WINTER DRIPED: Dosage: drip with syringe 8-10 ml of warm solution per frame. Use 50-80 ml per colony Preparation: for a 275 g bottle add 275 g sugar and mix (1:1 solution) DRILLED OR SPRAYED SUMMER: Dosage: for swarms use 20-25 ml per kg of bee mass, for nuclei and colonies without brood spray 2-4 ml per side of frame. Preparation: for 275 g bottle add 250 ml of drinking water.Posology and route of administration The product should be used as follows : A) Application by drip: Preparation of ready-to-use 3.5% (m/V) oxalic acid dihydrate solution for drip: Pre-heat the container of oxalic acid dihydrate solution in a water bath (30-35 °C). Remove from the water bath and open the sealed container. Add the required amount of sugar (sucrose) of the type used for bee feeding: - 275 g sugar when using the 275 g bottle - 1 kg sugar when using the 1000 g bottle Close the container and shake vigorously until the sugar has completely dissolved. The solution is ready for use and should be applied lukewarm. Administration Fill a syringe (60 ml) or similar device through the wide opening of the container with the required amount of ready-to-use solution to treat one colony. The dose per frame is : 0.25 ml/dm2 for Western/Central Europe and 0.4 ml/dm2 for Southern Europe. For two-chamber Beehives, drip the lower nest first and then the upper nest. Mite drop will continue for 3 weeks The ready-to-use drip solution is sufficient to treat 6 to 15 colonies when using the 275 g bottle or 20 to 50 colonies when using the 1000 g bottle. The ready-to-use drip solution should be used immediately and cannot be stored after preparation. B) Application by spraying: Preparation of ready-to-use 3% (m/V) solution of oxalic acid dihydrate for spraying: Add drinking water to the solution: - 250 g (250 ml) of drinking water when using the 275 g bottle; - 900 g (900 ml) of drinking water when using the 1,000 g bottle, Close the container and shake. The solution is now ready for use. Administration Fill a hand sprayer or similar device with the required amount of ready-to-use solution to treat one colony. Spray 2-4 ml of solution on each side of the frame covered by the bees. If only half of the frame is covered with bees, the dosage should be reduced by 50%. The maximum dose is 80 ml. The total volume required varies according to the type of Beehive: - Colonies without brood, artificial colonies without brood or swarms newly placed in the Beehive should be treated with a dose of 0.3 ml/dm2 of frame completely covered with bees and for most hives. - Swarms, artificial swarms in glomeres should be sprayed with 20-25 ml of ready-to-use spray solution per kg of bees. For accurate spray dosing with your hand sprayer, spray 10 times into a measuring cup and calculate the volume for each pumping action. Calculate how many pumping actions are needed to treat one side of the frame. The frames should be sprayed at a 45° angle so as to minimize direct spraying into the cells. Mite fall will continue for 3 weeks. Treat swarm, artificial swarm or artificial broodless colony in spring/summer as a single treatment when most bees are inside the Beehive (in the evening). The ready-to-use spraying solution is sufficient to treat 5 to 10 colonies using the 275g bottle or 25 to 40 colonies using the large 1,000g bottle.
