I may be wrong but I would think there is some misdiagnosing of this rampant BBS spotting (no pun intended).
As most to all peoe have cameras, I suggest takung pictures and posting for confirmation. If its a tree you own and want definite confirmation, email ohotos to Randy Ploetz.
By the way, the grove that I initially saw effected two years ago did not show its initial signs as the leaf spots, it was some signs on the branch ends and mostly and mainly the damaged fruit.
