Oxuvar 5.7% 275 g for 10-15 bee colonies (REG NL 116565)

Oxuvar is a ready-made oxalic acid solution. This makes it easy to prepare your own trickle or spray solution. For the oxalic acid trickle method, adding 275 g sugar is sufficient. Shake briefly until the sugar has dissolved. You can then trickle using a dosing syringe. Trickle about 5 ml per seam of bees.

Oxuvar can also be used to spray the bees. For this, dilute the bottle with 250 ml drinking water. Spray in a smooth motion about 6 ml per seam of bees.

Oxalic acid in powder form is available in 100 g and 500 g packs for, for example, cleaning equipment. Oxuvar is a product of Andermatt Biovet.
