The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 7 requires that production of pesticides, active ingredients or devices be conducted in a registered pesticide-producing or device-producing establishment ("production" includes formulation, packaging, repackaging, labeling and relabeling). Production in an unregistered establishment is a violation of the law. Information on pesticide establishments is tracked through the Section Seven Tracking System.  Additional limited information on establishments is available online here.
