Abstract:
The formulation of a biological control agent for plant pathogens is essential to its commercial success. Two potent Bacillus spp. from rhizosphere of healthy watermelon plants with potent antifungal activity against Fusarium spp. were used to prepare bioformulations. In this study, shelf life of the talc based bioformulation of Bacillus subtilis B1 and Bacillus cereus B3 isolates was observed for one year at different storage temperatures viz 30 °C, 25 °C, 15 °C and 5 °C in various packing materials like polythene, cloth and paper bags. There was a gradual decrease in the shelf life of Bacillus bioformulation in different storage conditions. The cfu of bioformulation decreased less at 5 °C storage temperature as compared to bioformulation which were stored at 30 °C temperature.
