Douglas County Noxious Weed Control provides this information as a courtesy (disclaimer) to those who are interested in controlling noxious weeds. We recommend a combination of two methods below (an integrated approach) to effectively control an infestation. If you prefer to have a Commercial Company take care of your Control needs, you can visit our Contractor's Page or use any Contractor found in the Yellow Pages. Equipment may also be available at a local rental store.

Remember, no matter what method(s) is used, ALL AREAS of the property must be maintained. These areas include around fences, poles, mounds, holes, hillsides (no matter how steep), and any other areas that may require specialized control.

Mechanical Control




Mowing Late Spring to Late Summer
bolting to flowering stalks
before seed formation
Mowing too early may cause repeat mowings soon after. Once seeds begin to set, they may continue to develop in the seedhead after a mowing.



Digging - You do not have to remove the entire root, but you have to go deep enough to get the crown (sits just beneath the rosette) Dig at least 6 inches below the rosette or plant.

Handcutting - Remove seed head and dispose of. Then chop as low on the plant as possible. Dig up the crown.

Biological Controls
There are Biological Controls (insects) available for Musk Thistle, but they haven't proved in Douglas County to work past the terminal blossom (the single tallest blossom). This is due to our climate and region. Therefore, Douglas County Weed Control will not accept the use of these controls as a viable tool.

Control Method Recommendation
Note: Improving the conditions and competition of desirable grasses and vegetation is the best defense against noxious weeds. Avoiding waste areas, overgrazing, disturbed ground and proper care of existing vegetation, will aid in keeping noxious weeds away.
