"I recall that Sr. Barros uses propolis extract in his pollen supplement
recipe.  Has Sr. Barros or anyone seen any real-world reduction in AFB from
feeding propolis extract?"

Peter. I do not have AFB in my colonies, so I can not answer your question.
I can not give any prove of the usefullness of propolis. For me propolis at
the moment is more and "ideological" or "fate" thing. If it works for human,
if bees collected, if it works for modulating the inmune sytem, then lets
make it available for all the bees, not just the ones in the propolis chain.

I am very close to the uruguayan team of DILAVE that have been testing the
propolis for controling AFB, and they are a great research team. The key
discoveries are: 1.- the i no letal dose, 2.- the minimun is 72 ppm if I
reacll correctly.
