Chairman Subcommittee on Department Operations, MAR 25 1983 Research and Foreign Agriculture Committee on Agriculture House of Representatives Washington, D.C. 20515 Dear Mr. Chairman: As Dr. Benbrook of your staff requested, I am pleased to send you the enclosed Summary of Data Requirements for Registration of Pesticides and Date Established. This summary updates a data-requirements-over-time chart which appeared in a Congressional appropriations report several years ago. I believe the new summary will serve as a very useful reference source for persons interested in pesticide regulatory history. If I may be of further service in this regard, please let me know. Sincerely yours, Enclosure John A. Todhunter, Ph.D. and Toxic Substances (1) |
