Proposed Rules On Disclosure of Inert Pesticide Ingredients

The U.S. Environmental Protection Agency is requesting public comment on options for disclosing inert ingredients in pesticides. In this anticipated rulemaking, EPA is seeking ideas for greater disclosure of inert ingredient identities. Inert ingredients are part of the end use product formulation and are not active ingredients. Pesticide manufacturers usually disclose their inert ingredients only to EPA. Currently, EPA evaluates the safety of all ingredients in a product’s formulation when determining whether the pesticide should be registered.

On October 1, 2009, EPA responded to two petitions to designate more than 350 inert pesticide ingredients as hazardous. The petitioners asked EPA to require that these ingredients be identified on the labels of products that include them in their formulations.

EPA is accepting comments on the advance notice of proposed rulemaking for 60 days after it has been published in the Federal Register.
