Agri disease models
Grape
Grape vine downy mildew caused by Plasmapora Viticola is an important weatherrelated disease that can potentially cause heavy losses in production quality and quantity each year and especially serious in climates with high rainfall and high relative humidity imparting long period of leaf wetness.
Disease management generally requires frequent use of fungicides applied several times during the growing season. High cost due to frequent applications of fungicide and the desire to reduce pesticide levels in the environment have motivated considerable efforts to develop disease prediction or warning systems. Agro meteorological variables i.e. Air Temperature, Air Humidity and Leaf Wetness Duration (LWD) are known to be the parameters, which strongly influence the disease development.
Potato
Late blight caused by Phytophthora infestans is a devastating disease of potato which during certain years assumes epiphytotic proportions causing huge loss to the seed and ware potato crop.
Worldwide potato crop losses due to late blight have been estimated at € 12 billion (Haverkort et al.,2009). Forecasting appearance of the disease in advance can greatly help potato farmers to take prophylactic sprays and prevent or delay appearance of the disease and thus reduce the losses. Weather conditions such as temperature, relative humidity, rainfall, dew, sunshine hours etc. have a direct effect on P. infestans (De Weille, 1963). These parameters have been exploited to develop different models to forecast the disease both in India and elsewhere.
