In Vitro Antagonistic Activity of Soil Bacteria Against Fusarium in Tomato
- The study was carried out the antagonistic activity of soil bacteria isolated from the soil of peanut fields against Fusarium from the infected leaves of tomato in vitro. The infected leaves of tomato were collected from Shan Ka Lay Kyun village, Amarapura Township, Mandalay Region during August 2016. The fungal Fasarium were isolated by using the Potato Dextrose Agar (PDA) medium and identified by their morphology, colony colour and their spores. The soil bacteria were isolated on King's B medium and ATCC 552 medium. A total of 19 strains were obtained and identified as Bacillus and Pseudomonas by colony color, shape, margin, cell morphology and biochemical tests. Nineteen soil bacteria are MZ 1, MZ 2, MZ 3, MZ 4, MZ 5 MZ 6, MZ 7, MZ 8, MZ 9, MZ 10, MZ 11, MZ 12, MZ 13, MZ 14, MZ 15, MZ 16, MZ 17, MZ 18 and MZ 19. The bacterial isolates were screened for their antifungal activities. The assay for antagonism was performed on Potato Dextrose Agar (PDA) medium by Dual Culture Method. Among the isolated bacterial strains, Pseudomonas MZ 16 showed the most active antifungal activities against Fusarium fungi followed by MZ 17.
