Top 10 Noxious Weed List in Minnesota

A noxious weed, according to Minnesota law, is an annual, biennial, or perennial which is deemed by the Commissioner of Agriculture to be injurious to public health, public roads, environment, crops, livestock, and other property. In Minnesota, there are ten weeds on the primary noxious weeds list. They are:

  • Field Bindweed
  • Hemp
  • Poison Ivy
  • Purple Loosestrife
  • Leafy Spurge
  • Perennial Sowthistle
  • Bull Thistle
  • Canada Thistle
  • Musk Thistle
  • Plumeless Thistle

Most of these weeds are found in fields, waste areas, and along roadsides but occasionally they are found in our lawns. Along with the top 10 primary noxious weeds there are 49 secondary weeds that can be adopted by any county in Minnesota to be placed on the individual county list to be enforced. Enforcement of the noxious weed law is carried out by inspectors in townships and cities in Minnesota. According to the law the noxious weeds on this list must be controlled by all public and private land use in Minnesota.

October and November are the best times to deal with weeds when they are at their weakest point as they die back from frost and approach dormancy. Give Parkway Lawn a call if we can help get rid of a weed problem you have in your lawn 612-869-5878
