That’s more oxalic acid than I’d have guessed.

Treating bees for varroa more takes about 25g of oxalic acid per box of bees. I’d kind of hoped the leaves might have more oxalic, then I could have tried putting rhubarb leaves in there instead of battling fumes, glycerine and strips of paper.

Some beekeepers where I live put strips of rhubarb stalks in the hives to treat varoa. Not sure how effevtive it is though.
