On Friday, March 8, 2019, the Pesticide Registration Improvement Extension Act of 2018 (PRIA 4) was signed into law.  This new legislation reauthorizes PRIA for five years through fiscal year 2023, and updates the fee collection provisions of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).  This legislation also reflects changes to some registration fee categories and timeframes, and preserves some fee waivers for small businesses.  PRIA 4 is effective as of the date of signature (March 8, 2019).
