragweed and winter annuals.
