Thanks for the link.

From that I was able to find one of the papers in the primary
literature and what it says is that if you dunk some unfortunate
nematodes in 8% glyphosate they suffer from some level of degradation of
nerve function and that is the LD50. I would be a lot more wary of the
dithiocarbamide fungicide MZ.

(article behind paywall but abstract and figures are not)

But if you dunked them into 8% acetic acid or brine for 30mins or 24h
they would *all* be stone dead!

Whilst I could believe that if the wetting agent didn't kill you first
you might suffer nerve damage by ingesting huge amounts of glyphosate
concentrate I do not view it as a serious hazard. YMMV
