Study of the efficiency of suppressing fire blight by bacteriophages under laboratory conditions
Experimental Biology and Biotechnology(2022)
摘要
Erwinia amylovora bacteriophages Hena2, Roscha1, Pixel, Dichka and VyarbaS were studied as a biological fire blight control agents on model objects – pear flowers and leaves. When treated with a bacteriophage 1 h before inoculation with E. amylovora 1/79Sm, no statistically significant differences in symptoms were found compared to the control. However, a decrease in the titer of the pathogen by 1–3 orders of magnitude was shown with E. amylovora in the inoculum of 106 –108 CFU/mL and treatment with a bacteriophage 1 h before infection with the pathogen.
