Enlist™ Cotton Successes Set the Stage for Future Use of Enlist E3™ Soybeans

By David Hillger, Ph.D., Field Specialist

The Enlist weed control system has continued to prove its worth in 2018. Cotton farmers lead the way, adopting the technology successfully on a wide scale throughout the Cotton Belt.

As we prepare for the third full commercial year of the Enlist system in cotton, that launch can provide a preview of what to expect when Enlist E3 soybeans are fully commercialized. In 2018, cotton farmers planted 1.5 million acres of PhytoGen W3FE cottonseed, which includes the Enlist trait. Rapid growth means more than 70 percent of the PhytoGen upland portfolio was Enlist cotton this year, and Enlist cotton acres tripled vs. 2017.

The Enlist team working in the Corn Belt learns from our counterparts in the South, who have been advising retailers, applicators and growers throughout these couple of years. We can use their experiences and help retailers prepare their customers to succeed with Enlist E3 soybeans, once we fully commercialize them.

Like Enlist E3 soybeans, Enlist cotton features three herbicide tolerances – 2,4-D choline, glyphosate and glufosinate. Cotton growers are using Enlist One and Enlist Duo herbicides as cornerstones of a program approach. Growers who implement weed control programs delivering multiple modes of action not only obtain better weed control during the growing season but also help curb the development of resistant weeds in future years.

As we look forward to full commercialization of Enlist E3 soybeans, consider these key learnings from cotton country:

  1. Help customers make a plan when incorporating a new trait technology. Urge them to use the Enlist weed control system on areas with glyphosate-resistant weeds. Consider the surrounding landscape and nearby susceptible crops.
  2. Develop and follow a weed resistance management plan. This involves using multiple herbicide modes of action to curb the development of resistant weeds.
  3. Follow the label when applying Enlist herbicides. These products offer inherent low volatility and a better formulation for drift reduction. However, applicators must always follow all label requirements. It’s critical that they pay attention to wind speed and direction, equipment cleanout and environmental conditions. Those who have used the system tell us when they follow the label, they have success in the field.
  4. Fully use all trait tolerances. If your farmers like glufosinate-tolerant soybeans, Enlist E3 soybeans are a natural next step with added herbicide tolerances. Farmers can tank-mix Enlist One herbicide with glufosinate or take advantage of the convenient blend of Enlist Duo herbicide to apply 2,4-D choline and glyphosate easily.
  5. Complete training before it’s time to spray. Retailers, applicators and farmers should take advantage of education and training opportunities before using the Enlist weed control system. Retailers can complete Enlist 360 training online for an overview of the system. They can send their customers to Enlist.com to learn more, too.

Retailers can help their customers evaluate new technology options if they understand those options themselves. We urge retailers to take advantage of the Enlist 360 training, found at Enlist.com. The Enlist weed control system truly is different from traditional 2,4-D and other herbicide trait systems.

We look forward to full commercialization of Enlist E3 soybeans in the future. We’re focused on preparing the industry to succeed with these elite soybean varieties containing the Enlist trait. As we continue to increase Enlist E3 soybean production and expand genetic lines, we’re committed to educating and training users how to incorporate the system confidently and successfully on their farms.

A clean spring starts with a preemergence herbicide

As your customers evaluate this season’s yield and adjust their weed control plans for next season, reinforce the value of a preemergence herbicide with them for a clean start. By relying only on postemergence applications, waterhemp, marestail and other common weeds can start robbing corn and soybean yield right after planting.

Spring is a vulnerable time for crops as they require a strong start to thrive for the rest of the season. In an April poll on OperationCleanFields.com, most retailers — 58 percent — selected waterhemp as their customers’ most challenging weed followed by marestail at 23 percent.

Marestail is generally considered the most difficult weed to control if it can overwinter into the spring. When this happens, marestail grows rapidly as temperatures warm, robbing soil of two critical inputs: moisture and nitrogen. Since marestail can germinate throughout the entire year, it’s important for retailers and farmers to scout for it year-round and identify it early in the rosette stage for effective control.

The photos below were taken in McLean, Nebraska, on July 9, 2018. McLean is in the Northeast part of the state and where marestail is one of the biggest weed challenges. The fields shown received spring applications of Sonic® herbicide in soybeans and Resicore® herbicide in corn to allow the crops to grow with less weed competition.

