H.R. 3783: Plant Biostimulant Act of 2025

This bill, known as the Plant Biostimulant Act of 2025, aims to amend existing regulations under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) concerning the definition and regulation of plant biostimulants. Here are the key provisions of the bill:

Definition of Plant Biostimulants

The bill proposes the following changes to the definitions related to plant biostimulants:

• New Definition: A plant biostimulant is defined as a substance, microorganism, or mixture thereof that, when applied, supports a plant's natural processes, enhancing:
1. Nutrient availability, uptake, or use efficiency;
2. Tolerance to abiotic (non-living) stress;
3. Overall growth, development, quality, or yield of the plant.
• Exclusions: The bill also clarifies that plant biostimulants do not include certain materials that act as plant nutrients or soil amendments.

Regulatory Changes

Following the enactment of this legislation, the Environmental Protection Agency (EPA) is required to revise the regulations regarding plant biostimulants within 120 days in order to align with the updated definitions provided in the bill.

Soil Health Study

The bill mandates that the Secretary of Agriculture conduct a study evaluating various types of plant biostimulants and their practices. The research should focus on:

• Increasing organic matter in soils.
• Reducing the volatilization of atmospheric compounds.
• Promoting effective nutrient management.
• Limiting the runoff or leaching of harmful substances into water sources.
• Restoring beneficial microbial activity or nutrients in soils.
• Aiding in carbon sequestration and enhancing climate-related benefits.
• Supporting sustainable agricultural practices through innovative strategies.

A report detailing the results of this study must be made publicly available within two years of the funds being allocated for the study.

Impact on Regulatory Framework

By providing a clear definition of plant biostimulants, this bill aims to streamline the regulatory process for these substances, potentially allowing for more innovative and effective use of agricultural products that can improve farming practices and sustainability.
