Liebig-Dispenser
The Liebig-Dispenser was developed together with the famous German bee scientist, Dr. Gerhad Liebig, University Hohenheim.
It guaranties a safe, simple, highly efficient and bee friendly treatment with formic acid at a competitive price.
Application
The bottle filled with formic acid is placed on the main board with one paper-wick. Formic acid evaporates from the paper-wick of the Liebig-Dispenser slowly and steadily within the hive. The evaporation rate is adjusted by the size of paper-wick area. Thus allows an even and bee-friendly treatment against the Varroa with formic acid.
Timing/Dosage
Two treatments with formic acid 85 % beginning of August after the last honey harvest during 3-4 days / 50-150 ml beginning of September after finishing feeding during 2-3 weeks / 100-200 ml
Unit
1 Liebig-Dispenser contains:
Baseplate, 4 paper wicks, dropper, 250 ml bottle
Concept of control
A combined application of the Liebig-Dispenser with an oxalic acid treatment in broodless colonies (November-December) has proved very efficient against the varroa mite.
