A weed is a plant growing where you don't want it to grow. Weeds can cause allergies or rashes, injure or poison people or livestock, or reduce aesthetic or land values.
There are weeds that are such a problem that Minnesota has laws to control them. Minnesota law defines these noxious weeds as annual, biennial or perennial plants which are injurious to public health, the environment, public roads, livestock and other property.
Several weeds in Minnesota are considered noxious. You are required by law to control or eradicate the following prohibited plants, if they are on your property.
In addition, Minnesota law prohibits the import, sale or transport of Common and Glossy Buckthorn. Plus, some counties have additional weeds on their noxious lists. Most counties have management programs to control these weeds on farms, roadsides, utility rights of way, railroad tracks and ditch banks. Their objectives are prevention, control, or eradication.CONTROL METHODS
If you are not sure a plant is noxious, take the entire plant to a county agricultural inspector for identification. For more information in Minnesota, call the Farm Information Line at 800-232-9077, or visit the Minnesota Department of Agriculture.
