Greetings!
Having kept bees since 1984 at the hobby level, I have passed through
the beginning of both tracheal and varroal invasion, and their early
treatment consequences. Go to the following website:
http://apis.ifas.ufl.edu/frame93.htm
This index lists Dr. Malcomb T. Sanford's University of Florida's Apis
archives over the span of 1982 to his retirement by monthly content;
look at 1993, and in January, he reports Section three approval (for
general usage) for Miticure, the active ingredient Amitraz 10% in
plastic 90%. This was heralded as the first backup to Apistan, e.g.,
fluvalinate. In October of 1993, Hoerschel-Roussel Agri Vet Com
(HRAVC) withdrew the product from the market due to an undefined
problem that they could not explain.
There was much concern over this, and somewhat widespread use of
un-approved use of an uncut strip of the same product designed for
placement about the necks of cattle to kill ticks, but not labeled for
use with bees. A rumor said the trouble was a large beekeeper in
Florida sued HRAVC claiming that Amitraz killed a huge number of his
colonies, and won the suit. Supposedly factual information came to me
that this indeed was the case, and the economic hazard therein to HRAVC
immediately led them to simply withdraw the product from market.
I recall that Dr. Sanford somewhere in the aftermath, on the website,
stated that the Miticure product was still legal, but just unavailable.
I could not actually locate this item this morning however.
I personally erred in using Miticure in that on finding my breeder
queen's 4 frame nuc quite heavily infested with varroa, placed in it
TWO strips (equivalent to FIVE strips in a brood box); the result?
Every bee in the nuc dead the next morning. Remember, follow the
directions!
