EPA has registered Acuron corn herbicide for control of waterhemp, giant ragweed and Palmer amaranth and other difficult weeds, maker Syngenta said this week.
Acuron has been shown to control more than 70 weeds, including broadleaf and grass weeds like marestail, kochia, morningglory and waterhemp, in addition to Palmer amaranth and others.
"Current herbicides are losing effectiveness, and it's not unusual for us to see growers spending as much as $60 per acre or more on herbicides for corn," says Gordon Vail, Ph.D., technical product lead for Syngenta. "The best strategy in this scenario is to use a high-performing pre-emerge herbicide like Acuron that will stop weeds before they start, and we're excited we can now offer it to growers."
Palmer amaranth, which produces up to 100,000 seeds per plant and can grow as fast as 3 inches per day, has been a serious challenge for growers, Syngenta says, but notes that Acuron has been shown to outperform competitive products on Palmer amaranth and other difficult weeds.
Three modes of action
Acuron uses novel chemistry bicyclopyrone, which complements the other three active ingredients in the premix to target a wider range of weeds than previous products. The four active ingredients and three modes of action in Acuron deliver a multi-targeted approach to weed control, while reducing the overall rates of certain herbicides.
As one of six commitments of The Good Growth Plan announced in September 2013, Syngenta said it is committed to making crops more efficient with a goal of increasing the average productivity of the world's major crops by 20% without using more land, water or inputs.
Syngenta believes the better level of weed control made possible by Acuron will be a critical component in helping farmers manage their operations and make corn production more sustainable.
State registrations for Acuron are still pending, and supplies for 2015 will be limited.
In the coffee shop, it is known as Palmer pigweed. In university circles, it is referred to as Palmer amaranth. Whatever you want to call it, this weed is the No. 1 weed to watch.
