Low-toxicity herbicide information

If you have thistles, knapweeds, oxeye daisy, scentless chamomile, or other noxious weeds, you can check out an herbicide called Milestone, which has a very low use rate, is labeled as practically non-toxic (for people, bees, birds, and aquatics and groundwater), and is not restricted use (no commercial pesticide license required).

If you have leafy spurge, hoary cress, perennial pepper weed, or cheatgrass, you can check out an herbicide called Plateau, which is also low toxicity. Our Extension office has these herbicides and a sprayer available for checkout. Thanks to a grant from the CO Dept. of Agriculture, there is no cost. However, there will be a $125 fully refundable deposit to ensure prompt return of the sprayer. You will have three days to complete your project.
