Sustaining Superior Weed Control Technology

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:
- 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.
“Since the launch of the Enlist weed control system, we have strongly advised growers to use a complete program approach, including tank mixing Enlist One herbicide with another broad-spectrum mode of action like glyphosate or glufosinate,” Jungman says. “By including multiple modes of action against weeds, we can maximize the longevity of the Enlist trait.” - 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 grower access and use of trait technologies.The PUG is updated annually to ensure growers and retailers have the most up-to-date information at their fingertips.
- 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, they bring additional benefits to farmers 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 tank mix with either glufosinate or glyphosate so that 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.” - 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,” says Tubbs. “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:- Online webinars
- Self-paced training material
- In-person events, field days and training meetings
- Access to Enlist field specialist expertise and guidance
- 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 www.seedipalliance.com. Corteva works with a third-party organization to investigate validated tips and to conduct TUA authorized audits.
Stewardship will help ensure farmers can rely on the Enlist weed control system for years to come. Help your customers stay on track by following the TUA, PUG and product labels.
