Key Points

  • Creates a single, clear federal definition for “plant biostimulants,” like products added to seeds, soil, or plants to help natural plant processes.
  • Says plant biostimulants (including biological ones and certain bio-like synthetic ones) are not treated as “plant regulators” under pesticide law.
  • Requires the Environmental Protection Agency to update its rules within 120 days after the bill becomes law so regulations match the new definitions.
  • Directs the Agriculture Department to study which biostimulant types and farming practices best improve soil health and cut nutrient losses into water.
  • Requires a public report to Congress within 2 years after money is first provided for the study.
