Again, I am in now way suggesting that any pollen sub currently on the market is superior to mixed natural pollens. On the other hand, several of them are clearly superior to the "natural" rust fungus spores that my colonies store as beebread in fall.
Randy, I am thinking not everyone here may be familiar with the rust spores you mention and the effects, It seems to me that is a good clue in understanding the bees do not always do the right things.
I would suggest you explain that a bit.
