Learn more about noxious weeds and how you can take action at mtweed.org, or MSU Extension. Contact your County Weed District to help you identify plants.

You can use the “Plant Sample Submission App” to submit a picture to the Schutter Diagnostics Lab at the Montana State University for identification.

Weeds often establish in newly disturbed areas that have been cleared, burned, or overgrazed. Promptly reseed disturbed areas with native seeds or plants to keep weeds out. Talk to your neighbors and develop a cooperative weed management group. It is more effective long-term.

Before traveling, clean or brush off your shoes and clothes, pets and stock, vehicles and tires and any equipment that can carry seeds or plants.

Dispose of seeds and plant parts properly. Check how to avoid transporting seeds at playcleango.org.

Some weeds can be dug or pulled by hand, while others can be controlled by mowing or grazing livestock at the appropriate growth stage for your target invasive plant. Other weeds may be treated with synthetic or organic herbicide. This requires careful application as overuse or misuse can greatly harm pollinators and native plants or create resistance in weeds.

The most effective approach involves combining multiple strategies, known as Integrated Pest Management (IPM), to prevent the introduction and establishment of weeds and pests by treating them with various control methods.

IPM strategies include checking throughout the growing season to spot weed seedlings, hand pulling, mowing, applying herbicide, and reseeding treated areas or exposed soil with native grasses and plants.

Most landowners can manage weeds themselves or with the help of a contractor. For information on control and eradication practices, as well as potential cost-share programs, visit your local county weed department: Flathead Co Weeds | Lake Co Weeds.
