Application in beekeeping
Varroatosis is a chronic, parasitic disease. The causative agent is the Varroa mite. The disease has not yet been fully understood, so there is no way to completely get rid of the disease. However, there are tools that give a good result with system processing. JSC "Agrobioprom" produces Bivarool for bees.
Bivarool: composition, release form
The drug is sold in the form of glass vials and ampoules with a capacity of 1 ml and 0.5 ml, respectively. The substance has an oily consistency. Fluvalinate is the active ingredient of Bivarool.
Pharmacological properties
Bivarool preparation for bees is characterized by a pronounced acaricidal contact effect. Destroys adult Varroajacobsoni. Prevents the emergence of drug-resistant tick populations.
Instructions for use
The treatment of bees with Bivarool is arranged 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 exclude the ingress of chemical particles into honey. Be sure to unpack Bivarool before preparing the mixture.
Dissolve Bivarool for bees in 1: 1 proportions in boiled water at a temperature of 40 ° C. A 0.5 ml ampoule will require 0.5 liters of warm liquid. Stir until a homogeneous mixture of milky color appears. For convenience, the solution is drawn up with a 10 ml syringe. Repeat the processing procedure again after a week.
Dosage, application rules
With regular treatment with the same means, the Varroa mite develops a stable immunity. Therefore, many beekeepers in reviews often recommend alternating Bivarool with other chemicals for bees from mites. New methods and options for conducting treatments appear.
If you combine Bivarool with water according to the instructions, then under the influence of a 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 served twice with a time interval.
In advance, paper smeared with petroleum jelly is lined at the bottom of the hive. This technique is necessary, since the ticks are crumbling while they are still alive. There is no need to expect an instant effect. The result will be visible in 12 hours.
When processing bees with an aqueous solution of Bivarool using a smoke gun, kerosene can be replaced with vegetable oil. Both methods are repeated after a week.
