This study was carried out to evaluated the efficiency of Ginger plant extracts and their compatibility with four bacterial s pecies as agents for controlling eggplant plants infected by root rot disease caused by R. solani under laboratory and greenhouse c onditions. Results of the effect of Ginger cold water extract on radial growth of R. solani under laboratory conditions showed that treatments revealed positive effect in reducing fungal growth of pathogen and the effect depend on extract concentration, th e effect was increased when extract concentration was elevated, the inhibition percentage of the ginger cold extract ranged between 26.06% for the concentration of 100 mg/ml and 61.46% for the concentration treatment of 40 0 mg/ml. The results showed that t he concentration of 400 mg/ml completely inhibited the growth of the pathogenic fungus to 0 mm with an inhibition percentage of 100%. The results revealed that the alcoholic extract of ginger showed that the growth of the pathogenic fungus was completely i nhibited at a concentration of 20 mg per ml. The findings showed that B. subtilis treatment revealed significant excellence in growth inhibition as compa red with other bacterial strains treatment which recorded 69.76 % as compared to 31.29 and 56.61% for S treptococcus sp, and P. fluorescence treatments. Data showed that the bacterial suspension of B subtilis significant superior in increment number of germinated seeds and germination percentage which recorded 86.70 % and 8.67 seed / plant as compared to 7.3 3 seed / plant and 73.30 % of control treatment. The results revealed that the combination of B. subtilis bacteria and the alcoholic extract of ginger plant gave the highest significant values in increasing plant growth and disease index parameters.
