Some of these chemicals displayed the potential of antimicrobial activity. Similarly, Lauren et al. (2011) demonstrated that saponin, one of preformed chemicals, from cereal exhibited the ability of microbial suppression. Furthermore, Prusky (1996) reviewed that preformed substances in plant tissues such as diene extracted from pericarp of avocado fruit can affect latent infection by suppressing pathogen growth. Although, antifungal substances in plant tissues
