Biochemical Characterization of Xanthomonas axonopodis pv. malvacearum Isolated from Infected Cotton Plant and It’s in vitro Sensitivity against Some Selected Chemicals | Chapter 10 | Current Research in Science and Technology Vol. 3
Aim: The aim of our study is to isolate, identify and pathogenicity test of Xanthomonas axonopodis pv. malvacearum (Xam) causing bacterial blight of cotton and to determine the comparative efficacy of some selected chemicals and antibiotic in controlling Xam in vitro. Place and Duration of the Study: This study was carried out at the Department of Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh from January, 2012 to December, 2013. Methodology: Xanthomonas axonopodis pv. malvacearum was isolated from infected leaves, stems, branches, cotyledons and bolls of cotton. Biochemical characterization and in vitro sensitivity were evaluated as per the standard methods as described in materials and methods. Results: The bacterium was gram negative, rod shaped and showed positive results in KOH solubility, starch hydrolysis, catalase, citrate utilization, motility indole ureas agar (MIU), gelatin liquefaction test and oxidase test. It produced, slightly r...
