Fungicidal activity of experimental samples for dry foot bath

The purpose of the study is to determine the activity of the developed experimental samples of a complex product for the group prevention and treatment of infectious diseases of the distal extremities of cattle against microscopic fungi of the genus Aspergillus, Fusarium, Penicillium and Candida. When selecting components for creating experimental samples of a product in powder form for group prevention and treatment of infectious diseases of the distal limbs of cattle using the dry foot bath method, the presence of adsorption, bactericidal and fungicidal properties was taken into account. The following components were used for dry foot baths: adsorbents (bentonite, zeolite, kieselguhr), sodium benzene sulfochloramide, sodium hydroxide, calcium hypochlorite, zinc oxide and sulfate, copper sulfate and additional components taken in various proportions. The fungicidal activity of experimental samples coded CB, CB1 and CB2 against microscopic fungi Aspergillus, Fusarium, Penicillium and Candida was determined in accordance with Guideline 4.2.3676-20 “Methods of laboratory research and testing of disinfectants to assess their effectiveness and safety ". The greatest fungicidal activity against yeast fungi C. albicans (concentration 4 %, 60 min of contact), filamentous fungi A. niger, A. flavus, F. poae, F. sp, P. sp and P. notatum (concentration from 4 to 6 %, 120 min of contact) showed a sample coded SV. The remaining samples SV1, SV2 and Lubisan Eco turned out to be less effective and had fungicidal activity at a concentration of 6 to 8 %.
