The β-exotoxin containing enthomopathogenic strain B. thuringiensis 994, in first two days after processing the potato plants with the bioinsecticide, promotes the decreasing a number of ammonificators, fungus and streptomycetes. The β-exotoxin not containing strain B. thuringiensis 787, for the second days leads to inhibition the fungi growth. However, in 7 days after processing were observed the full disappearance of bioinsecticides influence that was expressed in restoration of phylloplana microbiota. Chemical disinfestant Calipso, for all period of researches, causes the inhibition the streptomycetes growth. The strain B. thuringiensis 994 and 787, showed the antagonism to phytopathogenic fungi Fusarium oxysporum and Alternaria solani. In comparison with Calipso, it is the most active on phytopathogenic fungi influences was the strain B. thuringiensis 994, which producing the thermostable β-exotoxin.
