I've been growing roses organically for 15 years. They get black spots, but it doesn't kill them: I just remove the affected leaves by hand when I see them. You can spray afids off the roses with a jet of water, or flick them off with a finger nail, but mine get eaten by visiting birds who do the job for me!
