Plant Biostimulant Act of 2025
To amend the Federal Insecticide, Fungicide, and Rodenticide Act to provide for a consistent definition for plant biostimulants.
Summary
This bill amends federal agriculture law to establish a consistent definition for plant biostimulants—substances or microorganisms applied to plants or soil that support natural growth processes and improve nutrient uptake, stress tolerance, and yield. The bill distinguishes plant biostimulants from plant regulators, with exemptions for products of biological origin or synthetically derived but functionally identical versions of biological compounds. The EPA must update its regulations within 120 days to implement these definitions. The bill also directs the Department of Agriculture to conduct a two-year study on best practices using plant biostimulants to improve soil health, nutrient management, carbon sequestration, and agricultural sustainability.

IN THE HOUSE OF REPRESENTATIVES
June 5, 2025
Mr. Panetta (for himself and Mr. Baird) introduced the following bill; which was referred to the Committee on Agriculture
A BILL
To amend the Federal Insecticide, Fungicide, and Rodenticide Act to provide for a consistent definition for plant biostimulants.
Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled,
SECTION 1. SHORT TITLE.
This Act may be cited as the “Plant Biostimulant Act of 2025”.
SEC. 2. DEFINING PLANT BIOSTIMULANTS.
(a) In General.—Section 2 of the Federal Insecticide, Fungicide, and Rodenticide Act (7 U.S.C. 136) is amended—
(1) by striking subsection (v) and inserting the following:
“(v) Plant Regulator.—
“(1) In general.—The term ‘plant regulator’ means any substance or mixture of substances intended, through physiological action, for accelerating or retarding the rate of growth or rate of maturation, or for otherwise altering the behavior, of plants or the produce thereof.
“(2) Exclusions.—The term ‘plant regulator’ does not include—
“(A) substances to the extent that they are intended as plant nutrients, trace elements, nutritional chemicals, plant inoculants, soil amendments, or vitamin hormone products; or
“(B) plant biostimulants that—
“(i) are of biological origin; or
“(ii) include chemical compounds that are synthetically derived, but are structurally similar and functionally identical to, substances of biological origin.”;
(2) in subsection (hh)—
(A) in paragraph (2), by striking “or” at the end;
(B) in paragraph (3)—
(i) in the matter preceding subparagraph
(A), by striking “substances.” and inserting “substances”; and
(ii) in subparagraph (B)—
(I) by inserting “, or” after “volatilization”; and
(II) by striking the period at the end and inserting a semicolon; and
(C) by inserting before the undesignated matter following paragraph (3) the following:
“(4) a plant biostimulant; or
“(5) a nutritional chemical.”; and
(3) by adding at the end the following: “(pp) Plant Biostimulant.—The term ‘plant biostimulant’ means a substance, microorganism, or mixture thereof, that, when applied to seeds, plants, the rhizosphere, soil, or other growth media, act to support a plant’s natural processes independently of the nutrient content of that substance, microorganism, or mixture thereof, and that thereby improves—
“(1) nutrient availability, uptake, or use efficiency;
“(2) tolerance to abiotic stress; and
“(3) consequent growth, development, quality, or yield. “(qq) Nutritional Chemical.—The term ‘nutritional chemical’—
“(1) means any substance or mixture of substances that interacts with plant nutrients in a manner which improves nutrient availability or aids the plant in acquiring or utilizing plant nutrients; and
“(2) includes some plant biostimulants. “(rr) Vitamin Hormone Product.—The term ‘vitamin hormone product’ means a product consisting of a mixture of plant hormones, plant nutrients, inoculants, or soil amendments.”.
(b) Regulations.—Not later than 120 days after the date of the enactment of this Act, the Administrator of Environmental Protection Agency shall revise the regulations under subchapter E of chapter I of title 40, Code of Federal Regulations (as in effect on the date of the enactment of this Act) to carry out the amendments made by subsection
(a).
SEC. 3. SOIL HEALTH STUDY.
(a) Study.—The Secretary of Agriculture (referred to in this section as the “Secretary”) shall conduct a study to assess the types of, and practices using, plant biostimulants (as defined in section 2 of the Federal Insecticide, Fungicide, and Rodenticide Act (7 U.S.C.
136), as added by section 2 of this Act) that best achieve the following:
(1) Increasing organic matter content.
(2) Reducing atmospheric volatilization.
(3) Promotion of nutrient management practices.
(4) Limiting or eliminating runoff or leaching of soil or nutrients such as phosphorus and nitrogen into groundwater or other water sources.
(5) Restoring beneficial bioactivity or healthy nutrients to the soil.
(6) Aiding in carbon sequestration, nutrient use efficiency, and other climate-related benefits.
(7) Supporting innovative approaches to improving agricultural sustainability, including the adoption of performance-based outcome standards and criteria.
(b) Report.—Not later than 2 years after the date on which funds are first made available to conduct the study under subsection (a), the Secretary shall make publicly available, and submit to the Committee on Agriculture of the House of Representatives and the Committee on Agriculture, Nutrition, and Forestry of the Senate, a report that describes the results of the study. <all>
