Testing two forms of rodenticide baits based on brodifacoum in vitro on Norway rats Rattusnorvegicus

The chemical method is the most common to control rodents. Fast acting rodenticides (zinc phosphide and krysid) and slow-acting rodenticides divided into first- and second-g eneration anticoagulants are used for deratization practice. The aim of the study was to evaluate the results of rodenticidal activity of brodifacum for two forms of rodenticidal baits in order to control rodents in settlements and adjacent territories, on agricultural land and reduce their harm. In case of high numbers, they carry such dangerous diseases as plague, typhoid fever, paratyphs, encephalitis, rabies, tuberculosis, tularemia, etc. Fleas and ticks parasitizing mouse-like rodents transmit pathogens to pets and humans. The economic damage caused by rodents is high. They destroy and spoil food and fodder, destroy the seedlings of agricultural crops. In a year, a gray rat eats 2024 kg of food and pollutes 10 times more products. In total, two forms of baits based on brodifacoum were prepared against rodents. We proposed and tested the rodenticidal activity of the forms of baits developed in loose and soft forms. The assessment established that both forms had high biological activity, reaching 90.17 and 89.67 %. Consumption rates of poisoned baits in the form of soft briquettes were lower compared to grain baits, showing high efficiency and saving the food base for preparation of poisoned rodenticidal baits.
