About a month ago there was a thread here about using vinagar as a

I cought the thread late in the discussion and so did not read the

I've used vinegar on a limited basis, mostly on walkways for the weeds
growing through the cracks. It has worked very well. What I like best is
that it's completely non-toxic.



Um, no it isn't non toxic. It's extremly toxic to soil biota as well as to
plants. If it weren't toxic, it wouldn't work. Admittedly, most of the

Lots of things are toxic to insects, or various kinds of bacteria, or
yeasts, that are not toxic to vertebrates. I think the questioner probably
understood that a pesticide must be toxic to the pest, and probably meant to
ask if vinegar would harm the plants or humans. As fallen fruit generates
vinegar (probably beneficial to the plant as a natural insecticide), and
many members of genus Homo use vinegar on salads, the answer would seem to
be obvious.

herbicide action is because of it's phytotoxicity, which is why you get
regrowth that must be retreated.

It's also darn dangerous to humans if you get it in your eyes, and I
wouldn't want to handle it without gloves either.

A whole industry needs to be closed down.

It's not organic either.

This will be news to vintners who permit air to reach their wine.

Or without negative effect on the soil.

See above. Nevertheless, it is not a good idea to drench the garden with
acetic acid. If you have done so inadvertently, follow with a dressing of
lime, which will turn it into calcium acetate, and rescue the pH.
