Abstract

Citrus canker caused by Xanthomonas citri sub. sp. citri is important and devastating disease causes huge economical losses tocitrus industry. Pathogen was isolated from the infected leaf from different acid lime orchards in the present study.Experiment was conducted to screen out the virulent isolate with compatible host and pathogen combination in acid lime and canker causing pathogenic culture of X. citri sub. sp. citri. This compatible combination was tested under controlled environment condition using pinprick method. Among the 10 isolates collected from acid lime growing areas of northern Karnataka, isolate Xac8 was found to be the most virulent followed by Xac5. Studies were conducted to evaluate antibiotics/ antibacterial chemicals against the two highly virulent isolates of X. citri sub. sp. citri by inhibition zone assay method.
