Glyphosate has no effect on plants once it gets into the soil. It has to actually be sprayed on the _leaves_ to act. There is some flimsy evidence that it might affect insects (as in: we drenched the insects in it, and noticed some effect). And finally, it'll be completely gone within a year or so. Its half-life is around 50 days.
