EPA Revokes Approval of 'Synergistic' Pesticide Enlist Duo Due to Butterfly Deaths

The Environmental Protection Agency has decided to revoke its approval of Dow AgroSciences’ product Enlist Duo after determining that the product is “likely significantly more harmful than initially believed,” according to a press release published by the Center for Biological Diversity on Wednesday. Specifically, the chemical appears to be linked to monarch butterfly deaths.

EPA appealed to the courts on Tuesday to reverse their original decision, citing a discovery of new information as a reason behind this change.

When EPA originally approved the product, Dow had argued that the combination was no more toxic than the two chemicals separately. However, when applying for a patent, NPR reported, Dow told the U.S. Patent and Trademark Office that the chemical combination would offer “synergistic herbicide weed control,” something that environmental activists had cited as a possible problem when the product was originally approved, including the over 200,000 people who signed a petition to ask the company to stop selling the product. This is also a distinctly new effect connected to the combination as opposed to the two chemicals separately.

“E.P.A. can no longer be confident that Enlist Duo will not cause risks of concern to nontarget organisms, including those listed as endangered, when used according to the approved label,” the agency said in its filing to he United States Court of Appeals for the Ninth Circuit in San Francisco, reports the “New York Times.” EPA originally approved the herbicide in November 2014.

Enlist Duo is a mixture of glyphosate, the active ingredient in Roundup, and 4-D. The combination of the two is intended to be used on GMO corn and soybean strains that have been genetically engineered to tolerate it. Glyphosate has also been cited as the chief cause of the decline of the monarch butterflies, according to a press release from the Natural Resources Defense Council.

“Removing this dangerous chemical from the market is a key step in protecting sensitive native plants and monarch butterflies, which have been further threatened by its impact on milkweed, the plant they need to survive,” said Sylvia Fallon, Senior Scientist at the NRDC. “We are delighted by this news, but also troubled that EPA overlooked this information initially.”

In a press release published Wednesday, Dow claimed that Enlist Duo should still reach markets for the 2016 growing season.
