Weed Control Methods

The Pierce County Noxious Weed Control Board recommends an Integrated Pest Management (IPM) approach to noxious weed control.  IPM is the use of a combination of management tools that reduces reliance on herbicides and preserves the quality of existing habitat, water, and other natural resources.  Weed control methods we may apply to noxious weeds include:

 

weed control and prevention

   

Prevention - learning to recognize and eliminate invasive species before they gain a foothold

weed control and prevention

 

Cultural - such as crop rotation, soil tilling, pruning, thinning or timing fertilizer applications to reduce plant growth, and replant with desirable vegetation

weed prevention mechanical

 

Mechanical - such as pulling, digging, mowing, etc.

Biological - the introduction, or encouragement of parasites or predators of a pest species, like cinnabar moth to control Tansy Ragwort