“To reduce the spread of resistant weed populations, such as marestail and waterhemp, farmers should plan their herbicide control and crop rotation for more than a single year at a time,” says Dave Roome, customer technical specialist, Corteva Agriscience, Agriculture Division of DowDuPont. “The most important tip for farmers fighting these weeds in their corn or soybean fields is to act early by starting with a preemergence herbicide to keep weeds small and easier to control.”

Talk with your Corteva Agriscience territory manager about how you can help your customers get a jump on weeds in corn and soybean fields next spring. For more information about Resicore and Sonic, visit PowerOverWeeds.com and BattleWeeds.com, respectively.

Weed of the Month: Giant Ragweed

  • giant ragweedCommon name: Giant ragweed
  • Scientific name: Ambrosia trifida1
  • Grass or broadleaf: Annual broadleaf
  • Giant ragweed grows in the Midwest and Eastern regions of the United States, but it is most heavily concentrated in the eastern Corn Belt states like Indiana and Illinois.2
  • Germination timing: Giant ragweed is traditionally an early season weed; however, its growing season is expanding. Giant ragweed typically sprouts in early May but has been seen as early as March. The weed can continue to cause issues through late July and can impede harvest if not controlled.2
  • Competitiveness: Giant ragweed is one of the most competitive weeds in corn and soybeans.
    • Two giant ragweed plants within a 110 square feet area can reduce corn yield by 13 percent.2
    • Soybean yield can be reduced by 50 percent when there is just one giant ragweed plant within a 110 square foot area.2
  • Giant ragweed can grow 1-5 feet taller than competing plants and can reach heights of up to 17 feet tall.2

Fast facts

  • When a giant ragweed plant first emerges, it can be identified by its spatulate cotyledons. These cotyledons are spoon-shaped and can range from 1 to 1 ¾ inches long.2
  • Giant ragweed always has three distinct lobes but can show up to five lobes that grow in an opposite arrangement.2
  • According to WeedScience.org, the first confirmation of herbicide resistant giant ragweed in the United States was in an Indiana soybean field in 1998.
  • Giant ragweed is a monoecious plant, which means that separate male and female flowers can found on a single plant.2
  • Giant ragweed seeds can be identified by their points and ridges that make them look like small crowns.2

Weed management tips2

  • Use multiple modes of action:
    • One of the best ways to fight giant ragweed is to use multiple modes of action in a herbicide program with both preemergence and postemergence herbicides.
  • Scout for weeds:
    • Look for giant ragweed two weeks after the postemergence herbicide application and determine if another application is needed.

Resistance Statistics*

  • According to to WeedScience.org, herbicide-resistant giant ragweed has been documented in corn and soybean fields in 13 states: Arkansas, Illinois, Indiana, Iowa, Kansas, Kentucky, Minnesota, Mississippi, Missouri, Nebraska, Ohio, Tennessee and Wisconsin.*

*Resistance confirmation does not include all weeds and may vary among different areas of each state.

Control high-anxiety weeds through fall burndown treatments

Kent Bennis

Fall often consists of reflection and planning for your customers. This entails evaluating their current season and preparing for the next. However, for many soybean farmers in the Midwest, fall is also the time they may be experiencing the pain of actively growing weeds, including marestail.

We highly recommend that your customers implement fall burndown treatments to help ease their weed anxieties. Specifically, postharvest burndown treatments can reduce customers’ worries by providing thorough weed control in recently harvested fields. And when farmers combine a fall burndown treatment with a spring residual herbicide, they will experience cleaner fields through planting.

Here are some key benefits of fall burndown treatments to share with your customers:

  • Lessens weed pressure so fields are ready to plant as soon as farmers are ready
  • Reduces the dead mat of weeds common after a spring burndown to speed soil warming and dryout, especially in no-till fields
  • Keeps soil moisture available for the young crop
  • Helps create a warmer, drier seedbed for uniform emergence and better seedling vigor
  • Decreases insect pressure by eliminating the conditions insect populations use to become established

When implementing a fall weed control program, it’s critical to find a herbicide solution that offers a thorough spectrum of control on postharvest weeds. A herbicide such as Elevore® uses a systemic approach that works to kill a broad range of weeds from the inside out, including actively growing marestail up to 8 inches tall and other ALS- and glyphosate-resistant species.

