In Europe, many beekeepers have switched to using glycerin rather than
sugar as the humectant for the dribble. Google "oxalic acid treatment
table."
And Toomema published research that one can not use any humectant if one
applied 15 ml/seam of a diluted solution of OA.
The putative advantage of not using sugar is that the bees are less
stimulated to consume the solution.
This method is not yet an approved application method in the U.S., so I
cannot condone its use.
