This stuff is readily available and a fraction of the price.

So can I just make my own fungicide by adding 20% into a spray bottle?

Guess I will go find out!

But this seems too easy. Has anyone else considered it before?

Found a guide on the right dosage: https://www.hunker.com/13406855/how-...as-a-fungicide

Don't get it near Dendrobiums I'm sure there are other genera that are also sensitive to copper fungicides.
