While gyphosate is not
'organic', it will not leave a residue used in that way.

It will not leave a residue in soil, but it will leave it in the plant.
Thus herbicides will be present in the parts of the plant to be eaten
and will enter the food chain.

Any green plant with glyphosate in it will be dead inside two weeks. As
a translocating weedkiller it is very effective.

The only plants that can survive are the GM Roundup Ready stuff that
contain a soil fungi gene that can detox glyphosate in real time before
it can harm the plant. This isn't an issue in amateur gardening (yet).

Hit something green with glyphosate spray by accident and you have to
chop it off to be certain of saving the plant. A few heavily waxed
plants can resist it (holly seedlings sometimes do), but I would not
like to rely on this.
