I should have searched the archives before my post and I would have
remembered the FGMO discussion. I didn't enter the FGMO discussion at the
time.

Two facts stand out at Dr. R's site. Dr.R had hives which had survived four
years with no other treatment than FGMO with the Tobacco testing done. Dr.
R's controls all died. One thing about varroa testing the controls always
die within two years . Fact two is that Dr.R had been fogging with Tobacco
smoke every two weeks since 1998 to do a sticky board test. We have known
for years Tobacco knocks down varroa and is a excellent IPM method. Dr. R
knows also as uses the method for his tests. It would be interesting to see
if colonies would be alive after four years with only the FGMO. I suspect we
will be hearing from Dr. R when he reads this post.
The scientific reason why the FGMO works is not clear to me from reading
from the archives. Are the varroa DEAD or only knocked off the bee?

Ps. Dr. R has discontinued the fogger and is now using the cord soaked in
FGMO. In my opinion from only reading I wonder what kind of results might be
had with open mesh floors and the FGMO fogger. If  I am reading Dr.R's work
correctly he did his tests with solid bottom boards.
