  1. Biostimulants:A State Fertilizer Regulatory Program Perspective BPIA ~ Portland March 13, 2019 Matt Haynes Oregon Department of Agriculture

  2. Framing the Question: Fertilizer Regulation • No Federal / national regulatory program • Regulated by individual states • Regulations and requirements vary between states

  3. The Role of the Association of American Plant Food Control Officials (AAPFCO) • Promote uniformity through consensus • Encourages uniform: • Definitions • Model bills for legislation • Labels and labeling • Inspection methods • Sampling and analysis

  4. The Role of AAPFCO • Not regulatory • Participation is voluntary • Conformity trumped by state laws • Definitions - one of the most commonly used, and useful, functions • The term “biostimulant” does not appear as a term or definition in the current Official Publication No. 72

  5. Regulatory Challenges • Fair and equitable regulation requires accurate and complete definitions • Validated analytical methods are needed to verify label guarantees

  6. The Definition of Biostimulant Depends on Whom You Ask

  7. Relevant EPA Term Plant Regulator or Plant Growth Regulator (PGR) “A plant growth regulator, through physiological action, is intended to accelerate or retard growth, or alter plant behavior or the produce of the plant.” “Whether a product is considered to be a plant growth regulator depends on whether the plant response or mode of action being claimed would go beyond what would be expected from simple nutrition.” EPA Label Review Manual (2014), page 2-6

  8. Biostimulants? • Humic substances • Bacteria and Fungi (VOCs) • Chemical elements (Si) • Inorganic salts, including phosphite • Seaweed extracts • Chitin and chitosan derivatives • Antitranspirants • Free amino acids • Salicylic Acid

  9. Questions for Regulators Does the product work and how? • Rates • Lab vs. field data • Limiting conditions • Pesticidal vs. non-pesticidal mode(s) of action When product is sampled in the marketplace, how can guarantees be verified?

  10. Status of Biostimulant as a Term • Inconsistent use of the term • Action(s) poorly understood • Not an AAPFCO-defined term or definition • Most states will not accept it in labeling • Most state fertilizer programs will accept the term biostimulant if it is used as part of the name of an EPA- registered product • Section 9201 in the current farm bill does not provide for carte blanche use of the term
