>>Also there are many tests which have been done on dribbling in 
summer. The effiacy is LOW! Most tests show 40-60% after three 
treatments with some brood and egg kill.

It does not make sense to use OA with sealed brood.  Low efficacy and 
risk of injury to the queen with repeated exposure.  As far as I 
know, no one recommends it.  I would not use it that way.

>>Oxalic acid use around the world is not new news. Perhaps to many 
on this list.

Yeap, I read the Russians used it back in the early 80's.

>>Controlling varroa is a never ending problem with the above soft 
treatments. You knock varroa back and hope varroa will not raise to a 
level at which no treatment will save the hive before you knock 
varroa back again.

For sure - until we develop resistant/tolerant bees that are 
productive. :)

>>Reports of formic acid eating up the nails in bee 
equipment are already being heard out of Canada.

I may be wrong but this sounds like chemical abuse.  The nails are in 
the wood and the acid would have to penetrate the wood to get to the 
nails.

>>Several beekeepers have questioned my sanity in running a small 
cell experiment this season. Certainly not the first time!

Bob, I am thinking of trying small cell myself :) next year since 
I've seen 5,0 mm in the center of brood combs of thriving feral 
colonies.  It will be nice to see 4.9 mm in action for myself.
