I haven't tried plastic but it should work if left in place long enough. How long I don't know. I do know that thinner black plastic lets enough light through to support some weeds. And amazing the heat some of them can tolerate. Temps under clear plastic is higher than black and you've seen how long some will keep growing under clear.
The problem area I have with Rumex would require me to abandon a planting of mixed ornamental reseeders that I hate to do. And plastic isn't practical for that. Plastic or anything that offers cover for voles is a problem for me. Even traditional mulches can do it. And if it keeps the soil cooler the earthworms stay closer to surface and mole damage increases. You live in the country too right? Ain't nature grand! I love reseeders in my plantings but that makes weed control all that more complicated and a PITA. We stubborn gardeners.

Yes, Dan, there is/may be an issue with bees with all this poison. This is my first year to use any of these chemicals (other than Roundup), but the bees have been long gone. :-( Not just honeybees, but all pollinators are a lot scarcer here than years ago. Lots of diversity in what's left - all sizes and shapes, mostly various bumble beeish looking things, but also various wasps and little bitty unidentifiables.
Shaub, have you tried black plastic to kill mugwort or Rumex? If I abandon this section of row, I think I'll try it rather than repeated spraying.
Lambsquarters is a totally different story. I wouldn't want to get rid of it entirely - too good to eat! Tho a bit of a nuisance to strip off the leaves. 

Sheep sorrel is tasty too, but a tiny bit of it goes a long way!
