The Pesticide Product Label System (PPLS), a database product developed by the U.S. Environmental Protection Agency (EPA), Office of Pesticide Programs (OPP), contains images of registered pesticide product labels and their amendments submitted by pesticide registrants and accepted by the OPP since 1971. The label images have been indexed by company, product, and date. The retrieval program allows the user to search by registration number only, which is a combination of company number and product number. Searches can be conducted based on partial numbers if the complete number is unknown. Search results are displayed in full screen format and single or multiple pages can be printed. If you do notknow the registration number, you may search the EPA Pesticide Product Information System through the Internet by using an online query developed by the California Department of Pesticide Regulation. The World Wide Web based online query allows you to search for product registration numbers by chemical, product name, and company. The addressfor this site is: http://www.cdpr.ca. gov./docs/epa/epamenu.htm Some label amendments address only portions of the label and may not represent the complete label. Review of all updates for a single productmay be necessary. The label images represent the product at the time thelabeling was accepted. The product may have been transferred to another company or canceled since the date the label was accepted and such status information is not reflected in this system. The quality of the images varies greatly as it is dependent on the quality of the label submitted to and accepted by OPP. Since the initial version of the PPLS on CD-ROM is the product of a conversion from images stored on microfiche, some oversized images are represented as two separate documents and will require retrieval of both to obtain the complete image. Regulations governing the labeling requirements of pesticide products are contained in Title 40, Code of Federal Regulations, Chapter1 (40 CFR Ch. 1).
