Azalea and Rhododendron Diseases
When an azalea or rhododendron just "up and dies" on you, it's hard to figure out why.
Fortunately, the good folks at Pennsylvania State have gathered a compendium of diseases these shrubs get.
In my experience, most azalea/rhododendron problems are caused by them growing in clay soil. They are woodland plants..... and they demand highly enriched, fast-draining soil.
Phytophthora root rot seems to be the most common problem. See the Penn. State publication for a list of resistant and susceptible azalea cultivars.
