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. Favourable environmental conditions cause severe loss to the crop. Leaf extracts of various plants are known to possess antimicrobial activity. The in vitro studies have been performed by using cup-plate method to examine the antibacterial activity of some leaf extracts. Fresh leaf extracts of 30 plants were screened against 11 strains of Xcmi. Out of 30 leaf extracts, 12 leaf extracts showed antibacterial activity. The extract of Terminalia thorelii and Azadirachta indica showed maximum activity against the Xcmi strains under investigation.
