Data required for pesticide registration submission must be collected using standardized methods set forth by the EPA or the Organization for Economic Co-operation and Development (OECD). Each required data category has an accompanying series of necessary tests. The various series identify and detail the data required for registration, as well as the test methodology. Additional EPA-accepted standardized test methods can be found on the OECD webpage. All testing must align with OECD Good Laboratory Practice.

The tests in this table represent required registration data for aquatic conventional pesticides. Information collected from 40 CFR 158.

¹ CR represents "Conditional Requirement." All other tests are required unless otherwise noted. This table does not cover all CR tests but includes those likely to be required for the registration of an algaecide. A full list of CR tests can be found in 40 CFR 158.

Collection of the required pesticide registration data may require field trials. Unregistered pesticides may be applicable for an Experimental Use Permit (EUP). Although the complete set of registration data may not be available at the time of an EUP request, most studies and resulting data must have been collected before the EPA will grant an EUP. An EUP must also be approved by the state in which the experimental use is to take place. To determine the policy of an individual state, use the external link to the National Pesticide Information Center or the internal link to the US Regulatory Map.

• Navigate to the EPA webpage for a list of required data Test Guidelines
• If your proposed product is substantially similar to another EPA-registered product, you may be able to cite data from existing studies.
• If citing another company's data, you must first determine whether you need to pay or get authorization from the data owner to use it. More can be found in the Pesticide Registration Manual: Ch. 10 - Data Compensation Requirements.
• Determine the registration fee(s) and review timeframe for your product:
  • The Pesticide Registration Improvement Act (PRIA, aka PRIA 5) requires the submission of fees associated with EPA assessments of pesticide data.
  • Use the PRIA Fee Determination Decision Tree to find the fees and review timeline associated with your product.
  • If you are a small business, academic institution, non-profit, or state/federal office, you may qualify for a fee waiver.
• Suggestions to Registrants on Providing Benefits Information for New Conventional Pesticide Registrations and New Outdoor Uses of Conventional Pesticides
• Schedule a pre-registration meeting with the Office of Pesticide Products Registration Division. See contact information below.

This information was collected from 40 CFR 158 or the EPA's Test Guidelines for Pesticides and Toxic Substances unless otherwise noted.

When granting pesticide registrations, EPA must comply with section 7(a)(2) of the Endangered Species Act (ESA) to protect federally threatened or endangered (listed) species. Before registering any new conventional active ingredient, EPA will evaluate the potential effects of the active ingredient on federally threatened or endangered species and their designated critical habitats, and initiate ESA consultation with the U.S. Fish and Wildlife Service and the National Marine Fisheries Service, as appropriate.

As part of its analysis, EPA will consider the likelihood that product registration may jeopardize the continued existence of listed species or adversely modify their designated critical habitat. If EPA predicts that jeopardy or adverse modification is likely, the Agency will only make a registration decision after requiring registrants to implement mitigation measures. Applicants should consider proposing mitigations or use patterns that eliminate or reduce potential impacts to listed species in their applications for new active ingredients.

For more information, contact the Registration Division Ombudsman or the appropriate Product Team prior to submitting an application. See the Progress Toward Protections for Federally Listed Species webpage and the ESA Policy for New Active Ingredients: Q&A (PDF) to learn more.
