Farmers face an ever shrinking toolbox in the fight against resistant weeds, but a new option is nearly ready for crop fields – the Enlist weed control system. Enlist Duo herbicide utilizes glyphosate and a new 2,4-D formulation to stop resistant weeds and hard to control weeds. With the completion of the review of cotton, the regulatory process is closing in the U.S. for all three Enlist crops: corn, soybean and cotton.
“Enlist offers flexibility in terms of allowing growers to keep farming the way they’ve been farming. We’ve finally crossed all our hurdles with respect to deregulation in the U.S., although we’re still pursuing some herbicide registrations,” says Jonathan Siebert, Enlist sales leader.
Producer Trey Koger grows a variety of row crops on a wide range of soil types in Belzoni, Miss., and tested Enlist cotton in 2015. “This is going to be a very effective tool, but we still have to use common sense and be respectful of our neighbors. It’s a tool that’s going to be very effective for our operation in managing very difficult weeds. We’re still going to have to use residuals and can’t just rely on post programs.”
Koger emphasizes the necessity of yield, and not only weed control. “The genetics, germplasm and varieties all have to be there for us. The technology has to be complemented with yield, and it will likely be phenomenal as well, just like the weed control.”
William Lane farms 2,600 acres on the Louisiana line in southeast Arkansas and faces mounting weed problems from resistant Palmer pigweed. He grew Enlist soybeans on a test plot in 2015 and noted the near zero volatility of Enlist Duo: “We’ve proven this formula doesn’t have the volatility of old chemistries. It’s just not the same as traditional 2,4-D. This is a product that’s shown me that we can get ahead of pigweeds. If we do that, our yields will climb and so will profit.”
Lane documented glyphosate-resistant pigweed on his farm in 2006. He started using residuals with success in 2009, but couldn’t prevent a pigweed spread across his entire farm. One of Lane’s major expenses in 2015 is labor for hand-chopping pigweeds. He says Enlist Duo performed very well on Palmer at 6” and below. “We sprayed max rate behind the planter and then three weeks later at max rate, and then 10 days later with Liberty and it was as clean a field as I’ve ever had. There was no bad effect on the soybeans, period.”
Enlist cotton and soybeans offer tolerance to Enlist Duo herbicide and glufosinate. Enlist Duo harnesses Colex-D Technology, with minimized potential for drift problems. “The final hurdle for Enlist will be import markets because we’re committed to maintaining the grain channel,” says Siebert. “We do plan to launch in 2016.”
