Brian Tassey,
In response to your two postings;
1. For several years, work has been done on developing a 'gelled
Formic Acid' formulation in order to reduce the applicator's exposure,
and have a prolonged, slow release application of FA. This was
initiated and supported by MEDIVET Pharmaceuticals of High River,
Alberta (ph. (403) 652-4441 / fx. (403) 652-3692).
There have been several collaborators with the testing, but the
principal investigator has been my colleague, Kerry Clark in Dawson
Creek ([log in to unmask]).
Although the product is not ready for releasr at this time, you may
contact these parties directly for more information.
2. Amitraz is undoubtedly very effective in controlling mites.
However, its toxicity profile and the nature of this product would make
me think twice ever to use on my bees. In 1990, I wrote a short
article on the product in response to the concern that Amitraz was
going to be used in similar fashion as has been reported on Apistan in
northern Italy; dipping plywood or cardboard strips in a solution.
Amitraz is an incomparably more dangerous substance than some of the
pyrethroids and I am not so surprised that the product is no longer
legally available for use in bee hives.
