In 1884, Koch published four postulates that summarized his method for determining whether a particular microorganism was the cause of a particular disease: Each of Koch’s postulatesrepresents a criterion that must be met before a disease can be positively linked with a pathogen.

Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). 1. Dr. Sindhu K., Asst. Pathogenesis is the stage of disease in which the pathogen is in intimate association with living host tissue. The objectives of the Plant Pathology are the study on: i. the living entities that cause diseases in plants; ii. Recently, the journal Molecular Plant Pathology considered which viruses would appear in a Top 10 of plant viruses based on their perceived importance, scientifically or economically, in terms of the views of the contributors to the journal (Scholthof et al., 2011).This was followed by a similar review on fungi (Dean et al., 2012).
