Effectiveness of members of the family Bacillaceae, isolated from agricultural soils of Krasnoyarsk region, against fungal diseases of potato

The purpose of research is to evaluate the effectiveness of representatives of the family. Bacillaceae, isolated from agricultural soils of the Krasnoyarsk Region, against pathogens of fungal diseases of potatoes. The antibiotic activity of 21 strains of p. Bacillus was studied using the counter-culture method, identified as members of B. altitudinis, B. atrophaeus, B. cereus, B. megaterium, B. simplex, B. subtilis and Bacillus sp. and 1 strain p. Peribacillus (identified as P. simplex), isolated by the authors from agricultural soils of the Krasnoyarsk Region, in relation to the causative agents of potato fungal diseases Geotrichum candidum (causal agent of rubber rot), Rhizoctonia solani (causative agent of rhizoctonia blight), Fusarium equiseti (causative agent of fusarium blight), and Alternaria sp. . (the causative agent of Alternaria blight). Of the tested strains, 3 strains did not show antagonism against the indicated pathogens, 1 strain was active only against Alternaria sp., 1 - against Alternaria sp. and R. solani, the remaining 17 strains showed varying degrees of antagonistic activity against all four pathogens. Alternaria sp. showed maximum sensitivity to the set of strains studied (the average zone of growth inhibition by strain is 11.17 mm), the minimum is F. equiseti (the average zone of growth inhibition by strain is 7.33 mm). For G. candidum and R. solani, the average growth inhibition zone across strains was 9.21 and 9.70 mm, respectively.
