Abstract:

Late blight caused by Phytophthora infestans (Mont.) de Bary has been recorded as one of the devastating disease and is considered as one of the limiting biotic factor for potato cultivation. The study pertaining to Aerobiology of Phytophthora infestans revealed that the aerial concentration of sporangia decreased progressively with height above the pant canopy, the highest concentration of spores was registered during Kharif (0-59.93/week) compare to Rabi (0-30.79/week). Rainfall, relative humidity and minimum temperature showed positive correlation while maximum temperature and evapotranspiration had negative correlation with spore load. Under field conditions, disease was affected by variation in weather variables, as cool temperature (16-23℃) and wet weather coincides with high relative humidity (>90%) and rainfall of 1.5-4.2mm favored the disease progression.
