Note: Products in regular type are those registered with EPA as of June 3, 2000. Asterisks indicate pet products known to form the basis for EPA’s risk assessment for that chemical. Dichlorvos, diazinon and malathion risk assessments did not list particular products. Italicized products are those for which, subsequent to the risk assessment, manufacturers now indicate they will no longer maintain registration of the product. In most, if not all such cases, however, the products remain in use at the time this report was prepared. |
