Hi All!
 
Here is Vladimir from Belarus,
 
I use AMITRAZ three years and have found it enough cheap and convinient in .
 
Amitraz emulsion is sold here ander name of BIPIN in 1, 2 or 10 mililiter
ampulas especially for treating against varroa. I don't remember initial
concentration of amitraz in ampulas (I can find a reference later if anybody
need).
 
To use the bipin you need to solve 1 ml ampula in 1 liter of water (18-20C)
and use in a dose 10 ml per frame of bees.Bees must be in a claster
(temperature must be less than 8 C).
