Corteva Agriscience is working with more than 100 independent seed companies to broadly license the Enlist E3™ soybean trait. These efforts will enable wide availability for 2020 and beyond, making Enlist E3 soybeans available to growers who need advanced weed control solutions.
The goal of bringing the benefits of Enlist E3 soybeans to growers in their preferred brands was established years ago, as early commercialization plans were drafted for the Enlist system. Corteva Agriscience is proud to work with seed companies to make Enlist E3 soybeans available to their customers. Enlist E3 soybeans fit across a wide range of geographies and maturities, helping growers everywhere achieve excellent weed control and strong yield.
We project that Enlist E3 soybeans will be planted on at least 10% of U.S. soybean acres in 2020. Farmers can visit Enlist.com for a list of seed companies who are offering Enlist E3 soybeans for the 2020 season. Enlist E3 soybeans also are available from Corteva Agriscience™ brands: Pioneer®, Mycogen Seeds, AgVenture, Dairyland Seed, Hoegemeyer Hybrids, NuTech Seed®, Seed Consultants and Terral Seed.
Offering exceptional weed control
The introduction of the Enlist E3 soybean trait into these seed company lineups will give an effective weed control option to soybean farmers from North Dakota to Texas and from Colorado to the Carolinas. Farmers who plant Enlist E3 soybeans can take advantage of Enlist™ herbicides to help manage tough and resistant weeds. When used in a program approach that includes a burndown application and preemergent applications of effective residual herbicides, Enlist herbicides will help growers keep weeds under control throughout the growing season.
Starting clean and applying preemergence residual herbicides sets the stage for applications of Enlist herbicides postemergence on Enlist E3 soybeans. Enlist Duo® herbicide is a combination of 2,4-D choline and glyphosate to control broadleaf weeds and grasses. Enlist One® herbicide is a straight-goods 2,4-D choline that offers additional tank-mix flexibility with other products such as glufosinate.
With the ability to use 2,4-D choline, glyphosate and glufosinate postemergence, soybean farmers can employ multiple modes of action against their most difficult weeds. Using multiple modes of action also retards the development of herbicide-resistant weeds.
Expanding flexible options
Making the Enlist weed control system broadly available through many seed organizations will give soybean farmers the opportunity to control tough and resistant weeds by using multiple herbicide modes of action.
Retailers can learn more about the Enlist weed control system and the companies producing Enlist E3 soybeans by visiting Enlist.com, following @EnlistOnline on Twitter or going to the Enlist YouTube channel.
Farmers who have experienced Enlist™ herbicides are seeing that – in addition to their other attributes – Enlist One® and Enlist Duo® herbicides control their toughest weeds.
“Enlist worked well again,” says Ben Hortenstine, an Illinois farmer who has used the Enlist™ weed control system for three years now. “I like Enlist Duo because I don’t have to worry about tank mixing. It’s convenient. The 2,4-D choline takes care of the broadleaf weeds, and the glyphosate takes care of grasses. It’s been working for us.”
Jack Kent of Arkansas has experience with both Enlist cotton and Enlist E3 soybeans. Weeds, particularly Palmer amaranth, present challenges in trying to achieve consistently high yield.
“Enlist herbicides are going to allow us to control our worst weed,” Kent says. “So far, the Enlist system has absolutely been bulletproof. It has done everything it’s supposed to do. I can’t say enough good things about that product. It’s the best herbicide that I have ever seen in my life.”
Indiana farmer Luke Liechty also has been impressed with Enlist Duo® herbicide.
“The control Enlist Duo provided was phenomenal,” Liechty says. Within a day of application, weeds were starting to curl. Within two weeks, they had wilted beyond recovery. “The biggest value for the Enlist program on our farm is confidence. It’s confidence knowing that I can go out there and control weeds that are difficult to control right now.”
Liechty says flexibility is another important benefit.
“I think a lot of American farmers love to have options, and when you utilize the Enlist program, you have options to control your weeds,” he says. “You’re not just relying on one mode of action. If you start with a good preemergence herbicide and follow with a postemergence application of Enlist Duo herbicide, you can really have phenomenal control of hard-to-control weeds.”

It’s been half a century since Mike Book’s family started farming in Dixon, Illinois. Today, Book continues the tradition as a third-generation corn and soybean farmer, alongside his brother Aaron and father Jim.
Over 50 years, the Book Family has endured countless successes and challenges in the field. One challenge that’s cropped up time and time again is weed control.
Like many other Midwest farmers, Book encounters waterhemp in his cornfields. Coming up with a reliable program to tackle waterhemp is easier said than done.
Waterhemp is a competitive weed in the pigweed family with known resistance to multiple herbicides. One female waterhemp plant produces 250,000 seeds, and left untreated, the weed can decimate corn and soybean yield potential.
To protect yield potential, farmers need a program that works to control waterhemp. Luckily, Book tried SureStart® II herbicide about five years ago and hasn’t looked back.
“It’s nice to use SureStart II on a wide variety of acres and know that it’s going to work,” he explained. Book sprays SureStart II, which has three modes of action, right after planting corn, followed by a second pass of dicamba.
The Illinois farmer says the straightforward application process makes his job a little easier.
“I like SureStart II because when I put it in the tank, I know it’s going to work,” Book said. “It decreases the chance of anyone messing it up.”
When it comes to cost, Book said, he appreciates that the herbicide is affordable when covering all of his acres and gets the job done right, saying, “We certainly like it and we like the price point.”
Book may not know what challenges the next 50 years of farming will hold, but, for now, he is working smarter, not harder on weed control with the help of SureStart II.

