- Revegetation is the key to any weed control program. If dense stands of noxious weeds are removed through any control method, the vacated area will be open to further infestation if not reseeded with a more desirable species of vegetation.
- Hand Pulling can be very effective for small infestations of most noxious weeds. However, keep in mind that plants can still produce viable seed if left laying on the ground. We recommend that you pull any open flower/seed heads and dispose of them in a safe manner to prevent further spread.
- Tilling can also be effective, especially on larger infestations of annual or biennial species. Remember to re-vegetate the area with desirable plants, or noxious weeds will re-establish. Tilling is not recommended for most perennial species as root fragments may spread, causing an increase in the infestation size.
- Biocontrols in the form of bugs (weevils, gall flies, midges, etc) and other pathogens are available for several species of noxious weeds. Many of the biocontrols are available free of charge, contact the Noxious Weed Office to check on availability. Biocontrols do NOT constitute control as stated in RCW 17.10, but will assist in your weed control efforts.
- Herbicides that are site specific and selective are also an effective means of control for most species. However, each site and weed species are different, so call the Noxious Weed Office for a recommendation that will suit your needs and site. Or, you can research the options yourself by reading the Pacific Northwest Weed Management Handbook.
For site specific recommendations, we offer free on-site consultations. We will survey your property, let you know if there are noxious weeds present, discuss control options, and assist in weed control plans that can help you meet your goals for your property.
