Interesting leap.   Honey is anti-bacterial AFAIK, but on to the second 
part... "chemicals, that kill beneficial bacteria".

This work is quite interesting, but contains words like "should" and 
"probably" and presents a plausible theory.

It seems we think some LAB and their products should/could suppress AFB, but 
apparently we do not know how to ensure that these LAB are applied reliably. 
Yet, anyhow.  It seems that often they are not doing the job very reliably 
or we would not be discussing this here, now.  And, is there an ideal level 
of LAB, or are there adverse effects if they get out of control?

At the same time, we know for sure that some "chemicals", like 
oxytetracycline (OTC) and Tylosin actually do prevent AFB development in 
larvae and we know how to apply them in appropriate doses. That is not 
saying that everyone does.  We know that overdosing and under-dosing 
happens.

And I don't know, but I am sure someone reading knows: Are LAB affected much 
by OTC and Tylosin?  It would be interesting if they are not.
