The frequently changing of ecological condition demands for developing ecofriendly herbal antimicrobial agents. The present study was under taken to evaluate the antimicrobial activity of ethanolic leaf extract of Neem leaf and flower extracts of Nochi against phytopathogens, Xanthomonas and Fusarium. All plant extracts showed considerable antibacterial activity against Xanthomonas and antifungal activity against Fusarium. The results showed that the leaf extract of Neem had high toxicity against tested pathogenic organisms, the antimicrobial activity of other extract increases with increasing concentration of extracts.
