Bivarool is a chemical developed for the treatment and prevention of varroatosis in bees. The active properties of the drug are enhanced due to the presence of fluvalinate in the active substance. The active element is a component of products that are used to protect crops from pests. The drug was produced with the help of the Russian Ministry of Agriculture.
Application in beekeeping
Varroatosis is a chronic, parasitic disease. The causative agent is the Varroa mite. The disease has not yet been fully studied, so there are no ways to completely get rid of the disease. However, there are products that give good results when used systematically. CJSC Agrobioprom produces Bivarool for bees.
Bivarool: composition, release form
The drug is sold in the form of glass bottles and ampoules with a capacity of 1 ml and 0.5 ml, respectively. The substance is a liquid with an oily consistency. Fluvalinate is the active ingredient of Bivarool.
Pharmacological properties
The drug Bivarool for bees is characterized by a pronounced acaricidal contact effect. Destroys adult Varroajacobsoni.Prevents the emergence of tick populations resistant to the drug.
Instructions for use
Bees are treated with Bivarool with the arrival of autumn and spring. When the ambient temperature drops below + 10 °C. However, you should have time to complete the procedure 10-14 days before the start of the honey pumping process. Then it will be possible to prevent chemical particles from getting into the honey. Be sure to unpack Bivarool before preparing the mixture.
Dissolve Bivarool for bees in boiled water at a temperature of 40 °C in a 1:1 ratio. A 0.5 ml ampoule will require 0.5 liters of warm liquid. Stir until a homogeneous milky mixture appears. For convenience, the solution is drawn up with a 10 ml syringe. Repeat the treatment procedure again after a week.
Dosage, rules of use
With regular treatment with the same products, the Varroa mite develops stable immunity. Therefore, many beekeepers in reviews often recommend alternating Bivarool with other chemicals for bees against mites. New methods and treatment options are emerging.
If you combine Bivarool with water according to the instructions, then under the influence of low temperature the particles of the substance will simply settle on the frames. To prevent this from happening, it is necessary to add 60-65 ml of kerosene to the already prepared chemical mixture of 0.5 liters. Shake everything thoroughly. The resulting solution is poured into smoke cannons. Thanks to kerosene, the smoke will be drier and more penetrating. The jet is supplied twice with a time interval.
In advance, the bottom of the hive is lined with paper greased with Vaseline. This technique is necessary because ticks fall off while still alive. You shouldn't expect an immediate effect. The result will be visible after 12 hours.
When treating bees with an aqueous solution of Bivarool using a smoke gun, you can replace kerosene with vegetable oil. Both methods are repeated after a week.
