S. 1907: Plant Biostimulant Act of 2025

This bill, known as the Plant Biostimulant Act of 2025, aims to amend the Federal Insecticide, Fungicide, and Rodenticide Act to establish a clear and consistent definition for "plant biostimulants." Here are the main components of the bill:

Definition of Plant Biostimulants

The bill introduces a specific definition for plant biostimulants, which will be defined as substances, microorganisms, or mixtures that, when applied to plants or soil, enhance a plant's natural processes independently of their nutrient content. This enhancement can improve:

• Nutrient availability, uptake, or use efficiency
• Tolerance to abiotic stress (like drought or salinity)
• Growth, development, quality, or yield of the plants

Moreover, the bill excludes certain products from being classified as plant regulators, such as plant nutrients and substances intended specifically for that purpose.

Regulatory Changes

The bill mandates that within 120 days of its enactment, the Environmental Protection Agency (EPA) must revise current regulations to reflect the new definitions and clarifications regarding plant biostimulants. This update aims to provide guidelines and ensure compliance with the revised definitions.

Soil Health Study

The bill also directs the Secretary of Agriculture to conduct a study assessing the types of plant biostimulants that can effectively achieve specific agricultural and environmental goals. Some key objectives of the study include:

• Increasing organic matter in soil
• Reducing nutrient loss to the atmosphere
• Promoting better nutrient management practices
• Limiting runoff or leaching of nutrients into water sources
• Restoring beneficial bioactivity and nutrients in soil
• Aiding in carbon sequestration and other climate-related benefits
• Supporting innovative sustainability approaches in agriculture

A report detailing the study's findings is required to be made publicly available within two years after funding becomes available.

Impact on Legislation

This legislation seeks to provide clear guidelines on the use of plant biostimulants, which could influence agricultural practices and products in the United States, potentially leading to improved crop yield and environmental sustainability.

Relevant Companies

• AOS - A manufacturer of water treatment and specialty chemical products, which may be impacted by new regulations on biostimulants and nutrients applied to water sources.
• DE - A leading agricultural equipment company that might experience shifts in demand for biostimulant-related equipment and application technologies as the market evolves.
• CYX - Develops agricultural products, including biostimulants; this company may see regulatory changes impact product development and marketing strategies.
