Abstract : Mango bacterial canker disease (MBCD) caused by Xanthomonas campestris pv. mangiferae indicae (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. The in vitro studies have been performed by using cup-plate method to examine the antibacterial activity of some seed extracts. Seed extracts of 6 plants were screened against 11 strains of Xcmi. Out of 6 seed extracts, 4 seed extracts showed antibacterial activity. The seed extract of Brassica juncea showed maximum activity; while Cyamopsis tetragonoloba showed minimum antibacterial activity against the Xcmi strains under investigation.
