Sugarcane crop has attained the most significant position in the agrarian based economic country of India. The crop is source for the production of various valuable products which have become a part and parcel of daily needs. However, occurrence of disease especially; red rot disease is affecting the health status of crop. The disease is adversely affecting the economic status of crop. It not only affecting the growth and yield; but also, degrading the quality of juice. Thus, various biological strategies have been adopted for their effective management of red rot. As such, the present study dealt with comparing the in vitro efficacy of endophytic and rhizospheric bacteria isolated from sugarcane crop for suppressing the red rot pathogen. In the current study, total 51 bacteria were isolated from the sugarcane plant; 16 bacteria from the internal root tissues and 35 bacteria from the rhizospheric soil. Further, when the isolates were checked for in vitro antagonism against C. falcatum; it was found that a major proportion of endophytic bacteria isolated showed in vitro inhibition with above 50% inhibition when compare with rhizospheric bacteria. Therefore, it can be concluded that the in vitro biocontrol efficacy was higher in endophytic bacteria over rhizospheric ones.
