Syngenta rolls out new herbicide

Acuron Flexi offers pre- and post-emergence residual control of tough weeds in corn.

Syngenta is rolling out Acuron Flexi for 2016. The name of the herbicide was announced during the Ag Media Summit in Phoenix this week where industry media are gathered for their annual professional improvement meeting.

The product, which is pending EPA registration, will offer pre- and postemergence residual control of difficult weeds in corn. The company has already had success with Acuron, which has four active ingredients and three modes of action. Acuron Flexi drops one active ingredient - atrazine - and provides two effective modes of action for areas where atrazine application may be limited.

Farmers in areas where atrazine may be limited will be able to use Acuron Flexi in 2016.

The product includes three active ingredients - bicyclopyrone, mesotrione and s-metolachlor. The bicyclopyrone is for burndown plus residual offering consistent control of large-seeded broadleaf weeds in corn. Mesotrione is for burndown and residual control of broadleaf weeds. And s-metolachlor offers residual control of annual grasses and small-seeded broadleaf weeds. Benoxacor corn safener is also included in the package.

Gordon Vail, technical product lead for herbicides, Syngenta, notes in a media release: "Where registered there will be no geographic or soil-type restrictions for using Acuron Flexi. Farmers will be able to rotate a variety of crops following an application of Acuron Flexi and they will have a wide application window from 28 days preplant up to 30-inch corn."

Acuron Flexi can be tank mixed with atrazine or glyphosate if needed, and offers farmers added flexibility as they consider rotational crops and geography when selecting herbicides.

Ryan Lins, Syngenta R & D scientist from Rochester, Minn., has been testing the product since 2013. "Farmers in certain areas of the Corn Belt - like parts of Iowa, Minnesota and Wisconsin - will find this product especially appealing, since they are limited from using atrazine because of carryover," he says. "That flexibility coupled with its long-lasting, consistent residual control, make Acuron Flexi an exciting new solution for controlling problem weeds."
