Another way of cleaning up virus infected bulbs is by heat treatment.  It 
undoubtedly varies by bulb species and pest species, but 55 C for an hour 
is perhaps close to what you can do.  Rather than discard valuable but 
virus infected bulbs, try heat treating them first.

I don't know, does heat also kill mycoplasma?
