I haven't heard of this one. I have heard of chalkbrood supposedly stopping
AFB which in my experience is not right. I have seen plenty of case with
both AFB and chalkbrood in the same hive. Where does this claim about
stopping EFB come from? I have seen a couple of cases of both EFB (my
diagnosis) and chalkbrood in the same hive.
