Late Blight Forecast Using Mobile Phone Based Agro Advisory System

The late blight disease is the most common disease in potato, which is caused by the pathogen Phytopthora infestans. In this paper, a novel method to collect symptoms of the disease, as observed by the farmers, using a mobile phone application has been presented. A cumulative composite risk index (CCRI) obtained from more than one existing disease forecast models is validated from the actual late blight queries received from the farmers. The main contribution of the paper is a protocol that combines the symptoms based diagnostic approach along with the plant disease forecasting models resulting in detection of Potato late blight with higher accuracy. This in turn reduces the disease risk along with avoiding the unnecessary application of fungicide.
