HB 3405 designates poison hemlock and kudzu as noxious weeds in Oklahoma, requiring all landowners (public and private) to treat or remove these plants annually to prevent seeding. It mandates county entities and the Department of Transportation to manage infestations in rights-of-way, with landowners facing fines up to $1,000 per day for noncompliance. The bill requires the State Department of Agriculture to conduct annual surveys of infestations, report results to Oklahoma State University, and publish public notices in newspapers about landowner responsibilities. The law takes effect November 1, 2026, and includes provisions for landowners to request assistance with weed removal.
