Cost Share / Eradication Program

The cost share/eradication program started in one form or another in the early 1980’s. At that time land owners with certain noxious weeds could apply for and receive herbicide to aid in the control of the weed infestation. There was no staffing to help land owners with the control work.

In the late 1990’s a cost share program for longspine sandbur and yellow starthistle(in the area where it is designated for control)was implemented. Staff was able to go out and survey properties with the presence of one of these weeds and flag areas of infestation. Then a commercial applicator was hired by the land owner to apply the herbicide. The land owner paid for the labor cost of the applicator and the weed board paid for the herbicide used.

The following list of weeds, are those that are targeted for cost share in 2020. If you have an infestation of one of the listed weeds you may qualify for cost share. The earlier in the season you contact us, the more likely it is we will be able to schedule the necessary work and the more likely we will still have the resources to do it. If you think you have one of the weeds on the list and you would like to participate in our cost share program, contact the office by phone, email or letter.


Highest priority:

Any Class A Weed (PDF) (Meadow clary and Clary sage are in this category)

High Priority:

  • Leafy spurge (PDF) – proven to be one of the hardest weeds to eradicate once it gets established, but control work every year can keep it from spreading to other properties/areas
  • Longspine sandbur (PDF) – hard to keep up with this one as the seeds get stuck in tires, on clothing, on animals and can drop off anywhere, but if ALL seed production is prevented it can be eradicated in 3-5 years depending on how long it has been going to seed.
  • Perennial pepperweed (PDF) – extremely limited in the county but due to the root system it may take at least 5-7 years of good control work to eradicate.
  • Puncturevine (PDF) - another one that is extremely limited in the county. Eradication can be difficult because this plant can germinate from seed, grow and start producing seeds in two weeks’ time, and there are many flushes of seed germination throughout the summer months well into fall.
  • Saltcedar (PDF) – currently we are not aware of any escaped infestations, but know there are quite a few ornamental plantings in the county. Any escaped infestations will need to be eradicated.
  • Scotch broom (PDF) – There are many ornamental varieties of broom plants. Most of them are not invasive but Scotch broom is. We do have some escaped populations in the county. If it is allowed to go to seed the seeds can last in the soil for 70+ years. It is a big problem on the west side of the state and we believe, due to the plants we find along forest roads, that seeds are unknowingly being transported here from the west side.
  • Tansy ragwort (PDF) – A total of 6 known sites in the county, all are in open forest settings, 2 have been eradicated and we continue to work on the other 4. 2 of those other 4 are close to being eradicated.
  • Scotch thistle (PDF) – This weed has been present in Stevens County for a long time, sometimes being brought in with contaminated hay or possibly seeds on equipment. Then getting spread further by birds and animals. We have been helping land owners since 2003, but we do have to limit how many years we can help each land owner.
  • Yellow starthistle (PDF) – Even though this weed is an annual plant and spreads only by seed it has been extremely difficult to eradicate from properties. We have had to limit the number of years we can help each land owner.
