EPA has produced a vast collection of science-related documents to support pesticide registration decisions. Below you will find a subset of documents that, generally, have been requested by the public through the Freedom of Information Act (FOIA) process. Each of these documents has been reviewed to ensure that any proprietary information is not included.

If you wish to obtain a document that is not currently posted, you may do so by filing a FOIA request.
