Although the U.S. Environmental Protection Agency reviews the research and approves pesticides for distribution to the public, the Wisconsin Department of Agriculture, Trade and Consumer Protection's Bureau of Agrichemical Management regulates pesticide manufacturing, use and distribution of EPA-approved pesticide products in Wisconsin. This sometimes involves special registrations that allow use of pesticides in ways not on the original label. You will find information here about how to become licensed to perform those functions, as well as information about specialized topics concerning pesticides.
