I have to say to start I don't know the answer and I am asking questions to
try to work one out. The reason I doubt the crossover from root to root
idea is that glyphosate is said to be quickly deactivated in contact with
the soil so it seems a bit much for it to cross two membranes and the soil
and arrive intact. The idea that ivy draws on the fluids from its host
seems a more promising mechanism to me. If anybody has any references to
that I would like to read them.

no actual references beyond general biology texts
which do show that fungal hyphae can move nutrients
around between plants or from the soil into plants
(they do act as a phosphate transport).
