🚨 URGENT: Industry-Wide Changes Effective 2025

AAPFCO's Uniform Beneficial Substances Bill creates the first nationwide framework for plant biostimulants. California implementation begins January 1, 2025, with other states following. Manufacturers must update labeling and claims to maintain compliance.

Revolutionary Regulatory Framework

The Association of American Plant Food Control Officials (AAPFCO) unanimously approved the landmark Uniform Beneficial Substances Bill in February 2024, fundamentally changing how plant biostimulants and beneficial substances are regulated across the United States.

EccoEdge Compliance has analyzed the complete regulatory framework to help manufacturers navigate these critical changes and maintain compliance across all 50 states.

Key Impact: For the first time, "plant biostimulant" claims are officially recognized and standardized across states, ending years of regulatory uncertainty and creating clear pathways for manufacturers.

Official AAPFCO Definitions

Beneficial Substance

"Any substance or compound (excluding nutrients and pesticides) that is scientifically shown to benefit plants, soil, or media."

Plant Biostimulant

"Substances, microorganisms, or mixtures that support a plant's natural nutrition processes independently of nutrient content — enhancing uptake, efficiency, stress tolerance, or growth."

Regulatory Significance: These definitions provide the first uniform, legally recognized framework for beneficial substances across all participating states, eliminating conflicting state interpretations.

Labeling Revolution: Old vs. New Format
