The incidence of Alternaria blight caused by Alternaria porri largely depends on meteorological parameters, location, cultivars susceptibility and cultural practices. Change of climate affects the disease incidence. Co-relation of meteorological parameters on the natural occurrence of Alternaria blight was studied from 21/11/2012 to 19/03/2013 in sixteen meteorological weeks under field condition at experimental plot, Dept. of plant pathology, OUAT, Bhubaneswar. The weather factors such as maximum and minimum temperature (0C), maximum and minimum relative humidity (%), rainfall (mm), number of rainy days (days), wind velocity(km/hr) contributed about 70.2% towards the disease incidence. However, the parameters like maximum temperature, maximum RH, number of rainy days and wind velocity were found statistically significant with respect to disease development.
