Two strains of bacteria isolated from agricultural soil in Yenisey Siberia were tested for their ability to suppress Fusarium root rot of soybean (Glycine max (L.) Merr.) in vitro . The strain RSA-1 statistically significantly (p<0.001) reduced the disease incidence by 25 percentage points in case of naturally infected soybean seeds and by 29 percentage points in case of artificially infected seeds. The strain RSA-13 statistically significantly (p<0.001) reduced the disease incidence by 32 percentage points in case of naturally infected soybean seeds but did not affect the disease incidence in case of artificially infected seeds. Both strains statistically significantly stimulated growth of infected plants. RSA-1 is Gram-positive, motile, aerobic, rod-shaped spore forming bacterium belonging to the Bacillaceae family. RSA-13 is Gram-positive, aerobic, filamentous actinobacterium belonging to the Actinomycetaceae family. Both strains can be recommended for biological control of Fusarium root rot of soybean in Siberia.
