Randy,
I really meant to write :
Taking the accepted formulation of 1 litre of water/ 1 kilo of sugar,
then to a litre of the resulting mixture add 35 grammes of Oxalic
di-hydrate to prepare a varroa controlling mixture.
I apologise for the confusion I may have caused and hope people note
well the correct formulation.
Thanks for the advice on water quality.
Regards,
Peter
