Dear Ethan,
     I think the USDA APHIS people who control plant imports consider plum
pox transmission from seed a serious possibility.  At least they did 5 years
ago.  I had quite a few peach trees which I grew from Russian seed sent by
one of their experiment stations for trial here as rootstock.  When they
came here to check on my Russian plums for pox, they took samples of maybe
eight of these trees for plum pox testing and asked me to destroy the rest
if these proved clean.  It took 3 years, but they were clean and I destroyed
the rest.
