That was something else I have tried, as I looked again at the bottle of concentrates I have, one of Fertilome's products has triclopyr and another had dicamba along with the 2,4-d. As I am watching the backyard these past few days, it is all yellowing and the bindweed is slowly withering. This was the area that I hit with a concentrate of 2,4-d and metsulfuron methyl. I was told it may take time but would work. Our biggest problem in central and western Kansas is that the field bindweed has become resistant to glyphosate and 2,4-d. I guess just had to continue on it, but now it is trying to poke in where some has established, hopefully the bermuda will keep it down, plus I spot treat whenever I see them. Today I did spread Tall Fescue underneath my tree along with some bermuda though it likes sun better, but I have more of it than others. Prior to doing that I had spread phosphorous in the area I tore up, worked the soil with my weasel and gave it some water, then today sowed the seeds, and applied scotts liquid turf grower. This particular area I had already gotten the weeds to die off, and it was loaded with earthworms. It was tough to level out due to the steep grade between my house and my neighbor, we'll see how it turns out since it is a shady area.

Bindweed is not a trivial weed to get rid of. His approach may actually work but it would take an entire season to get it all out. Since his is an organic site you may not appreciate this suggestion. It involves RoundUp but you do not spray the entire site. You put some RoundUp (undiluted) into a baby food jar. Then dunk a sprig of bindweed into the RoundUp and leave it there for several days. Supposedly the RoundUp will kill all the roots attached to that one plant. Then move to some apparently healthy bindweed and continue the process. I have only read about this approach. I'm lucky to not have bindweed.

You could apply Round-up to the vine ends that are on your property and it will be translocated to the root(wherever that is). Otherwise, pulling it up as it reaches your yard probably wouldn't ruffle any feathers. You would at least be controlling the growth in your yard. Also, depending on where you live, might there be regulations about yard maintenance? Some cities/counties may require the listing realtors to maintain the properties. I've lived in areas where that was the case.

UPDATE: Even though the Ladybird Johnson wildflower center assured me this one was the "good" one, I decided to err on the side of caution and pulled it up today. I must say, for how small the plant was it already had a substantial tap root! I'll keep an eye on it and keep yanking in the future if necessary. Thank you for all the responses!!!
