The Environmental Protection Agency announced it will revoke approval of the Enlist Duo herbicide by Dow AgroSciences. The EPA claims it’s received new information on the herbicide and believes now it is more harmful than originally thought. Approved by the agency just over a year ago, Enlist Duo is a combination of glyphosate and 2,4-D. Environmental and Conservation groups say their fight against the “toxic cocktail” helped fuel the reversal by the EPA as the groups challenged the EPA’s alleged failure consider the herbicides impact on endangered plants and animals protected under the Endangered Species Act. The EPA had approved use of Enlist Duo in Illinois, Indiana, Iowa, Ohio, South Dakota, Wisconsin, Arkansas, Kansas, Louisiana, Minnesota, Missouri, Mississippi, Nebraska, Oklahoma and North Dakota, and had intended to approve it in additional areas in the near future.
