The scenario George writes about is exactly what happened with Fluvalinate
in both Europe and the U.S.

The scenario above would have been quite different if we had had another 98%
control chemical (of a completely different chemical makeup) to alternate
with Apistan would it not George?  Be honest.

How long in your estimation would Fluvalinate taken to become ineffective if
alternated with another 98% control chemical ( we did have two completely
different chemicals available at the start of varroa mite treatment in the
U.S. - Coumaphos & Fluvalinate) ?
