Among major food crops, potato occupies fourth position following rice, wheat and maize across the globe. There are several factors affecting the crop yield and quality in potato of which disease is one of the most important factors. Potato diseases are caused by fungi resulting in the immense economic loss, posing the threat to food security and sustainable agriculture. Therefore, effective disease management is essential to overcome these risks. In this review, the objective is to discuss the disease causing pathogen, symptoms, factors favouring disease and integrated management of early blight, late blight, black scurf and wart diseases. The famous Irish famine disease i.e. late blight is a major challenge in potato, which can be controlled with the help of intercropping. In addition to late blight, other major complex diseases mentioned above can cause significant potato yield loss. Pathogen survival in soil prohibits the sustainable potato production in same field. However, as new strain develops, no management practice is effective when used alone. Therefore, integrated disease management approach i.e. chemical control in combination with bio-control agents, is the most efficient, cost effective and eco-friendly way to effectively combat pathogens. For complex diseases, the common control measures employed worldwide include the use of tolerant cultivars, crop rotation and other practices; singly or collectively have met limited success. Therefore, there is a dire need of extending research for disease management in potato for better food quality.
