Spotted knapweed and a seedhead weevil

Minnesota Noxious Weed Law

Minnesota's Noxious Weed Law requires landowners to manage their property for noxious weeds. The list of noxious weeds can be found here.

There are three levels of control:

Eradicate List: these species must be killed both above ground (foliage) and below ground (roots). This is the highest level of control.
Control List: these species must be controlled to prevent the maturation and spread of propagating parts (e.g. seeds, roots).
Restricted List: these species may not be sold, intentionally transported, or planted in Minnesota.

Each county also has the ability to add species to these lists on a case-by-case basis.

A guide to removing noxious weeds can be found here: Guide to Removal and Disposal of Noxious Weeds in Minnesota
