It occurs to me that as blackberries are drupes, they are more absorbent than cherries. This means they'd soak up the permanganate (bad) and the petrol fumes (also bad) much more.
So I'd strongly advise against using permanganate on them, and against eating them if they've grown beside a busy road.