The results provide farmers with numerous benefits, including a more streamlined workload with fewer hours of spring work, better-prepared fields at planting and the opportunity for increased yield at harvest.

Herbicide Lessons Lessen Farmers’ Concerns

Growing knowledge about the Enlist weed control system remains vital as Corteva Agriscience, Agriculture Division of DowDuPont, continues to prepare the market for the large-scale commercialization of Enlist E3 soybeans.

Corteva Agriscience will broadly license Enlist E3 soybeans following Chinese import approval of the Enlist E3 soybean trait. Making this trait widely available to farmers requires seamless collaboration with seed companies: The technology must be available in the best genetics over a wide range of maturities. That’s why the company is engaging now with seed companies that plan to add Enlist E3 soybeans to their product lineups.

Ensuring the Enlist technology is in elite soybean (as well as corn and cotton) genetics will help farmers, applicators and retailers who evaluate the Enlist trait be more profitable and successful. 

As this technology gets into the hands of more farmers – and the retailers they trust – it builds comfort with the system and prepares for continued expansion of Enlist crop acreage.

Part of this effort is continued access to education and tools that help users get more out of the Enlist system. Field planning, best management practices, application education and advice help farmers position Enlist crops to perform as promised. This includes on-target application, excellent weed control, exemplary crop tolerance and the opportunity for top yield.

Education from the start
From the beginning, education and product stewardship have been critical pillars of this technology. As a key part of the Enlist weed control system, the Enlist Ahead management resource provides an array of tools to help retailers, farmers, and applicators understand how to use this technology — including Enlist herbicides — appropriately and effectively.

As individual Enlist crops come to market, the emphasis on education, training and stewardship expands. Committing resources to these efforts allows the company to launch these crops in a careful, responsible and measured way.

“When we work with farmers, we emphasize field planning, a program approach and adherence to all label requirements, including downwind buffers,” says Andy Asbury, a field specialist for Illinois. “Farmers are seeing how this system works in their fields.”

Specialists such as Asbury provide tools and training to help ensure farmers can use this technology confidently.

“We can help farmers understand label requirements for our products,” says Steve Snyder, a field specialist who covers the upper Midwest. “In addition, we offer online resources so growers in the field can get quick access to information on their tablets or smartphones.”

Customers are gaining experience with Enlist crops. Enlist Ahead tools provide a wealth of information to help users feel secure when using this much-needed and extremely effective weed control technology. Learn more about the Enlist Ahead management resource by visiting Enlist.com

Enlist education efforts

Continuing education efforts highlight the growth of the Enlist weed control system. Collaboration with seed companies and in-the-field training are helping growers, applicators and retailers understand how to use this technology most effectively and successfully.

Three steps to identify a proven nitrogen stabilizer

Nitrogen stabilizers are one option to protect nitrogen; however, the market is saturated with products that claim to protect nitrogen. With fall purchasing decisions around the corner, Corteva Agriscience, Agriculture Division of DowDuPont, has identified key criteria to help farmers select a proven nitrogen stabilizer that is right for them.

Weeding through the myriad of stabilizer products can be tricky, and timely factors like commodity prices, trade negotiations and nutrient management regulations make finding the best option even more important. Corteva Agriscience recommends that farmers use three criteria in determining the right nitrogen stabilizer to use:

  1. Leverage University-supported research
    Use stabilizers that have been rigorously tested and proven by universities. Farmers should ask their retailers to share academic research that supports the claims that are being touted.
  2. Check labeling to ensure it meets EPA registration guidelines
    Use stabilizers that also follow EPA registration guidelines. These guidelines require robust documentation and research to support claims that relate to the effectiveness of a nitrogen stabilizer product.
  3. Prioritize value
    The current economics of farming may not be as rewarding as a few years ago, so every penny matters. Stabilizers can be viewed as an insurance policy to protect crop yield and preserve a farmer’s investments. Whether you’re concerned about nitrogen being a yield-limiting factor or concerned about nitrogen loss impacting water quality, nitrogen should always be protected.

Two options that meet this criteria set are Instinct® and N-Serve® nitrogen stabilizers. Instinct and N-Serve maximize nitrogen by extending its availability for up to eight weeks, during critical growth stages for corn and wheat, helping crops deliver the maximum yield at harvest.
