This is interesting. Never thought of that. I was going to spread
some manure around the base of the blackcurrant bushes and let it rot
down.
Put your manure down as soon as you have cleaned up the area around the
bushes. It should not be fresh - use well matured FYM or stable manure.

Are you suggesting using bonfire ash to deter aphid ?
No, it is to provide potash - much welcomed by all soft fruit bushes.
