The Plant Biostimulant Act of 2025 aims to clarify and standardize the definition of plant biostimulants within the framework of the Federal Insecticide, Fungicide, and Rodenticide Act. The main goal is to ensure that these substances, which support plant growth and health, are recognized and regulated appropriately. Key provisions of the Act include a new definition of plant biostimulants, which are described as substances or microorganisms that enhance a plant's natural processes without relying solely on their nutrient content.
