That makes some sense.

But again, if my soil gets "infected" by Bt with repeated
applications, I can stop buying the stuff and just
dust the leaves with the infected soil year after year, right?

That is, dryness doesn't kill it. Wetness doesn't kill it. So where
does it go, once it's in soil? I guess
something else in the soil must kill it. Nothing to live on there?
Well, I'd say the same thing when it's
dissolved in water, but it seems to do just fine that way. Powder and
liquid forms of Bt are active, I am told,
for years.

Logic is only as good as its' premise.
