As a chemist, it sounds to me like a theory devised by someone
who doesn't understand what's going on. It's not *oxygen* that
plants need at their roots, but *air* *exchange*. Of course,
that subsumes a good supply of oxygen, but I'm quite certain
that oxygen is hardly the sole issue.

If your plants are suffering because of lack of oxygen at the 
roots (ooops, what did I just say?), the solution is to use a 
potting mix with better aeration.

Hydrogen peroxide has one valuable horticultural use:
sterilizing seed before sowing. There are some seed-borne
diseases that can be controlled that way.
