Randy,
I just finished reading your OA article. Looks like you put many hours into 
research.
I have got a question.
On page 1046 of your oxalic article you quote Anton 1999 by saying:

"The rub is, OA is only effective when dribbled in a sugar solution (Anton 
1999), not in plain water"

I was always under the impression that when OA was first tested in 
Switzerland by Imdorf Anton and the original 112 test colonies in 1994 & 
1995 the OA solution used was 30 grams of hydrated OA desolved in one litre 
of water .

Its late and i have not tried to track down the original studies but I did 
go to Allen Dicks web site and what he has posted says the first testing 
was only OA & water.

Has Allen got it wrong?
