Title : Weather Based Prediction Of Early Blight Of Potato Caused By Alternaria Solani

Abstract :

Epidemiological studies conducted during rabi season of 2018-20 to study the progression of early blight of potato in relation to weather parameters such as, maximum temperature, minimum temperature, maximum relative humidity, minimum relative humidity and rainfall. The initial infection of early blight occurred during 51th Standard Meteorological Week (SMW), with maximum infection rate of 0.094 during 2nd SMW. Maximum and minimum temperatures had significantly positive correlation with the intensity of early blight, whereas, minimum relative humidity had significantly negative correlation. Stepwise multiple linear regression equations revealed that maximum temperature, maximum and minimum relative humidity was responsible for 97.08 contribute for early blight of potato.
