Senate Agriculture Committee reviews H.484 to standardize 'beneficial substances' labeling

The Senate Agriculture Committee on April 3 heard testimony on H.484, an act to amend Chapter 28 to update Vermont’s registration and labeling requirements for so‑called “beneficial substances,” agency officials said.

Agency witnesses told the committee the bill would align Vermont’s definitions and labeling rules for beneficial substances with national model language used by other states and by industry groups, giving regulators clearer authority to remove registrations if products are found to be adulterated or not effective for the claims on their labels.

Stephanie Smith, deputy director of the Public Health and Agriculture Resource Management Division at the Agency of Agriculture, Food and Markets, said the division oversees registration and label review for fertilizer, soil amendments and related products and enforces guaranteed analysis requirements. "The division of public health and ag resource management is responsible for agricultural inputs, preregistered weed seed, fertilizer, and beneficial substance products within our division," Smith said. She added the programs are consumer‑protection efforts and that the agency reviews labels and guaranteed analyses as part of registration.

Smith and a second agency witness told the committee the bill is intended to make Vermont law consistent with uniform beneficial‑substance language that some states already use. Smith listed California, Minnesota, Utah, Oregon, Oklahoma, North Dakota, Mississippi and Iowa as states that have adopted or are considering similar measures. She also said industry and professional groups—identified in testimony as the Fertilizer Institute (TFI) and the Association of American Plant Food Control Officials (APFCO/APCO)—are developing methods and lists of ingredients and test methods that states can rely on.

Committee members pressed agency staff about how claims would be verified in practice. Smith said efficacy claims are registered against the label and that the agency can withdraw a product’s registration if evidence from other states or laboratory testing shows a product is ineffective or adulterated. "It has to be efficacious based on the claim, and we register it for the claim," Smith said.

Agency witnesses described limits in laboratory capacity for testing the broad universe of beneficial‑substance materials. The agency’s laboratory currently performs routine nutrient analyses for fertilizers but does not have the resources to test the many different biological and chemical materials marketed as beneficial substances. Staff said Vermont often relies on other state labs, university research, or work produced by national associations to inform enforcement and registration decisions.

Supporters framed the bill as an efficiency and consumer‑protection measure: if state laws and definitions are consistent across jurisdictions, manufacturers can submit one label package for multiple states and regulators will have common standards to evaluate ingredient lists and efficacy claims. Agency staff told the committee the bill would give the state clear authority to cancel registrations if outside testing or association reviews demonstrate problems.

The committee did not take a vote on H.484 during the hearing.

The testimony also noted how existing feed and fertilizer statutes interact with beneficial‑substance definitions: staff said some inoculants used on harvested feed may fall under feed‑supplement rules rather than the plant/soil beneficial‑substance definitions, and they agreed to follow up with additional clarifications if the committee requests them.
