Rose Rosette, carried by a mite. Viral, no cure for infected plants. Plant removal after bagging, mites are on the plant not in the soil. Preventative measures are as for mites. This is all I know, there may be more to learn about it. I have not had it here yet but it is in our general area, mostly in the neighborhoods.

Well, technically the idea of heating a rose should be mentioned, but it is really something the big nurseries are into, and pathogens like black spot are the target as I recall. Many plants do not survive purification by heat, and I do not know much more than this idea that propagation stock is improved with these advanced methods. It is not something I could do at home.
