Dow AgroSciences announced that its new corn herbicide, previously referred to as GF-3471, will be named Resicore herbicide. Registration for this herbicide is expected in 2016.
"Resicore is designed to control weeds throughout the season, says Luke Peters, corn herbicides product manager, Dow AgroSciences. "It will provide trusted residual control, resistance management and resounding yield potential as the core of growers' weed control programs.
Resicore will help growers control herbicide-resistant weeds through three nonglyphosate and nonatrazine modes of action. The active ingredients included in this novel formulation are acetochlor, mesotrione and clopyralid. Resicore is expected to offer flexible application timing from preplant to early postemergence.
In 2014 trials, Resicore herbicide had a 97 percent efficacy rating on many common weeds found in Midwest fields such as waterhemp, marestail, giant ragweed and Palmer amaranth.1
Currently, waterhemp populations have shown resistance to five different modes of action in 18 states. Additionally, resistance to multiple modes of action has been confirmed in Iowa, Illinois, Kansas, Minnesota and Missouri.2
"By implementing a weed control program that rotates modes of action and uses herbicides with residual control, growers can combat heavy weed pressure in corn fields more effectively, Peters says.
Scouting throughout the growing season is also essential to ensure timely herbicide applications and to identify problem fields for the following year.
"Waterhemp continues to top the list of troublesome weeds for corn growers, Peters says. "With three active ingredients that have never been included in a single product before, Resicore is a new, unique option for growers seeking control of waterhemp and other herbicide-resistant weeds.
