I am writing up a research proposal for a new varroa treatment. It would
use a natural product. I need information on what products are registered
in different countries. I’d appreciate any information on what products
are registered, what the active ingredient is and what the relative price
is. Also how many colonies are in the country? Are they all treated? How
much treatment is there with “official” products vs. others?
I would be thankful for any information.
