In recent years, Bioinformatics plays an essential role in today’s plant pathology with regards to the development of new plant diagnostic tools. Pathogen is among the traits considered in the primary interest of plant bioinformatics. The contribution of bioinformatics advances made possible the mapping of the entire genomes of many organisms in just over a decade. Bioinformatics have many practical applications in current plant disease management with respect to the study of host-pathogen interactions, understanding the disease genetics and pathogen city factor of a pathogen which ultimately help in designing best management options
