EPA’s response: No. Nowhere in EPA’s denial of the need for a more robust toxicological analysis is the problem more evident than in its refusal to require analyses of the so-called “inert ingredients” or “adjuvants” included in various formulations of pesticide products. The citizen petition [see more background] was followed by a lawsuit for the same purpose in 2022. Inerts and formulants are substances that enhance the distribution or adhesion of the active ingredient; adjuvants enhance the effectiveness of the active ingredient. These terms suggest that those chemicals have no effect on anything in the area where the pesticide is applied—a wildly inaccurate implication. At least as early as 1987, EPA had recognized that some inerts and adjuvants were “of toxicological concern,” yet it still requires very few toxicological tests of whole-formula pesticides or their purportedly inactive components. EPA responded to the petition as follows: “[T]he Agency appropriately assesses, as part of its review, the impacts to […]
