I use anywhere from 1/2 to 1 Tablespoon/ gallon depending what size orchid
I'm working with, although to tell the truth, I've never had a problem with
the higher rate on anything. I use it to soak new divisions, spray newly
deflasked seedlings, soak pots, soak infected plants (esp erwinia brown
rot), etc.

What kind of mixing rate are you using for Physan?
