The results of the isolates from the roots of, eggplant , diagnosis the presence of fungus F. solani that causes root rot of eggplant in six locations in the province of Babylon , Showed the results of an experiment pots under the conditions of the lathhous all treatments led to significant reduction in the severity of the injury for the isolated fungus (Fs6) F.solani All treatments Bacillus subtilis + Peudomonas fluorescens , and bacteria B.cereus + P.fluorescens and bacteria B.subtilis + B.cereus in the presence of pathogenic fungus that were used by 15 ml / potted a significant reduction in the percentage of the severity of the injury to the egg plants which was 6.25% , 6.25% and 12.5% , respectively, compared to the control treatment (pathogenic fungus alone ), which was 81.25%. As for the results of the experiment under the plastic house conditions all treatments results a significant reduction in the percentage of the severity of the injury for fungus (Fs6) F.solani between the made bacteria B.subtilis + P.fluorescens , and bacteria B.cereus + P.fluorescens and bacteria B.subtilis + B.cereus the presence of pathogenic fungus significantly results in the percentage of the severity of injury to the egg plants which was 11.75 13.00 and 14.25 %, respectively, compared to the control treatment of pathogenic fungus alone and that the severity of the injury was 85.00% Bio-fertilization with bacteria B.subtilis +P. fluorescens and bacteria B.cereus + P. fluorescens and bacteria B.subtilis + B.cereus results, in the increase in the productivity of eggplant with and without the presence of pathogenic fungus (Fs6) F.solani, reaches to 16.32, 14.69 and 13.31 kg / plant and 19.31, 18.34 and 17.93 kg / plant, respectively compared to the control treatment with and without the existence of pathogenic fungus, which has 2.04 and 15.07 kg /plant, respectively .
