Instigate™ Herbicide Adds Flexibility for Weed Control in Corn

U.S. EPA grants registration for new option for tough weed control in corn in northern and eastern Corn Belt.

WILMINGTON, Del., Oct. 4, 2012 – Corn growers in the northern and eastern Corn Belt who are looking for more flexibility in crop production have a new tool: DuPont™ Instigate™ herbicide has received federal registration approval from the U.S. Environmental Protection Agency for application from preplant through early emergence for tough broadleaf and grass weed control in corn.

Instigate™ provides burndown plus residual weed control of hard-to-control broadleaf and grass weeds across a wide application window with excellent crop safety. As part of a tank-mix program, Instigate™ delivers season-long weed control that outperforms standard herbicide programs.

“Instigate™ gives growers extra flexibility to work around weather delays and busy schedules while keeping corn fields clean during the crucial weed-free period before crop canopy,” said John Chrosniak, regional director, North America, DuPont Crop Protection. “This is another example of how DuPont is developing products to meet growers’ changing needs and handle weeds that can reduce yield and overall productivity. Successful weed control and weed resistance management through strategic herbicide use are two steps that will help growers produce more to help meet the challenge of feeding our growing population.”

Effective at low use rates, Instigate™ includes multiple active ingredients, including a unique dry formulation of mesotrione. Instigate™ is formulated to add efficacy and deliver improved results when tank-mixed with full or reduced rates of most basic preemergence corn herbicide programs, including glyphosate, paraquat, atrazine and atrazine-containing products. Instigate™ offers season-long control when used in a program with DuPont™ Cinch® ATZ herbicide or with Breakfree® ATZ herbicide.

“Instigate™ can be tank-mixed with most standard preemergence corn herbicide products. By including Instigate™ in a preemergence program, growers can reduce the amount of standard preemergence herbicide needed by one-third or more,” Chrosniak added.

Through the TruChoice® Opportunity Program, Instigate™ is available with grower financing and other purchase incentives that will allow a grower to earn up to an 8 percent incentive on all DuPont Crop Protection product purchases.
