EPA: Data Requirements for Pesticide Registration

EPA developed guidance for assessors on determining data needs for neurotoxicity, subchronic inhalation, dermal and immunotoxicity studies using the weight-of-the-evidence methods. This guidance will assist registrants in developing data waiver requests. The guidance on immunotoxicity study needs was based in part on Retrospective Analysis of the Immunotoxicity Study (OCSPP Test Guideline No. 870.7800).
