Reading George Imirie's comments relating to the varying time periods
that people treat bee colonies with Apistan.

In other branches of agricultural industry agreed dates are stipulated
for various treatments (eg. Sheep dipping in England - or at least used
to be so!).
Relate this to comments found in previous mail(Horizontal and Vertical
Pathogen Transmission) sent by Peter Borst. Mon 07/01/2002

Would it be acceptable to do the same for Varroa/Tracheal mite.
And at the same time - insist that strips bought should be returned to
the supplier. If this does not occur, then quantity returned will
establish quantity sold next time.
This would allow proper disposal to be organised.
Also, limit the strips found lying in apiaries etc..

Arguments in the civil liberties realm surely are overridden by the real
need to control pesticide pollution at all levels and in all directions.

We are after all I presume - a responsible group of individuals caring
about  the environment.
