Research Authorizations and Experimental Use Permits
A Research Authorization (RA) is a permit required for experimental pesticide applications taking place in the state.
Effective January 1, 2016, DPR made changes to Title 3, California Code of Regulations (3 CCR) sections 6260, 6262, 6264, and 6266 pertaining to research authorizations. In accordance with these changes, DPR has redesigned the RA application and use report forms. The forms and instructions are linked below.
Requests for authorization of research trials beginning on or after January 1, 2016, must be submitted to DPR on the new RA application form PR-REG-027a (Est. 4/15) and, if needed, form PR-REG-027b (Est. 4/15).
To apply for a Research Authorization, complete the appropriate form(s) and submit to DPR by e-mail at RAs@cdpr.ca.gov or by postal mail at:
Research Authorization Coordinator
Department of Pesticide Regulation
Pesticide Registration Branch
P.O. Box 4015
Sacramento, CA 95812
Consult the evaluation staff listed as the contact at the bottom of this page for any questions regarding the forms or the research authorization program.
Revised RA Notification Requirements
In addition to the new forms, the Research Authorization regulation changes require that beginning January 1, 2016, researchers provide the CAC with a copy of the approved research authorization and a notice of the intended pesticide application at least 72 hours prior to applying a pesticide requiring a research authorization, unless the CAC determines that a shorter time period is adequate to evaluate the intended pesticide application. The notice of intended application must also include the location of each trial on a plot map and a map or aerial photograph designating the location and identity of sensitive sites that could be adversely impacted by the pesticide application.
The notice of intended application provided to the CAC must also be submitted to DPR at the same time it is provided to the CAC. The notice may be submitted by e-mail to RA_NOI@cdpr.ca.gov.

Note: Any Research Authorization application that does not include the active ingredient of the product due to status as trade secret information shall be accompanied by a signed request for exemption from disclosure. A letter such as the sample letter linked below may be used. The request may be submitted separately from the RA application if done so in a timely manner. Failure to do so may result in the application being denied.
Experimental Use Permits
U.S. EPA issues experimental use permits (EUPs) that allow researchers to conduct field testing of an unregistered pesticide product, or unregistered use of a pesticide product, to gather additional data. In some cases, researchers may choose to register their federal EUP with DPR on a conditional basis instead of applying for an RA.
