Committee hears paraquat concerns, agency proposes permit‑based use through 2030 while EPA reviews volatilization data

The Senate Agriculture Committee discussed a House-passed bill that would restrict the use and sale of the herbicide paraquat amid new EPA scrutiny.

Steve Collier of the Vermont Agency of Agriculture told the committee paraquat is not widely used state‑wide but is important to some orchard operations. Collier summarized worker and bystander human‑health concerns and recent manufacturer actions: "Senta told us that they are going to stop supporting Koxone which is their version of paraquat at the end of this year," he said, and noted new EPA analysis about volatilization that could increase inhalation exposure.

Collier described a compromise in the House bill: allow paraquat use under an agency-issued written permit through Nov. 1, 2030 to cover the remainder of the growing seasons while the Agricultural Innovation Board evaluates acceptable substitutes. "There are other herbicides that can be used," he said, adding that the agency is cautious about broad bans because federal registration and scientific assessments are ongoing.

Why it matters: Paraquat is a highly toxic herbicide; agency staff said inhalation risk related to volatilization is prompting renewed attention. Committee members requested more testimony on prevalence and usage rates and indicated they will take testimony from farmers, health advocates and manufacturers at upcoming hearings.

Committee process: Staff said they will gather usage and dealer-reporting data for Friday's hearing and bring witnesses to address the risk profile and farm needs. The committee did not take action; members said they intend to weigh testimony before deciding whether to pursue restrictions, a phase‑out or a permit-based approach.
