Plant Biostimulant Act of 2023

S 802, the Plant Biostimulant Act of 2023, removes plant biostimulants from regulation under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). It defines plant biostimulants as substances or microorganisms that improve plant growth and nutrient efficiency without relying on their nutrient content, excluding them from FIFRA oversight. The bill requires the EPA to revise regulations within 120 days to reflect this exclusion and mandates a soil health study by the Secretary of Agriculture. This study will evaluate how biostimulants affect soil health metrics like organic matter, nutrient runoff, and carbon sequestration, with a public report due within one year. The bill directly affects producers and users of biostimulant products in agriculture.
