Plant Biostimulant Act of 2025
Sponsored By: Representative Rep. Panetta, Jimmy [D-CA-19]
Introduced
Summary
Clear legal definitions separating plant biostimulants from plant regulators. This bill would revise FIFRA terms to distinguish biostimulants from plant regulators, require the EPA to update rules, and direct USDA to study biostimulant effects on soil health.
Show full summary
- Farmers and growers would get clearer rules because the bill defines “Plant Biostimulant” and narrows the “Plant Regulator” definition by excluding biologically derived biostimulants. This clarifies which products fall under pesticide rules.
- Manufacturers and product developers would face regulatory change because the EPA would have to revise regulations within 120 days after enactment to match the new definitions. This alters how products are reviewed and regulated.
- Researchers and conservation programs would gain new evidence because the Secretary of Agriculture would study which biostimulants and practices best boost soil health and reduce nutrient loss, then publicly report results to congressional agriculture committees within two years after funds are available.

Bill Overview
Analyzed Economic Effects
3 provisions identified: 2 benefits, 0 costs, 1 mixed.
New rules for biostimulant products
This bill would change key definitions in the pesticide law. It would define “plant biostimulant,” “nutritional chemical,” and “vitamin hormone product.” It would also narrow what counts as a “plant regulator,” excluding many nutrient products and some biostimulants of biological origin (and close synthetic copies). A plant biostimulant would be one that helps plants’ natural processes, like nutrient use or stress tolerance, when applied to seeds, plants, soil, or the root zone. If passed, this could shift which products need pesticide-style oversight and labels.
USDA study on farm soil health
This bill would direct USDA to study which plant biostimulants and practices work best. The study would look at goals like raising soil organic matter, cutting nutrient runoff, and boosting carbon storage. USDA would publish the results and send a report to Congress within 2 years after funds first become available. Farmers could use the findings to choose products and practices with better results.
EPA to update rules in 120 days
This bill would require EPA to revise its regulations to match the new definitions. EPA would have 120 days after enactment to finish the updates. This would give manufacturers and farmers quicker clarity on how to comply.
