Ivan, your suggestion makes no sense at all.
Perhaps you are thinking insects?
We are talking about fungi, and not about Spider Mites or aphids.
Fungus issues need fungicides, and NOT letting the leaves wet in the evening, and NOT letting organic matter such as old leaves on the soil and so on.

I’ll follow your suggestions Clicio, thanks Ivan for your attention. Thank you both.

Oops. There have been so many questions about insects lately I was sort of on automatic pilot. Forget what I said, unless you find bugs after you get rid of the fungus.

It's beginning of semester and I am trying to figure out how to handle all the new processes, including technology that doesn't work.
