Eradicating Binding Weed
We have a lot of plants in our landscaping. One of them is very much unwanted. It is bindweed. I have heard of a mite that attacks only that weed. I talked to an individual from the Denver Metro area that said the County Extension office sent her a stem of the bind weed which was infested with these mites. She simply wrapped the infested stem around an actively growing plant and the mites did the rest. Can you provide me more information about this eradication method and where I could get a similar cure?

You don't mention where the bindweed is a problem (i.e. lawn or garden bed), so some of this information may not be relevant.
Bindweed mites can be used but are only effective in dry landscapes rather than irrigated lawns.
Bindweed mites distributed by the Colorado Department of Agriculture Insectary in Palisade. To order mites, please use their online order form at
More information on using mites for the control of bindweed can be found at
You may be able to obtain bindweed mites through your local CSU extension office. The following link includes all the county extension offices in Colorado.
If you determine that the use of mites is not a viable option for your landscape, other control methods for bindweed are available.
If you decide to use an herbicide, choose a systematic post-emergent product and follow the instructions very carefully taking precautions to protect your health and surrounding plants. Products containing the chemical quinclorac are most effective for controlling bindweed in lawns. Please keep in in mind that chemicals should only be used according to label directions, and that some lawn chemicals may leach into the soil and damge desirable plants. Most products listed for control of bindweed may not be used in your flower or vegetable beds, so read and follow the label exactly. Bindweed is frustrating at best, but with a focus on increasing the competitiveness of your lawn, over time you will see results. Increase the length of your turf, mowing to nothing less than 2 to 3 ½” (depending on turf species) and establish uniform irrigation. Focus on increasing and maintaining the health of your lawn through proper aeration, irrigation, reseeding, and fertilization. .
We hope this has provided you with useful alternatives in controlling this difficult weed.
