Vinegar for weeds

Dell writes that his vinegar potion only kills the tops of undesired plants...
On this, long ago in our "Kill-raspberries-et-al.-that-competes-against-spruce-&-fir" course in Forest Management @ UNB, Canada, we were instilled with the notion that "weeds" are best dealt with near the end of the growing season when they have used up all their resources.
Perhaps timing is a concern here.

I have used "horticultural vinegar" (20%) on my most hated weed, mugwort (Artemesia sp), and it only kills the tops. New growth returns from the roots in no time.

I couldn't tell whether anybody replied to Alberto's query about using vinegar on weeds.
Yes, it works on most but not all weeds. Spray cooking vinegar (5% acidity as sold in
the USA) on young weed seedlings. It seems less effective on older seedlings or plants,
especially dandelions.
By the way, judging by the number of people writing me privately for unobtainable plant
material, this is by far the most gullible plant group to which I subscribe.
