Soil borne pathogens cause a significant economic losses in agricultural production all over the world. The disease caused by these pathogens are difficult to predict, detect, diagnose and successfully control. A sustainable management approaches are very important to minimize the activity of these pathogens. There are various method to manage the soil borne pathogens such as cultural methods, physical methods, chemical methods, biological methods and growing a resistant varieties. The effective control of the soil borne pathogens is possible only through detailed study on survival and dissemination of these pathogens. Effect of environmental conditions, role of cultural practices and host resistance and susceptibility will play a major role in disease management.
