How many  have misused OA?  I have heard of a few who doubled the amount of 
OA in  solution or 
treated 2-3 times during brood season.


A lecture at Apimondia in Dublic 2005 described how the concentration of  the 
sugar syrup is more important than the amount of oxalic.  A stronger  
solution with (from memory) 3.2% oxalic was more effective than a weaker one  with 
4.5%. If anybody is interested I could check the figures to confirm.
