Enlist Duo OK'd for use on three crops in 34 states

Corn, soybean and cotton growers in 34 states will be allowed to use Enlist Duo under a new decision issued by EPA.

The agency had to reconsider its 2014 decision to approve use of the herbicide because of questions about the synergistic effects of 2,4-D and glyphosate, the two active ingredients in the product.

EPA initially allowed use of Enlist Duo on corn and soybeans in six states and then expanded that number to 15. Now, based on new data submitted by manufacturer Dow AgroSciences, EPA has reaffirmed its original decision on the safety of the product and added approval for use in another 19 states, not just for genetically engineered corn and soybeans, but for GE cotton, as well.

“The pesticide meets the safety standard for the public, agricultural workers, and non-target plants and animal species, including a ‘no effects' determination for species listed as threatened or endangered under the Endangered Species Act,” EPA said.
