    abstract = {Potato (<i>Solanum tuberosum </i>L.) is the fourth  major crop of the world after rice, wheat and maize.  Ethiopia has possibly the highest potential for potato  production of any country in Africa. However in Ethiopia,  the yield per unit area of potato is very low compared to  those of other countries. There are many factors that  reduce the yield of the crop among which the diseases like  late blight (<i>Phytophthora infestans</i>), early blight  (<i>Alternaria solani</i>), bacterial wilt (<i>Ralstonia</i>  <i>(Pseudomonas) </i>solanacearum) and Viruses are play an  important role. Hence, the objective of this paper is to  review the major potato diseases and some major attempt  done to overcome the challenges of diseases in potato  growing regions. Bacterial wilt is caused by a pathogen  that isn&rsquo;t easily managed. There is need for more research  on the epidemiology and the host-pathogen interaction in  order to devise the most appropriate management  strategy. Late blight of potato, caused by Phytophthora  infestans (<i>Mont. De Bary</i>) is among its most important  diseases, being especially, devastating in the major potato  growing areas. Serious economic consequences often  result from complete or partial devastation of infected  fields. In Ethiopia the disease caused 100% crop loss on  unimproved local cultivar and 67.1% on a susceptible  variety. Integrated management of late blight through the  use of resistant potato clones, fungicides and cultural  measures appear to offer the best option for disease  management in the tropical highlands of Africa. As  potato is propagated by vegetative means, virus  diseases could easily disseminate and accumulate in  tubers causing degeneration of varieties and  subsequent reduction in potato tuber yield. Potato  viruses such as PLRV, PVY and PVX are the major  causes for degeneration of varieties. Since, there is no  viricide available the damage due to viruses can be  minimized by managing host genotype and cultural  practices. Therefore, adopting Integrated Disease  Management (IDM) approach is the most effective,  environmentally safe and low costly to the users.}
