Banana or Banana skin added on top of the frames of a hive in spring was thought to cure Chalk brood. The fact that chalk brood is often a short lived affair occurring in damp springs that naturally disappears as the weather warms and dries up was neither here nor there. It was the banana that cured it ....except in chronic cases where it obviously didn't....and then you really need to re-queen to a chalk brood resistant type.
