In 2014, Acuron corn herbicide from Syngenta, which features four active ingredients, including new bicyclopyrone, and three complementary modes of action, was evaluated at 167 plot locations. These locations included 95 on-farm Syngenta locations, 54 university locations and 18 distributor locations spread across 35 states.

The 2014 trials are the latest in the product’s thorough evaluation, which has included more than 700 total trials held across the country over the past several years. Acuron is expected to receive EPA registration in time for use during the 2015 growing season, and first-year supplies are expected to be limited.

“We’ve partnered extensively with universities on trials and have also conducted a number of our own on-farm trials throughout the Midwest,” said Josh Putnam, Syngenta agronomic service representative in Michigan. “This year, I had an Acuron field trial in Mason, Michigan, and it provided comprehensive control of the toughest weeds in our corn cropping systems.”

Gordon Vail, Ph.D., Syngenta technical product lead for herbicides, has traveled to a number of Acuron trial locations this year. “I have visited a lot of Acuron-treated fields, and I’m seeing consistent results. The product has continually shown improved, more consistent control of the toughest weeds in corn, such as giant ragweed, morningglory, Palmer amaranth and waterhemp,” said Vail.

Mark Lawson, Syngenta agronomic service representative in Indiana, coordinated a 2013 Acuron trial and said, “The farmers and retailers who have seen my trials are very interested in learning more about Acuron, because it controls the weeds they are most worried about, like waterhemp, Palmer amaranth and marestail, and it provides a very wide window of control.

The product was developed in response to the expanding problem of weed resistance and difficult-to-control weeds and the resulting increase in demand for residual herbicides with multiple modes of action. With four active ingredients, three complementary modes of action and a corn safener, Acuron will be labeled to control more than 70 broadleaf weeds and grasses in corn, including resistant weed biotypes.
