In this paper, the biological effectiveness of a suspension of Streptomyces sp., isolated from saline soils of the Astrakhan region was studied when growing Red Scarlett potatoes in a small-scale production experiment. The results of PCR-diagnostics of potato viral diseases showed the effectiveness of the treatment with the suspension of the studied bacteria, which reduced the harmfulness of phytoviruses and restrained their development. The results of field trials suggest that the biological efficacy in treating with a suspension of the bacteria was 78,2%. An increase in yield by 32,1% in comparison with the control (without treatment) was established.
Keywords:Streptomycetes, potatoes, phytoviruses, insects - vectors of plant diseases, biological effectiveness, Astrakhan region
