Fremont County Weed and Pest

Fremont County Weed and Pest Control District provides vegetation management services to many state and federal agencies. By filling a void in commercial applicator services in Fremont County, the District is able to provide quality weed control on public lands and rights of way that directly affect nearly every property owner and taxpayer in the county. The district charges for these services at market rates for herbicide and labor.

The District also treats weeds on privately owned non-crop sites for designated noxious weeds, bare-ground and treats some crop land for leafy spurge where other local commercial applicators are unavailable. There are several commercial applicators in Fremont County who take work on cropland sites and the district modifies its work load to prevent any direct competition with local enterprise. We do not retail herbicides in competition with local dealers.


  • Technical assistance to set up a weed or pest management program using integrated management.
  • Cost-share programs which reduce the cost of managing certain weeds or pests. These programs vary from district to district; check with your district supervisor for details and availability of cost-share programs in your county (designed by the District Boards).
  • Special programs may be established to meet specific local needs. If the problem is significant, some weed or pest species may be classified by law as "declared".
  • Provide an inspection service to attest your fields meet Wyoming Certification Standards and certify the resulting forages are certified weed-free.
  • Tap the resources of the Wyoming Weed and Pest Council, the University of Wyoming, the Wyoming Department of Agriculture, and various other federal, state, and private organizations.
