It has been well documented that antimicrobial compounds are abundantly present in medicinal plants (Fiori et al., 2000; Ghosh et al., 2002). These compounds are thought to be involved in defense of plants against microbial pathogens in addition to their direct antimicrobial activity. Ranasinghe et al. (2003) reported that spraying of cinnamon extracts on Embul banana prior to storage, controlled anthracnose and crown rot diseases and also extended the shelf-life of banana fruit. Similarly, Thangavelu et al. (2004) reported that extract from Solanum torvum effectively controlled anthracnose disease and increased the shelf-life of bananas significantly compared to control. In a similar study, Win et al. (2007) reported the efficacy of cinnamon extract, chitosan and hot water treatment in reducing the crown rot disease of banana on a commercial scale.
