The antagonistic potential of bacteria is being applied to biocontrol the infectious diseases caused by pathogenic fungi in plants that are one of the major threats to the growth and productivity of crop plants. In the present study, bacterial strains were isolated from soil samples collected from the rhizosphere of Sorghum (Sorghum bicolor) and Wheat (Triticum aestivum). Microscopic analysis revealed that all three bacterial isolates were Gram-positive, rod-shaped and spore-forming. The isolates Bacillus subtilis BP171 and Bacillus amyloliquefaciens BP124 demonstrated salt tolerance up to 12% while Bacillus subtilis BP67 tolerated up to 10% of NaCl. All the three strains were screened against seven test pathogenic fungi like Bipolaris sorokiniana, Fusarium oxysporum, Aspergillus sp., Penicillium sp., Rhizoctonia solani, Aspergillus niger, and Fusarium sp. for their antagonistic activity. BP124 was found to be the most potent in comparison to BP67 and BP171. Bacillus amyloliquefaciens BP124 demonstrated significantly highest (p
