MI HB4896

Restructures the definition of "noxious weeds" in Michigan law to list specific plant species individually (Canada thistle, dodders, mustards, wild carrot, bindweed, perennial sowthistle, hoary alyssum, giant hogweed, ragweed, poison ivy, and poison sumac) with their scientific names in italics.

Replaces vague references to plant genera with precise scientific nomenclature (e.g., changing "species of Cuscuta" to "the genus Cuscuta").

Adds an exemption prohibiting milkweed (any species of the genus Asclepias) from being classified as a noxious or exotic weed, even if local governments consider it a common nuisance.

Clarifies that local governments (counties, cities, townships, or villages) may designate other plants as noxious weeds only if they meet the statutory criteria and are regarded as common nuisances.
