Determination of the effect of the fungicidal concentration of the "Sandezvet" solution in the treatment of corn and wheat grain contaminated with fungi of the genera Penicillium and Aspergillus

This work aimed to improve and introduce a new generation disinfectant “SafDesInstrum” based on highly concentrated salt of quaternary ammonium (QAS) in the poultry industry to combat pathogenic fungi. Possessing broad bactericidal, fungicidal, and antiviral effects, SephDes Instrument is used in humane medicine for surface disinfection and pre-sterilization cleaning of instruments. In veterinary medicine, when this product was improved, it was given the name “Sandezvet”. During the research, standard methods of mycological analysis and guidelines were used to study the fungicidal properties and optimal regimens for the use of disinfectants. The work was carried out with test cultures of the genus Penicillium Link - Penicillium divaricata, Penicillium asymmetrica, Penicillium monoverticillata, Penicillium biverticillata, and Aspergillus Mich. The species affiliation was determined by comparing the cultural and morphological characteristics of the micromycetes. The drug «Sandezvet» provides a fungistatic effect on fungi of the genus Aspergillus fumigatus, Penicillium divaricata at 3 % concentration for 60 minutes. The most optimal effect of the product is an exposure of 5 % concentration for 60 minutes. Disinfectant «Sandezvet» at a concentration of 5 % exhibits general bactericidal and fungicidal properties and disinfects straw, husks, and wood shavings from bends within 24 hours. The product can be used to disinfect bedding material and grain in the form of an aerosol at the rate of 10 ml of the drug per 1 m2 of the treated surface
