remembering that water has an LD50 too. What is its mode of action, what

are so bloody sure it is nasty you must have this information to hand.
Surely.


LD50 for rats 4050 mg/kg
LC50 for rats (4h) 1.3mg/l air
(note greater than, implies they couldn't reach LD50).

So a 100kg person would need to ingest about 400g or 1lb of glyphosate
to have a 50% chance of killing themselves. I would suggest a more
active product would be better.

Note that diluted spray in the sprayer tank at 1.5kg active in 200L
means that you need to consume some 70L of product straight from the
sprayer. The acute lethal dose for water is about 5L, so you get to die
from water ingestion well before dying from the glyphosate. OK, that's
not the whole picture but you get the drift.

Glyphosate is rapidly excreted.

Non of which is borne out by the facts. millions of gallons are used
throughout the world, and it is extremely toxic. I think I would
prefer to trust those who do not have an "agenda" for it's use!
rather than those who earn a living from cutting corners.
