The usual figures you see quoted are a half life of 60 days. This can
vary.
with a half life of 60 days six months later 10% or so is still around.

I presume you are talking bout the half-life of the daughter products into
which the original glyphosate decayed. Are there any results which indicate
what sort of a hazard these daughter products might be to which forms of
life?

If the original glyphosate itself took so long to decay, there would not be
much by way of growth left in my garden.

Incidentally the other half truth is that it is destroyed on contact will
soil.
It isn't it can get bound up b ut not in all soil types.
