Does phostoxin sterilise?  I know it is effective against wax moth and small 
hive beetle but will it kill AFB, EFB and chalkbrood?

As for ozone, all the evidence I have seen and been told points to it being 
a good surface steriliser but has poor penetrating powers so would not be 
suitable for full sterilisation of combs.
