Pathogenecity in Plants

Any abnormal condition that alters the appearance or function of a plant is referred as Plant Disease. The major cause of plant disease is pathogens that affect plants that results in reduced yield and quality of harvested product. Any detectable changes in color, shape, and/or functions of the plant in response to a pathogen or disease-causing agent is a symptom. Plant Pathogen is a parasitic organism such as fungi, bacteria, virus, Nematodes that cause disease in plants. Pathogen extracting nutrients by invading plants is referred as host.
