Pesticide Registration

Pesticide Use Sites and Major Use Patterns

The Pesticide Use Site Index will help a company (or other applicant) identify which data requirements are needed to register a pesticide product. The documents on this page provide pesticide use site information sorted by the site term or by the crop group (the first two files) and then the main use patterns, such as "aquatic food use." More information about the pesticide use site index.

You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
