Weed control practices
The King County Noxious Weed Control Program practices Integrated Pest Management policies. Controlling noxious weeds depends on the plant and the site. How you control a handful of new tansy ragwort plants by your mailbox will require a different technique than removing 10 acres of tansy ragwort spread throughout a pasture.
To help landowners choose the best control method for their weeds on their sites, the noxious weed program has developed several handouts. Best Management Practices (BMP's) give specific control recommendations and guidelines, including plant identification tips and impacts. Biological controls, such as insects or grazing mammals, are sometimes used for large, widespread weed infestations.
