Bonsai Nut alumnus... we miss you
Many here will say Banol but I have used Monterey Agri-Fos Systemic Fungicide with good results and it is far less expensive overall in that you can buy a smaller quantity like 16 ounce. I just poured it over the substrate after watering.
My rhododendron sits in a black pot, in my pretty organic nursery mix and basically stays pretty damp. It has grown insanely this year with no such problems... Are you certain it is root rot?
In the past I had found this pdf to be very helpful- http://cru.cahe.wsu.edu/CEPublications/eb1229/eb1229.pdf
