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.
