At Corteva Agriscience, we’re committed to bringing farmers innovative technologies that help meet the challenges of a changing industry. That commitment comes with the responsibility to preserve the longevity and efficacy of those technologies.

As adoption of the Enlist® weed control system increases, farmers across the country are experiencing the benefits of this superior trait technology. Continued stewardship from all parties involved is now critical in ensuring the trait and herbicides remain viable. A foundation of good stewardship is weed resistance management.

“Weeds like waterhemp and Palmer amaranth are just waiting for us to take our foot off the gas,” says Scott Jungman, Enlist® field specialist. “Keeping trait and herbicide stewardship top of mind will help ensure the Enlist weed control system remains effective for years to come.”

Here are five ways you can help ensure the longevity of the Enlist weed control system:

  1. Adhering to the Technology Use Agreement (TUA) and product label. Growers are required to sign Corteva TUAs prior to obtaining access to intellectual property-protected products and traits from Corteva. The TUA for the Enlist weed control system outlines herbicide use requirements that benefit growers by preserving the technology.

    Saving harvested Enlist E3® soybeans for replanting, planting or reselling saved Enlist E3 soybeans and the improper promotion or use of non-Enlist 2,4-D herbicides on Enlist crops are all violations of the TUA. Any confirmed violations of the TUA are subject to review and may result in a loss of access to the Enlist trait technology.

    Planting professionally produced, certified seed is the best way to ensure the highest-quality crops, improved yields, and continued seed development to drive farm productivity. Learn more about the importance of adhering to TUAs at
  2. Downloading and/or printing a copy of the Product Use Guide (PUG). Following the procedures in both the PUG and the TUA is essential to maintaining access and use of trait technologies. The PUG is updated annually to ensure you have the most up-to-date information at your fingertips. 
  3. Creating a weed control program approach that maximizes the value of the Enlist® trait. Enlist® herbicides are in a class above other products containing 2,4-D. Not only are they effective against difficult weeds but also, they bring additional benefits to growers and the environment, such as tank-mix flexibility and reduced drift potential. However, that does not mean they should ever be used alone.

    “Enlist herbicides can do the heavy lifting,” Jungman says. “The 2,4-D choline found solely in Enlist herbicides is highly effective against a broad spectrum of broadleaf weeds like waterhemp, Palmer amaranth and ragweed species. However, we still ask growers to use it in a tank mix with either glufosinate or glyphosate so we have a multiple-mode-of-action approach. Dead weeds can’t breed.”

    Corteva Agriscience Market Development Specialist Will Tubbs agrees. “Relying on just one herbicide will accelerate herbicide resistance within a field. That’s why we always promote using a two-pass program that includes multiple effective modes of action and overlapping residual herbicides in each application,” he says.
  4. Taking advantage of educational opportunities. “Herbicide resistance in weed populations is an ever-evolving issue in crop production and will not be going away anytime soon,” Tubbs says. “The Enlist weed control system is extremely effective, but as weeds continue to evolve, we must do the same.”

    There are several ways to stay updated on best management practices with the Enlist weed control system. These include, but are not limited to:
  5. Submitting any reports of misuse. Growers and others can anonymously report misuse of seed technology — as well as unauthorized use of non-Enlist 2,4-D products with Enlist® crops — by contacting an industry tip line established by the Seed Innovations and Protection Alliance (SIPA). The tip line number is 1-844-733-3847. Growers can also report misuse at Corteva works with a third-party organization to investigate validated tips and to conduct TUA authorized audits.  

Stewardship will help ensure growers can rely on the Enlist weed control system for years to come. Reach out to your local Corteva Agriscience representative or visit to learn more about our commitment to stewardship.
