Description
Summary:Colletotrichum falcatum and Fusarium moniliforme are the causal agents of red-rot and pokkah boeng disease in sugarcane respectively, which are among the most destructive diseases in this crop worldwide. In this work, antifungal property of bacteria was evaluated against these two plant pathogenic fungi. Initially six bacterial strains were screened by dual culture technique and two strains Bacillus cereus MTCC 9017 and Pseudomonas monteilii MtCC 9796 were selected for further studies. Ethyl acetate extracts of culture filtrates of these two bacteria were obtained and assayed for antifungal potential by poisoned food method. Both of the bacterial isolates tested showed significant antifungal activity against Colletotrichum falcatum and Fusarium moniliforme. The results of this study indicate the possibility of further exploring B. cereus MTCC 9017 and P. monteilii MTCC 9796 as potential biocontrol agents.
