This has been suggested for black spot. (Immunex) I have yet to find it in any local stores. Does anyone know where in NW WA I may be able to find this. I seem to have blackspot no matter how diligent I am about keeping folaige picked up and spent blooms cut off. My old bourbon roses suffer the worst. I usually try to garden organically but I'm not willing to sacrifice my old roses so would like to try this. Linda PNW WA horsehay@gte.net
