Overlapping herbicide residuals helps ensure weeds remain controlled through soybean canopy closure, maximizing yield potential. Valent U.S.A.’s portfolio of residual herbicides gives growers flexibility across trait systems, setting the stage for clean fields well into summer.

“Making sure an effective preemergence herbicide is out there to control weeds is critical,” says Will Griffin, row crop segment manager for Valent U.S.A. “As that plant continues to grow, a second shot over-the-top with Perpetuo^® Herbicide continues that broad-spectrum weed control, helping growers improve productivity.”

Choosing Fierce^® Herbicides for preemergence weed control can help growers get a clean start, minimizing competition for sunlight and nutrients while providing up to eight weeks of broad-spectrum control of tough, resistant small-seeded broadleaves and grasses.

Applied as an early postemergent, Perpetuo^® Herbicide overlaps the preemergence residual, preserving broad-spectrum control of yield-limiting weeds such as Palmer amaranth, lambsquarters and velvetleaf.

“It gives growers flexibility,” says Ben Meriweather, sales representative with Valent U.S.A. “Let’s say a grower sprays Fierce two or three weeks before planting. That grower can plant knowing the post shot of Perpetuo, depending on weed spectrum and expected rainfall, can go out anytime between 21 to 30 days after planting.”

Overlapping residuals also help prevent hard-to-control weeds, including Palmer amaranth, from emerging, ensuring a clean seedbed through canopy closure.

“Preemergent herbicides make everything work better,” Griffin says. “When you’re not fighting large weeds, soybeans can emerge and grow without competing for nutrients.”

A Sustainable Plan

Overlapping residuals can reduce trips across the field, limit the need for tillage and incorporate multiple modes of action—all important components of a sustainable production plan.

“Sustainability has been a major focus in agriculture over the last several years,” Meriweather says. “Preemergent herbicides like Fierce help reduce field passes and overall fieldwork.”

Using overlapping residuals with multiple modes of action can also help minimize resistance development.

“Across geographies—from the Dakotas to the Delta and into the Southeast—using multiple modes of action is key to managing weed resistance,” Griffin says. “Fierce offers two modes of action, with options like Fierce MTZ or Fierce XLT adding a third. That provides another layer of protection, not just preemergence but also postemergence with Perpetuo.”

“Sustainability is about making sure we have solutions that support both growers and their profitability,” Griffin adds.
