Can I use 'regular' fungicides for orchids?
I know orchid-growers use "special" fungicides like physan and phyton. I can't find them anywhere, other than online. I'm wondering if I can instead use the fungicides available at big box stores like Home Depot. I found several different kinds, like garden fungicide, house plant fungicide, etc. I didn't note the specific names and active ingredients.
Can I use these on orchids? Are they effective in treating diseases like leaf/black rot without harming the leaves? I've mostly catts, dens, and phals. What kind of "regular" fungicide do you use?
