Field experiments to determine the effect of Perizin on Varroa mite in honeybee colonies in Iran
Valiollah Bandpay And Mohsen Bahrami
Perizin was used against the Varroa mite in honeybee colonies in cold climate conditions when no brood was present. In 10 colonies with the recommended dose rate, a mean efficacy of 97.6% was achieved. In another experiment in mild climate conditions, when the least amount of brood was present in 10 colonies, four applications of Perizin emulsion at 4-day intervals and at half the recommended dose rate achieved a mean efficacy of 95·31%. The result for full dose treatment in the same experiment showed an efficacy of 96.02%.
