HB3405 amends Oklahoma’s noxious weed law to add poison hemlock and kudzu to the list of designated noxious weeds, alongside existing thistles. The bill declares these plants to be public nuisances statewide and requires landowners to treat, control, or eradicate them each year so they do not go to seed. It also places responsibility on the Department of Transportation, county commissioners, and other public or private entities that maintain rights-of-way to remove infestations within their jurisdictions.
The bill gives the State Department of Agriculture authority to inspect infestations after a written complaint and determine the most appropriate treatment or eradication method. It also directs the State Board of Agriculture to adopt rules on infestation categories, include poison hemlock and kudzu as prohibited noxious weeds and weed seed, conduct annual statewide surveys, and provide public notice through newspapers about the duty to control these weeds and the availability of assistance. The measure removes the existing fine language for failure to control the listed weeds, while preserving the possibility of legal action requiring treatment, control, or eradication.
If enacted, HB3405 would amend 2 O.S. 2021, Section 3-220, expanding the state’s noxious weed enforcement framework to cover poison hemlock and kudzu. It would affect landowners, public agencies, and any entity responsible for rights-of-way, and it would increase the role of the Department of Agriculture and Oklahoma State University extension agents in inspection and response. The bill is set to take effect November 1, 2026.
The overall sentiment appears strongly supportive and largely noncontroversial. The bill passed the House Agriculture Committee and the House Energy and Natural Resources Oversight Committee unanimously, and it passed the House floor by a wide margin. The available committee transcript is minimal, but the recorded votes suggest broad agreement that the plants pose a statewide nuisance and should be subject to control requirements.
The main point of distinction in the bill is the shift from a monetary penalty to an enforcement model centered on inspection, notice, and legal action rather than a direct fine. Any contention would likely focus on the burden placed on landowners and rights-of-way managers, as well as the practical costs of eradication and compliance, but the legislative record provided does not show significant opposition.
HB3405 would amend Oklahoma’s noxious weed statute, 2 O.S. 2021, Section 3-220, to add poison hemlock and kudzu to the list of designated noxious weeds and prohibited weed seed. It expands duties for landowners and rights-of-way holders to control or eradicate these plants, authorizes Agriculture Department inspections and OSU extension evaluations, and requires the State Board of Agriculture to adopt implementing rules, conduct surveys, and publish public notices. The bill also removes the existing fine provision for certain violations, shifting enforcement toward administrative action and court-ordered compliance.
The bill appears to have broad bipartisan and committee support. It advanced unanimously in both committee votes shown and passed the House with a substantial margin, indicating general agreement that poison hemlock and kudzu are harmful invasive species warranting state action. The limited transcript does not reflect substantive debate, and the available voting history suggests the measure was viewed favorably and as a practical agriculture/public nuisance bill.
The principal policy issue is enforcement: HB3405 removes the explicit fine for failure to control the weeds while still allowing legal action to compel treatment, control, or eradication. That change may reduce direct financial penalties but could also raise questions about how aggressively the state will enforce compliance and who bears the cost of eradication. Potential concerns for landowners, counties, and other rights-of-way managers include the expense and operational burden of ongoing weed control, but the recorded legislative action shows little visible opposition.
