Syngenta Awaiting Registration on Two Herbicides: Acuron and Broadworks
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.
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.
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.
In addition, Syngenta will introduce a new herbicide to aid in resistance management, which will be marketed as Broadworks herbicide upon registration. The active ingredient, mesotrione, will be the first HPPD-inhibitor for tree nuts, stone fruit and citrus.
Broadworks aids in herbicide resistance management by controlling weeds that are resistant to other modes of action, such as glyphosate-resistant marestail and fleabane. It must be used as part of a weed management program that includes herbicides with different modes of action.
Broadworks is a systemic herbicide. It is readily taken up by the leaves, shoots or roots and is translocated in both the xylem and the phloem, complex tissues that perform transportation of food and water in a plant. Within 24 hours of application, as much as 88 percent of the applied material is translocated out of the treated zone and is distributed throughout the plant.