On June 1, 2019, after three years in the making, a new company was officially born: Corteva Agriscience. The name “Corteva” is derived from words meaning “heart” and “nature.”
Corteva is founded on the rich heritages of Dow, DuPont and Pioneer. Today, Corteva stands on its own as a leading seed and crop protection company after separating from DowDuPont.
Company leaders, including Jim Collins, Chief Executive Officer, celebrated the separation of Corteva into its own entity Monday, June 3, by ringing the opening bell on the New York Stock Exchange. It was an exciting moment, symbolizing a major step into a bright future.
Of the experience, Collins said, “Today marks the launch of a new kind of agriculture company, well-positioned to compete and win by providing farmers the complete solution they need for sustainable, long-term growth and improved profitability.”
More than 21,000 employees work for Corteva, which has a presence in 140 countries across the globe. Collins explained that each of those employees is dedicated to enriching the lives of those who produce and those who consume, ensuring progress for generations to come.
The new company has a strong focus on innovation, with an eye on expanding digital capabilities. Corteva will strive to be at the forefront of the newest and best crop solutions.
The company’s top commitments, however, will always be to farmers and to the land, especially precious natural resources. No matter how this company continues to grow in the coming years, nature will always remain at the heart.
With soybean fields planted, albeit late in a lot of cases, many farmers and retailers may be wondering how long the preemergence herbicides they applied will hold against tough weeds. It’s an important factor to consider when planning for any potential postemergence herbicide applications.
Recently, a soybean retailer submitted a timely question via Operation: Clean Fields around expected residual control of a top preemergence herbicide. Chad, a retailer in Minnesota, asked the question, and Jeff Moon, market development specialist with Corteva Agriscience, answered.
Q: When applied as a preemergence, how long of a residual can I expect using Sonic® herbicide?
A: Sonic herbicide has a labeled application rate of 4 to 7 ounces per acre. The length of residual will depend greatly on where your application falls within that rate spectrum. If you apply 4 ounces per acre, you can expect residual control to last between four and six weeks. From there, as a general rule of thumb, you can expect an additional seven to 10 days of control for every ounce per acre that the application rate increases. So, at the maximum rate of 7 ounces per acre, we’ve seen seven to 10 weeks of residual control when applied as a preemergence.
One benefit of that long-lasting residual control is it gives farmers a much wider window to make postemergence applications. It also keeps those later-season weeds small and easier to control, so you can stay on label with planned postemergence treatments.
Of course, both the amount of moisture received after application as well as the soil type can factor into the duration of residual control experienced.

It’s no secret nitrogen is one of the most important nutrients for a corn crop. Once nitrogen is lost, corn plants themselves may not be far behind. What seems to be a bit more secretive, or at least mysterious, is how nitrogen stabilizers work to keep as much of the nutrient as possible available for those plants.
It all comes down to simple science (well, simple for the scientists anyway; it takes just a little more explaining for the rest of us).
Corn uses nitrogen in two forms: ammonium and nitrate. Ammonium is preferable to corn, because it’s easier for plants to absorb and it’s less susceptible to loss. Nitrate is more easily susceptible to loss via leaching and denitrification. Unfortunately, there are strains of bacteria that convert ammonium into nitrate to use for their own nutrients.
Corteva Agriscience’s line of nitrogen stabilizers, called nitrogen maximizers, includes N-Serve® and Instinct®. Both products work below the soil to slow down those bacteria, ensuring the nitrogen can stay in ammonium form longer. The maximizers extend the ammonium’s useful life for up to eight additional weeks, keeping nitrogen near the corn’s roots for when the plant is ready to absorb it.
The result is that the corn crop can get the maximum out of the farmer’s nitrogen application and the farmer, in turn, can get the maximum out of his or her investment, leading to a profitable yield.
With an extremely rainy spring across much of the Corn Belt and with planting being significantly delayed, nitrogen is especially vulnerable to loss this season. So, it’s especially important to ensure your customers’ investments are as safe as possible. Nitrogen maximizers can help.
And as you and your customers look ahead to fall nitrogen applications, onward to 2020 planting, it’s a good idea to keep this information top of mind. To learn what nitrogen maximizers can do for your clients’ crops, visit NitrogenMaximizers.com.
