So... Are you looking for a source of objective, science-based information about pesticides - written for the non-expert? The EXTOXNET InfoBase may be for you!

The EXTOXNET InfoBase provides a variety of information about pesticides. Access the Pesticide Information Profiles (PIPs) for specific information on pesticides. Toxicology Information Briefs (TIBs) contain a discussion of certain concepts in toxicology and environmental chemistry. Other topic areas include: Toxicology Issues of Concern (TICs), Factsheets, News about Toxicology Issues, Newsletters, Resources for Toxicology Information, and Technical Information.

Information in these topic areas primarily has been developed by toxicologists and chemists within the Extension Service of the land-grant universities listed below. A major goal has been to develop unbiased information in a form understandable by the non-expert, and to make that information fully searchable and selectively retrievable.


EXTOXNET is a cooperative effort of University of California-Davis, Oregon State University,
Michigan State University, Cornell University, and the University of Idaho.
Primary files are maintained and archived at Oregon State University.
