rate, distribution, and loss of active ingredient.

Absolutely!  See Medhat's reply.  Apivar is clearly the best way to
administer amitraz.

Yes, the Penn State team found that Taktic was 4x as toxic to bees as
amitraz alone, apparently due to the adjuvants.

I'm not saying that Apivar caused noticeable harm to my nucs, nor am I
saying anything negative about the product in any way.  I was approached
early on by the registrant for my opinion on whether they should pursue
registration of the product in the U.S., and I encouraged them.  But I am
neither a salesman for, nor activist against any product or beekeeping
practice, so long as it does not tarnish the good name of honey.

In this instance, I used the product as the varroacide of choice for a
field trial, taking all factors into consideration.  I was merely asking
for others' field observations.
