Corteva bringing new herbicide to market

JOHNSTON, Iowa — Corteva Agriscience announced the launch of a new herbicide option with two modes of action to expand farmer options for 2027.

The new herbicide, Enclosa, provides the first-ever combination of a proprietary encapsulated acetochlor, a Group 15 herbicide, and cloransulam, a Group 2 herbicide, to deliver weed control with up to four weeks of residual activity.

Enclosa has been granted approval from the U.S. Environmental Protection Agency and is now in the process of receiving state approvals.

With the launch of Enversa herbicide last year, farmers experienced how the proprietary encapsulated acetochlor from Corteva moves quickly off plant tissue to drive to the soil, establishing a residual barrier against weeds.

Building on the success of Enversa herbicide, Enclosa herbicide will feature a combination of encapsulated acetochlor and cloransulam in a convenient premix to provide farmers with residual and systemic control of more than 36 tough broadleaf weeds and grasses in pre- and post-emergence applications.

Enclosa herbicide will offer a wide application window to fit a variety of geographical herbicide programs and help farmers overcome challenging weather conditions.

Flexibility goes beyond application timing, as the new herbicide will be a strong tank-mix partner for products containing metribuzin or sulfentrazone in pre-emergence herbicide systems and glyphosate or glufosinate in post-emergence programs.

Enclosa herbicide also will be a complement to Enlist One herbicide, a benefit for farmers who plant Enlist E3 soybeans.

Additionally, the new soybean herbicide will come in an easy-to-use liquid premix, delivering convenience at the tank.

“Enclosa is a new novel ZC formulation. A AC formulation is when you take two dissimilar products and put them together,” Eric Scherder, national agronomy lead for herbicides and nitrogen stabilizers for Corteva, said at the annual Corteva Summer Media Day.

“Two dissimilar products don’t play well together, but in this case we’re taking Enversa, that encapsulated acetochlor using formulation science, and bringing in a liquid cloransulam which is something we don’t typically do in our industry.

“We have not seen a lot of liquid cloransulam, and that was one of our products for many, many years. The reason that’s important is growers do not want dry products anymore. Now, they’ll use dried AMS. They’ll use a few things. They want liquid formulations. It makes their jobs and life so much easier, and when they’re trying to work off the tender truck when out in the field, they want that liquid formulation.”

Mid-Tier Price

Budgets are tight and, with that in mind, Enclosa was developed to provide more versatility.

“We intentionally brought it in what I call that mid-tier price point,” Scherder said.

“We’ve got some really premium pre-emergence herbicides with six to eight weeks of residual. This product, we’re not looking for six to eight weeks. That four weeks of residual activity is what we’re trying to deliver very cost effectively for that customer.”
