Abstract :

 Mango bacterial canker disease (MBCD) caused by Xanthomonas campestris pv. mangiferaeindicae (Xcmi) is one of the important diseases of mango affecting a number of commercial cultivars. The pathogen affects different plant parts like leaf, stem and fruit. Favorable environmental conditions cause severe loss to the crop. Leaf extract of various plants were tested against Xcmi for antibacterial activity. Azadirachta indica is well known for its antimicrobial activity. Hence, leaf extracts of A. indica assessed for its antibacterial activity against 25 strains of Xcmi collected from different parts of Marathwada region of Maharashtra. In vitro studies have been performed by using cup–plate method to examine the activity. Fresh leaf extracts of A. indica plants were screened against 25 strains of Xcmi. The maximum activity was recorded against Xcmi.09 (Mean activity zone – 21.86 mm) followed by Xcmi.07 (Mean activity zone – 21.55 mm) and minimum against Xcmi.23 (Mean activity zone – 18.30 mm) strain under investigation. The ultimate aim of the research work was to develop economically and technically viable field formulations for the farmers, which will be Bio–ecologically compatible for management of plant bacterial diseases.
