In this study, it was aimed to determine the antagonistic effect between and isolated from eggplant roots and some root bacteria conditions. 24 bacteria were isolated from soil samples taken from the rhizosphere regions of infected and non-infected plants in different eggplant production areas and 22 of them were evaluated as candidate biocontrol agents. According to the results of the research, 13 out of 22 bacteria were effective against, 14 against, and 9 against between 40% and 100%. The most effective bacteria against were 22B (100%) and 11B (74.4%). Among the bacteria tested for effectiveness against, 3B (100%), 10B (100%) and 18B (100%) completely inhibited fungal growth. These bacteria are followed by 11B (88.85%) and 13B (85.55%). 11B and 24B inhibited mycelial growth of 100%.
