Corteva to Bring Enclosa Herbicide to U.S. Soybean Farmers

By Corteva|30 July 2026

Corteva continues to expand farmer and retailer access to new soybean herbicide options with the launch of Enclosa herbicide. The new herbicide will provide the first-ever combination of a proprietary encapsulated acetochlor (Group 15) and cloransulam (Group 2) to deliver exceptional weed control with up to four weeks of residual activity. Enclosa herbicide has been granted approval from the U.S. Environmental Protection Agency (EPA) and is now in the process of receiving state approvals.

“Corteva is at the forefront of soybean herbicide innovation,” said Drake Robards, Portfolio Marketing Lead, Soybean Herbicides, Corteva. “In the past few years, we’ve expanded our soybean herbicide portfolio to better meet the needs of farmers, maximize yield potential and optimize management decisions. The launch of Enclosa herbicide is the latest advancement that will give farmers an additional option for flexible and convenient control.”

With the launch of Enversa herbicide in 2025, 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.

“Multiple modes of action are more important than ever to effectively manage weeds and mitigate the spread of herbicide resistance,” Robards said. “We’ve seen the power encapsulated acetochlor brings to the tank. The addition of cloransulam will enable farmers to tackle tough weeds and reduce the threat of resistance.”

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 an excellent 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.
