Disease on Azalea

Question

I have a couple of azaleas that have the white looking leaves that I read about in this article, and it said to use fungicide. What kind should I use? At first it was just one plant, but now it appears to be spreading!

Answer 1

Neem oil makes an effective fungicide. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
