Liquid formulation of Bacillus subtilis-KK-9A, Brevibacillus borstelensis-BK-6, Brevibacillus sp-PM-2A, Lysinibacillus xylanilyticus-VK-6B and consortium were developed using distilled water, ground nut oil, nutrient broth, pongamia oil and sunflower oil to enhance the shelf life and efficacy of the biocontrol agent besides easing the delivery of bio-inoculants through micro-irrigation techniques. The highest population level of Bacillus subtilis-KK-9A, Brevibacillus borstelensis-BK-6, Brevibacillus sp-PM-2A and Lysinibacillus xylanilyticus-VK-6B were observed in pongamia oil amended with glycerol even after 3 months of storage. Pongamia oil based formulation was found best formulation followed by ground nut oil, sunflower oil, distilled water, nutrient broth based formulation which retains the highest per cent survival of Bacillus subtilis (45.05), Brevibacillus borstelensis (32.93), Brevibacillus sp (48.80), Lysinibacillus xylanilyticus (60.80), and consortium 31.12 per cent even after 90 days.
