If you don't mind multiple applications, vinegar works very well, even on
very difficult weeks such as White Top.  The roots depend on the above
ground plant for food, if you spray the plants with vinegar you are
depriving the roots of their food source.  As I said, it may take a few
applications, but it really does work.  Where I had areas of only "weeds" I
just took a jug of vinegar and sloshed it about.  Many plants, thought of as
weeds, especially grasses, like an alkaline soil and by adding vinegar, the
soil will become more acidic thereby making the growing environment less
friendly.

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!
