You beat me to it, pointing out the nomenclature.

However, the "horticultural disinfectant" is a 27% solution of hydrogen
per/dioxide, and there was no mention of that being diluted. I would be
remiss if I did not point out that diluting a 3% solution is not going to
*increase* the concentration to bring it up to anything near 27%...quite
the
contrary. If it takes a 27% solution to kill spores, then 3% is just going
to annoy them.

Well, the instructions resulted in a dilution that would be under 3%
if memory serves. I'll go back and check the pages and see if that's really
so. Again, even if 1% or less suffices, it'd kill only the spores, but
given
the cheapness and low toxicity, spraying with dilute hydrogen peroxide might
be worth the trouble...or not.

I'll have another look.
