WINTER DRIP: Dosage: drip with syringe 8-10 ml of warm solution per frame. Use 50-80 ml per colony Preparation: per 1000 g bottle add 1 kg sugar and mix (1:1 solution) DRILLED OR SPRUZZLED SUMMER: Dosage: for swarms use 20-25 ml per kg mass of bees, for nuclei and colonies without brood spray 2-4 ml per side of frame. Preparation: for 1000 g bottle add 900 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: Preheat 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.

The 3M 6200 reusable semi-mask respirator is easy to use, lightweight and requires minimal maintenance. The respirator is sold with a pair of Class A1 filters suitable for respiratory protection from organic vapors with boiling points above 65°C (e.g., oxalic acid). The nape cap is designed to ensure a snug fit and to facilitate lacing behind the neck. The soft elastomeric facepiece and light weight (82 g) provide excellent comfort even for prolonged periods of work. The compact design minimizes obstruction of the field of view and makes it easy to handle. The two-side filter attachment system offers minimal breathing resistance. Filters (class A1) for organic gases and vapors model 3M 6051 are suitable for paints, solvents, organic fumes (e.g., oxalic acid) and nuisance odors. Suitable for 3M 6000 Series and 7000 Series 3M semi-masks and full-face masks The dual-filter design offers good balance and a panoramic view The filters can be used with all 3M semi-mask and full-face respirators equipped with a bayonet coupling system The bayonet coupling allows the filters to be easily snapped on
