Prevent diseases with bactericides and fungicides

Physan 20 is also supposed to a fungicide as well, but I personally have not seen any positive result with the product. no desire to use it again.

Ditto. I keep Physan 20 around to disinfect table surfaces and such and also add it to the water in the base of my terrarium.

I use Phyton 27, which, unlike Physan 20, is a systemic on plants only when they do show signs of infection, but not generally as a preventative. On the other hand I may treat plants that were immediately adjacent to an infected plant, while at the same time moving the infected plant to quarantine.

As for calcium, I began using Botanicare Cal-Mag Plus (includes iron) this year, after a test of my tap water showed it to be low in calcium and magnesium. Sometimes I substitute or add a little epsom salts (magnesium and sulphur), as my tap water is also low on sulphur.

Physan 20 is almost like house bleach, I think.
It basically kills whatever's on the surface.

Anyway, when phyton 27 is used on "sick" plant, does it help clear the infection??
and in is copper based fungicide, but not used as bactericide, right?

Only sometimes, if the infection hasn't progressed too far. The jury's still out on a couple Phals I treated a couple months ago. Phyton is a bactericide and fungicide:
