Dow AgroSciences Reveals Name Of New Residual Corn Herbicide
Dow AgroSciences announced July 14 that its new corn herbicide, previously referred to as GF-3471, will be named Resicore™ herbicide. Registration for this herbicide is expected in 2016.
Dow AgroSciences field trials show Resicore controls difficult weeds, including lambsquarters, waterhemp, Palmer amaranth, and marestail, with a novel formulation of three active ingredients.
According to the product’s technical bulletin, the proposed label will include sweet corn and yellow popcorn along with field corn, field seed corn, and field silage corn.
“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% efficacy rating on many common weeds found in Midwest fields such as waterhemp, marestail, giant ragweed, and Palmer amaranth.
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.
“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.”
