could be powdery mildew, another very common rose problem. Are the white spots
sort of fuzzy? Do they rub off easily? If it is powdery mildew, treatment is
basically the same as for blackspot.

No they are really like bleach stains...the roses just didn't have any
color there. The ones badly affected by the black spot are just
shrivelled or completely dead. The rest have these .. bleach spots. I
wonder if they got sprayed with something.
