Wild black raspberries in this area carry a virus that will gradually,
over several years, render red raspberry and blackberry plantings
useless. ... If it is present, I don't know how far it travels; though I'm
fairly sure it's more than twenty feet.

My black raspberries are twenty feet away from the red
raspberries which
are six feet away from the blackberries. So long as I deeply till
between
the varieties to prevent invasiveness, I have had no (NO) problems
in twenty
plus years. I have not seen a single interchange of diseases . My
ONLY
problem is that my next door neighbor grows wild raspberries and does
nothing to control Cane Borer which makes extra work for me every
year.
