“…To search for effective control of phytopathogens, bacteria from the genera Bacillus, Pseudomonas, Serratia, Rhizobium, Streptomyces are most often studied [6,[8][9][10]. Bacillus strains of the genus Bacillus possess high antagonistic activity and serve as producers of biological substances: amino acids, amylo-, proteo-and lipolytic enzymes, as well as polypeptide antibiotics [8,11]. Identified strains of bacteria B. pumilis, B. methyloprophics, Brevibacterum halotolerans, active against a fairly wide range of apple mycopathogens [2,6].…”

To prevent phytosanitary destabilization in apple agrocenoses, it is necessary to include ecologically safe microbiological preparations in the protection systems. In the Krasnodar region in 2016 and 2019 in the field, laboratory samples of microbiological preparations were tested in the formulation “wettable powder” from the collection of the laboratory of the biological method of the FGBNU VNIIMK against Venturia inaequalis (Cooke) G. Winter. Of the 9 laboratory samples tested in 2016, the highest efficiency, approaching the effectiveness of a chemical fungicide, was shown by samples based on fungal producer strains: RK-1, XK-1 and T-2 - 76.9-92.5%. In 2019, all variants (in the amount of 4) using laboratory samples of microbiological preparations were more effective in comparison with the active substance of chemical origin. The best scab control was provided by a laboratory sample of a three-component mixed preparation based on two fungal and one bacterial producer strain RK-1 + XK-1 + B-12 - 83.0-84.9%. The isolated samples are promising for research on the creation of microbiological preparations against apple scab.
