Does anybody out there know if Tylan is effective against EFB? Tylan is recommended for AFB only, as far as I know. Is this because it has not been tested against EFB or because it is not effective towards this particular bacteria? It seems intuitively unlikely that it would not be effective against both forms of foul brood.
I have been having an ongoing debate about this with another beek, so I thought I would consult with you all.
