Federal Court to EPA: No, You Can’t Approve This Pesticide That Kills Bees

On Thursday, a federal appeals court struck down the Environmental Protection Agency's approval of a pesticide called sulfoxaflor. Marketed by agrichemical giant Dow AgroSciences, sulfoxaflor belongs to a class of pesticides called neonicotinoids, which have been implicated by a growing weight of evidence in the global crisis in bee health. In a blunt opinion, the court cited the “precariousness of bee populations” and “flawed and limited data” submitted by Dow on the pesticide's effects on beleaguered pollinating insects.

Before winning approval for sulfoxaflor back in 2013, the company hyped the product to investors, declaring that it “addresses [a] $2 billion market need currently unmet by biotech solutions,” particularly for cotton and rice.

US beekeepers were less enthusiastic—a group of national beekeeping organizations, along with the National Honey Bee Advisory Board, quickly sued the EPA to withdraw its registration of sulfoxaflor, claiming that the EPA itself had found sulfoxaflor to be “highly toxic to honey bees, and other insect pollinators.”
