Adam Schwering

Adam Schwering farms in Indiana with his dad and brother. His grandfather started the farm more than 40 years ago. The Schwerings practice a 50-50 corn-soybean rotation and are incorporating cover crops.. One reason they’re interested in Enlist E3 soybeans and the Enlist weed control system is that they try to stay proactive with their weed control program. They want to stay ahead of marestail and giant ragweed challenges.

  • Indiana

  • Soybeans

  • Marestail
    Giant ragweed

  • No-till/vertical till

Weeds like this have become a rare sight in Adam Schwering’s Enlist E3 soybean fields. The application of Enlist Duo® herbicide is causing them to wilt, shrivel and disappear, leaving nice, clean rows of soybeans

Enlist E3 Soybeans Pass the Eye Test, Controlling Persistent Marestail

Farmers driving down the state highway past Adam Schwering’s fields of Enlist E3 soybeans are taking notice. They’re seeing weed-free soybeans in an area where marestail continues to ravage almost every field.

“They’ll drive by our field and ask why our fields are so clean,” Schwering says. “We tell them it’s because of Enlist Duo. They’re getting more curious about trying it.”

Schwering is about as experienced with the Enlist weed control system as any farmer in the country. He’s been using the system for five years and has 450 acres dedicated to seed production for Enlist E3 soybean varieties this year.

Schwering likes the weed control he’s gotten from Enlist Duo® herbicide, including the way he was able to suppress the weed seed bank. He can see the difference in weed growth year over year.

“The product works,” he says. “This year, you can see where we sprayed Enlist Duo last year and where we didn’t. The weeds are in the untreated area but not in the field where we sprayed Enlist Duo.”

The biggest challenges the Schwerings face are rampant marestail and defiant giant ragweed. They use a program approach that involves a burndown with generic 2,4-D, glyphosate and Sonic as a residual. They come back postemergence with Enlist Duo, which combines 2,4-D choline featuring Colex-D® technology with glyphosate for two modes of action.

“We use Enlist Duo on top to take care of our problem weeds,” Schwering says. “We’ve talked about Enlist One – the straight-goods 2,4-D choline – but we haven’t tried it yet. We’re thinking about whether glufosinate would help, but it has a narrower spray window than Enlist Duo.”

Schwering sees interest growing in the Enlist system and Enlist E3 soybeans.

“Guys around here will likely try it now that Enlist E3 soybeans are approved,” he says. “I have neighbors who need to use it because of the weeds they’re struggling to control.”

Those neighbors who drive by Schwering’s Enlist E3 soybeans can see that the Enlist weed control system passes the eye test. That’s a spark for more growers in that part of the country to check out Enlist E3 soybeans for the 2020 season.

Enlist Duo™ herbicide took control of weeds in our soybeans

Enlist Duo™ herbicide was extremely effective in taking control of the weed pressure in our soybean field. In the future, we would like to plant most of our soybean acres with Enlist soybeans so we can use this new 2,4-D technology as part of our systems approach to stay ahead of glyphosate-resistant weeds.

We had weather issues this spring and couldn’t get spraying done when we would’ve liked.  The wide application window made it possible for us to utilize this new tool to knock down marestail and giant ragweed that we would have otherwise had difficulty controlling. We didn’t need to spend a lot of time measuring and mixing several different products together. The outcome netted us a clean, beautiful, weed-free field of soybeans.

Enlist Duo is a new formulation of 2,4-D so it is specifically formulated to help cut down on drift. We followed the label recommendation, put different nozzles on our sprayer to minimize drift and saw no drift whatsoever.

Quality of Enlist™ soybeans excellent at harvest

We’ve just started combining our Enlist™ soybeans. I think they’ll average in the low 60s. With another rain in August, they had the potential to yield 70 bushels per acre.

Enlist™ soybeans beginning to change

We’re just starting to see the Enlist soybeans reach maturity. We expect to harvest the field in about three weeks.

Dry Field Conditions

Pods are set on Enlist™ soybeans

The Enlist beans look really good. The fields are about as close to 100 percent weed free as you can get. Looks like there is a pretty good amount of pods that have set on all the plants. With a little cooperation in the weather over the next few weeks, we will have a good crop of beans.

August 16, 2015



Early this season was wet, and we’re now seeing our longest driest spell since March, it seems. Rains have slowed so much now. It wouldn’t hurt to have a nice shower this next week to help finish out the beans. With 1.5 inches so far in August, we are now over 21 inches since May 1.

The beans in our area look surprisingly good for all that they have been put through this year! I think our corn is suffering more than the beans, now especially. We are seeing a lot of firing on the bottom of our corn stalks.”

Our Weed Control can be Challenging

With no-till farming practices, our weed control can be challenging. By working Enlist Duo herbicide into our program, it gives us more options to get those tough weeds. We use Sonic herbicide as our preemergence, and Enlist Duo is an option for us to come in over the top.

Handling of Enlist Duo herbicide was easy

Handling of Enlist Duo herbicide was easy. We weren’t mixing 2-3 chemicals together in the tank. You just dump and go. It’s fast and effective.

For the application, we couldn’t ask for a better day – the weeds and soybeans were actively growing. We saw some speckling, but no puckering or chemical burn. It was less damage to the plant than we’ve seen with other products.

Wet Field Conditions

Planting Enlist™ soybeans

We planted our Enlist beans this past Friday and finished our corn on Friday as well. At least for the first time around! It’s been a wet May. Yesterday, we finished the rest of the beans and replanted about 50 acres of corn that had drowned due to the rain we’ve received.

It’s a good thing we finished yesterday because it is raining again this morning, and they are calling for chances of rain for the next eight days.

fair field conditions

Early spring herbicide applications

We started planting corn on our farm today. The ground conditions are decent, where we have good drainage tile but a couple days from ideal elsewhere. My dad and brother are still working on bean burndown and preemergence herbicide applications. We hope to start putting beans in the ground by middle of next week.

Fields benefit from cover crops

We seeded cereal rye cover crop on our Enlist soybean field last fall. We have three main goals for cover crops on our farm – capture any nitrogen we can, build organic matter and erosion control on some of our gently rolling fields. As you can see from the photo, the rye is doing an excellent job of capturing nitrogen. You can definitely see the streaks from anhydrous application last year.
