Out of 282 isolates of epiphytic bacteria population originating from grapevine leaves 15% inhibited growth of Phomopsis viticola on potato-dextrose agar. Protective activity of 16 isolates, representing different morphological groups was tested on one-year old of grapevine stems fragments. Majority of bacterial isolates which inhibited the fungus growth in-vitro provided no protection of stems fragments against P. viticola. The efficiency of protection activity of bacterial isolates tested decreased with time. The most effective isolates of bacteria in protection of grapevine stemswere identified as Bacillus sp. and Pseudomonas fluorescens
