Book Description
Potato (Solanum tuberosum L.) is the most important crop and Phytophthora infestans (Mont.) de Bary is the oomycete, which was responsible for infamous Irish potato famine during 1843-45 and it continues to cause worldwide devastation of the potato. Moreover, this disease is re-emerging in the forms of different genotypes and causes huge yield loss in the potato crop. The factors which are responsible for huge yield loss of potato are applied improper management strategies and pathogen behavior. Management strategies includes; forecasting, cultural, biological, varietal and chemical management. Forecasting is the better option for management of late blight, if accurately forecasted and promptly information reaches to the end users. As infected potato tubers cause the primary sources of infection in next season. The cultural practices will also helpful in reducing inoculum load and managing the disease. The host resistance is best option for management of this disease. However, due to very divers' virulence nature of P. infestans; the resistance of the varieties is wiped out within a decade. Several fungicides including contact, systemic and translaminar have been evaluated from time to time; however, the pathogen has shown a remarkable capacity for change with respect to host genotype and fungicides. Nowadays biological control is gaining importance due to its eco-friendly in nature.

Book Description
Excerpt from Late Blight and Rot of Potatoes Caused by the Fungus Phytophthora Infestans (Mont;) De Bary Late blight is unquestionably the most Widely spread and oftentimes the most destructive disease affecting the potato. It is capable of destroying, with remarkable rapidity, the entire growth of the potato plant, and also of causing a very prominent tuber rot. It occurs in practically all potato growing sections of the world and, under favourable circumstances, has caused serious losses.

Book Description
Field experiment was conducted to evaluate the effects of fungicide spray intervals on the control of potato late blight (Phytophthora infestans (Mont.) de Bary) on three potato varieties at Umbulowacho and Hagereselam during the 2010 cropping season from August to December under rain fed condition with natural infection. The study consisted of two released potato varieties Gudene (CIP 386423.13) moderately resistance, Jallene (CIP-384321.19) moderately susceptible and one local variety(Agazer) highly susceptible to late blight, and three Ridomil-MZ 63.5% WP spray intervals 10, 20 and 30days at the rate of 3kg/ha in a randomized complete block design in split plot arrangement with three replications. Varieties were assigned to the main plots and spray intervals to the sub-plots. Disease development started earlier at Umbulowacho (53days after planting) than at Hagereselam (61days after planting). Generally, it was observed that the effects of application of Ridomil-MZ 63.5% at different spray intervals on the tested varieties were found to be highly significant (P

Book Description
Excerpt from Late Blight and Rot of Potatoes Caused by the Fungus Phytophthora Infestans, De Bary These three processes of spore formation, germination and infection can take place only in the presence of sufficient moisture and a suitable temperature. Both spores and swarm spores are quickly killed by drought and sunlight. This partly explains why it is that, although the fungus is present in isolated plants from the time they reach the surface of the ground. It does not spread to any extent until a month, or perhaps two, later. Another reason may be that the plant is more susceptible at and after blossoming time than m its earlier stages.
