Noxious Weed Cost-Share

The Longmont Conservation District Supervisors offer cost-share funds to landowners in their District to reduce or eliminate the infestation of noxious weeds on non-cropped land such as irrigation canals and fence rows. 

The cost-share is offered as reimbursement up to 50% of the actual cost of the chemicals not to exceed $100 per farm per year with a limit of $500 per individual or entity.  Targeted weeds in Boulder County are:  Canada, Musk and Scotch Thistle; Dyer’s woad; diffuse, Russian, and spotted Knapweed; Leafy spurge; Yellow starthistle; Purple loosestrife; and Dalmatian and Yellow Toadflax.  Targeted weeds in Weld County are:  Canada, Musk and Scotch Thistle; Field bindweed; Dalmatian Toadflax; diffuse, Russian, and spotted Knapweed; and Leafy spurge.  Only chemicals labeled for use on the targeted weed species are cost shared and must be applied according to the product label.  The Longmont Conservation District assumes no liability for any damage which may result from the purchase, storage, or application of any chemicals involved in this cost-share program.  Funds will be distributed on a first-come, first-served basis according to the date of the claim.

Please see the information brochure and the application for further details on the cost-share requirements or call the Conservation District Office at (720) 378-5521.
