Abstract: Disease means disfunction of normal physiological processes in plants caused by microorganisms (or) an abiotic factor. Pathogen means an agent that causes infection. The attribution of the hosts that reduce the chances of infection (or) the further development of the pathogen are considered to be defense mechanism. Defense mechanism in plants can be done by Elicitors. Elicitors are the chemicals (or) bio-factors from various sources that can trigger physiological and morphological responses and also phytoalexin accumulation in the target living organisms. These elicitors may be present in plants and also produced synthetically.
