Development of the Enlist™ Weed Control System Leads to a Better Way Ahead

When launching the Enlist™ weed control system, developers followed a “measure twice, cut once” philosophy. Their responsible, measured approach is why Enlist™ crops and herbicides are showing farmers there’s a better way ahead.

“We know the power in launching the entire system – trait and herbicide – together cohesively,” says Shawna Hubbard, Corteva herbicides trait product manager. “All aspects of Enlist technology are proprietary to Corteva, created to work together for effective weed management."

Hubbard says the power of the system comes from the relationship between the trait and the herbicide.

“Enlist One and Enlist Duo herbicides were made to be used specifically with Enlist corn, Enlist cotton and Enlist E3 soybeans,” she says.

The reason these herbicides are so effective against tough weeds is that they’re based on the foundation of 2,4-D, developed in the 1940s. Enlist developers have a long history of working with 2,4-D esters and amines, knowing the strength of the systemic control of broadleaves with the active ingredient.

“They developed a unique product in 2,4-D choline,” Hubbard says. “It features near-zero volatility, significantly improving on the previous forms of 2,4-D to create a product that would eventually be sprayed on tens of millions of acres, with confidence that it would not get up and move after application."

Enlist herbicides are built to land and stay where they’re sprayed. Enlist Duo® herbicide is a convenient blend of 2,4-D choline and glyphosate. Enlist One® herbicide is a straight-goods 2,4-D choline that offers a critical benefit – tank-mix flexibility. Farmers can tank-mix Enlist One herbicide with glyphosate, with Liberty® herbicide (glufosinate), with an AMS or with any of more than a thousand other products. For more information, visit

Another key factor that Hubbard points out is the ability for third-party researchers to assess Enlist herbicides before commercialization.

“We believe collaboration with the industry is important,” Hubbard says. “Researchers at universities had access to Enlist herbicide as early as 2007. Some universities conducted volatility studies as early as 2011.”

In addition, the developers of Enlist technologies worked with grower groups, ag organizations and producers of specialty crops to ensure these herbicides reacted as expected.

“We continue to work with third parties to maintain confidence in our weed control and on-target properties,” Hubbard says. “Third-party access is important to give farmers and applicators peace of mind that Enlist herbicides have been thoroughly tested.”

This means farmers can be confident the system will work as expected.

“It goes back to who we are, how we want to treat customers and why it matters going forward,” Hubbard says. “We’ve committed to being careful, thorough and responsible. Growers deserve more, and with Enlist, we’re prepared to dominate the field in 2021.”
