a randy Oliver snip followed by > my question...
Nancy, EFB appears to be a different critter than it used to be--it no
longer simply disappears when forage conditions improve.  And yes, varroa
doesn't do well in colonies that are having trouble rearing brood.

> the first question I normally ask in this situation is.... was the determination of EFB (or whatever disease/pathogen) based on a lab evaluation or a field analysis (ie horse back estimate)?

> there are any number of things which give the same symptoms as efb but are not. So from the get go knowing EXACTLY what the problem is would be important.  I have no hard data to back up my own supposition (beyond the efb kit says no) that some commonly applied agricultural fungicides produces symptoms that look amazing like efb < visually if there is a difference here the effected brood is in small patches and not randomly spread across a frame of brood.

>Here we do have episodes where efb shows up in the spring but quickly disappears when nutrition improves.
