I was just looking at my Azaleas and Irises yesterday and notice some kind of white spots, I am sure its not good and I should treat it. What should I do to remove the spots?

I can only guess a fungus without a photo. You can try a fungicide you spray directly on the leaves. If that doesn't work go for a systemic fungicide that you mix with water and you apply it around the base of the plant.

Does it look like someone took powdered milk and splashed it on the plants and then it dried? If that is what it looks like then it is definitely a fungus. Hopefully a spray will take care of it. I own a landscaping company and what I encounter in my area the most are Azaleas, Rhododendrons, Mt. Laurels, Dogwoods and Roses with this problem. But I am sure the Iris is a potential candidate. If you have to resort to the systemic fungicide DO NOT use it around stuff you are going to eat like tomato plants, peppers, lettuce, etc...
