In 2015, the United States Court of Appeals for the 9th Circuit vacated U.S. EPA’s registration of the insecticide sulfoxaflor, finding that U.S. EPA lacked adequate data to ensure that its registration would not harm non-target species, and more specifically, bees. Following the 9th Circuit’s decision in September 2015, U.S. EPA reversed its position on two other pesticide registrations. In October 2015, U.S. EPA indicated that it planned to ban the agricultural use of chlorpyrifos notwithstanding U.S. EPA's previously stated intention to work with industry to mitigate the risks as opposed to an outright ban. In November 2015, U.S. EPA sought to voluntarily vacate its prior registration of Enlist Duo on the basis that U.S. EPA had obtained new data suggesting that the combined toxicity of its two ingredients (glyphosate and 2,4-D) was higher than originally believed. U.S. EPA was facing litigation in the 9th Circuit with respect to both of these pesticides which likely played a role in those decisions. In addition, U.S. EPA’s anticipated decision with respect to the reregistration of glyphosate has been delayed on multiple occasions and is now expected sometime in 2016.
These actions are all suggestive that U.S. EPA has elected to adopt a more stringent approach with respect to its risk reviews of pesticides under the Federal Insecticide, Fungicide and Rodentcide Act (FIFRA) and the Endangered Species Act (ESA). Such an approach is likely to result in significant delays in getting pesticide products registered and to the market. We will continue to follow these issues as we await U.S. EPA’s glyphosate reregistration decision which is likely to be the next significant U.S. EPA action in the FIFRA arena.
