Syngenta Releases Acuron Corn Herbicide

Syngenta Releases Acuron Corn Herbicide

Syngenta recently received federal EPA registration for its new Acuron corn herbicide.  

Acuron includes four active ingredients: bicyclopyrone (group 27), mesotrione (group 27), s-metolachlor (group 15) and atrazine (group 5). This offers three different modes of action against weeds.

Bicyclopyrone is a newly registered ingredient. It is an HPPD inhibitor and provides action against broadleaves like waterhemp and Palmer amaranth. Research on bicyclopyrone began in 2006 with the intention of including it in Acuron. Testing and development began in 2011 with more than 700 trials for the Acuron herbicide.

Acuron is available for the 2015 growing season for a limited launch. Since the season is well underway, timing is important if you plan to use the herbicide.

“Our goal was to be flexible,” said Gordon Vail, technical product lead on Acuron. “It’s actually a pre- and post-emergence herbicide.”

Pre-emergent, farmers can use Acuron 28 days prior to planting and up to 12” tall post-emergence. Vail recommends using it pre-emergence since it is easier to control a smaller weed and it gives corn a clean start. Acuron has a product safener that allows it to be used in field corn, seed corn, sweet corn and yellow popcorn.

As of today, Acuron is approved in 32 states including: Colorado, Delaware, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Michigan, Minnesota, Mississippi, Missouri, Nebraska, Nevada, New Hampshire, New Jersey, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Vermont, Virginia, West Virginia, Wisconsin and Wyoming. Additional state registrations are expected to follow soon.
