I wish I would have seen that article.
(thinking out loud)
I would guess that destroying a hive with a small amount of AFB would be
jumping the gun. The hive has not demonstrated a weakness, yet. If the
AFB gets worse the hive is not resistant and the genetics need to be
removed from the yard. If the hive cleans out the AFB then it is
resistant and you want those genes in your pool.
