A total of 19 onion samples out of 206 collected samples showing 0-22.22% disease incidence in seven blocks of Alwar district were isolated. These isolated bacterial colonies were subjected to morphological, cultural and biochemical tests for characterization and identification. On the basis of various experimental tests performed the isolated bacterial colonies were identified as Pseudomonas aeruginosa.
