Antagonistic Activity of Bacterial Association of Apple Shoots Against Phytopathogenic Fungi

Microbial associations on surfaces and internal environment on shoots of apple sorts Golden Delicious, Wealthy and Berkutovka with symptoms of fungal infections were studied. 195 strains of epiphytic and endophytic bacteria, of which 8 strains had marked antagonistic activity against phytopathogenic fungi Alternaria alternaria, Aspergillus tubiengensis, Fusarium incarnatum equiseti, Fusarium tricinctum and Phoma fungicola were isolated. Antagonistic bacterial strains are identified as Bacillus amyloliquefaciens SA77, B. badius SA68, B. gibsonii SA104, B.
