We have a lot of snow in our area and it lingers forever in the Spring. Last year was the same and I noticed like 4 plants had been completely consumed (killed) by this black/grey mold/mildew fungi. This year maybe 30 or more plants have this same blight. Does anyone recognize it and have a solution to eradicate it? I'd be much appreciative.

I've started spraying a fungicide on it but the "mold" is so powdery that the spray just rolls off it. Hummm..... Any suggestions?
