EPA Rejects Petition Seeking Review of Complete Ingredients in Pesticide Products

(Beyond Pesticides, October 16, 2023) After six years, the Environmental Protection Agency (EPA) finally responded to a citizen petition requesting that the agency evaluate complete formulations of pesticide products, not just the ingredients the manufacturer claims attack the target pest (so-called “active” ingredients). 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 […]

“Inert” Pesticide Ingredients and Failure to Regulate Raise Dangers for All U.S. Residents

(Beyond Pesticides, August 9, 2022) The most widely used pesticide chemicals in the United States are not listed on product labels, yet pose widespread environmental and public health hazards, according to commentary published this month in Environmental Health Perspectives by two veteran researchers. At issue are adjuvants and so-called “inert” (or “other”) ingredients, chemicals that are added to formulated pesticide products, but do not undergo the same safety reviews as the active ingredient in pesticide products. This donut hole of regulation has permitted, as the commentary shows, millions of pounds of chemicals to be applied in California and throughout the country without proper scientific evaluation of their human health or ecological impact. Researchers first draw a distinction between adjuvant products and inert ingredients in pesticide products. Adjuvants are materials specifically designed to improve the performance of a pesticide spray and are sold separately from formulated pesticide products. Adjuvants are “tank mixed” with a pesticide prior its application. Inert ingredients are any ingredient within a formulated pesticide product that is not designed to prevent, destroy, or repel a pest. Adjuvants and inert ingredients can be the same material – the difference lies in when they are added to a formulated pesticide […]
