In my opinion the above post must represent the tolling of the bell for the
use of both Apistan and Bayvarol for the control of varroa. Resistant mites
in South Dakota last fall, in your hives next year, are we on the slippery
slope to calamity?.
 
Again in my opinion, the use of chemicals has played us false. I suppose
that the big chemical companies will just pocket the dollars generated by
Apistan and Bayvarol, thank you all very much, and let the R&D boys and
girls get on with replacing these two products with some other so called
treatment for some other problem. What's a few billion bees, when the P&L
accounts and the shareholders' interests must be protected?. Maybe now is
the time to re visit the FGMO option with significant research dollars while
we still have bees to be attacked by varroa.
