Corn growers struggling to achieve good weed-control outcomes in fields under highly variable weather conditions have a new tool to help in the process – Resicore REV from Corteva Agriscience.
The herbicide premix, formally introduced by the company on Wednesday, can be used as a preplant, pre- or postemergence herbicide on corn up to 24” tall in a variety of agronomic programs (conventional, reduced and no-till), reports Nick Burke, U.S. corn herbicides product manager for the company.
“Resicore REV brings that proven weed control efficacy farmers have come to trust with Resicore herbicide, plus increased application options which will allow them to tailor weed-control programs to fit their acres,” Burke says.
Resicore REV features three active ingredients and modes of action – clopyralid (Group 4), mesotrione (Group 27) and acetochlor (Group 15), which is encapsulated for increased crop safety.
Burke says the herbicide controls more than 75 tough broadleaf weeds and grasses, including herbicide-resistant weeds like Palmer amaranth, waterhemp and marestail, for up to eight weeks.
In addition, Resicore REV gives farmers the ability to customize their weed-control programs with compatible products such as atrazine, glyphosate and other key corn herbicides, Burke says. The new herbicide also features tank-mix compatibility with micronutrients, including UAN and Ammonium Thiosulfate (ATS).
Rigorous Application Trials
Eric Scherder, U.S. crop protection launch leader for Corteva, says the company has invested in rigorous application trials to make sure farmers and other applicators have the “best possible experience” at application timing.
“Our R&D group not only has done this in the lab, but they’ve also done this under field settings with real-world equipment and under real-world scenarios,” Scherder says.
During the 2024 season, the company is taking its efforts to help farmers have a good experience with the herbicide a step further.
“We’re working with our sales team here in 2024 to go out and work with select retailers and growers around the Corn Belt to ensure that we’re really trying this product under real-world conditions, the wide range of applications and equipment (that’s feasible) and with all the available tank-mix partners,” Scherder says. “We’ve seen tremendous, tremendous results so far.”
Scherder says Corteva realizes farmers need wider application windows for herbicides, given the wide-ranging weather conditions they encounter today.
“Having that wide application window from preplant all the way up to 24” gives corn growers that peace of mind knowing they don’t have to try to switch out a herbicide program mid-season, because they’ve already gone past the growth stage,” says Scherder.
