Default Appropriate fungicide

Question: If the St. Augustine website calls for a copper-based fungicide for an issue, would Physan 20, which doesn't contain copper, still be an appropriate fungicide? The issue is brown spot at the leaf apex and moving down the leaf of a paph.

Physan 20 isn't going to do much. Good for getting rid of algae on the greenhouse floor, surface stuff only.

I think they mean Bordeaux mixture.

Or Phyton 35, a copper-containing fungicide.

Copper-based means copper based.

Physan is a disinfectant, not a fungicide, per se. It will kill fungi, bacteria, and viruses to which it comes in direct contact - not those infecting organisms.

Or Phyton 27 may be easier to get... the two Phytons are similar.
