Thanks for bringing this up.

These chemicals have been tested and used successfully in Canada without the 
adverse effects being reported (yet, at least).

Can you help us out with some details, if you know them?

Specifically.

1. What application methods and doses were used for each acid in the trials?

2. What application methods and doses were used by the Swedish beekeepers 
who experienced problems?
