Isolation and Characterization of Phylloplane Associated Bacteria and its in vitro Antagonistic Activity against Bipolaris oryzae
نویسندگان
چکیده
Background: Rice brown leaf spot is a major fungal disease caused by Bipolaris oryzae. Biological management of can be achieved bacteria associated with phyllosphere region rice crop. Methods: Antagonistic were isolated from phylloplane the crop using dilution method. Phylloplane morphologically and biochemically characterized. activity was tested against oryzae Dual culture technique. Result: Among isolates, PB1, PB3, PB6, PB7, PB9 identified as Pseudomonas fluorescens PB2, PB4, PB5, PB8, PB10 Bacillus subtilis morphological biochemical characterization. PB5 showed maximum inhibition B. mycelium (70.00%) followed PB1 (67.77%). Minimum mycelial growth (31.11) found in PB9.

In vitro antagonistic action of egg plant and sweet potato phylloplane bacteria to some parasitic fungi
The surfaces of aerial plant parts provide a habitat for epiphytic micro-organisms, many of which also influence the growth of pathogens. Bacteria are generally the predominant initial inhabitants of newly expanded leaves, while yeasts and filamentous fungi dominate later in the growing season (Kinkel et al., 1987). A large body of information has been accumulated regarding antagonism between b...
