PL PATH 518 EPIDEMIOLOGY AND FORECASTING OF PLANT DISEASES (2L+1P) III
To provide knowledge with the principles of epidemiology and its application in disease forecasting.
Epidemic concept and historical development, pathometry and crop growth stages, epidemic growth and analysis.
Common and natural logrithms, function fitting area under disease progress curve and correction factors, inoculum dynamics, population biology of pathogens, temporal spatial variability in plant pathogens.
Survey, surveillance and vigilance, crop loss assessment and models.
Principles and pre-requisites of forecasting, systems and factors affecting various components of forecastings, some early forecasting, procedures based on weather and inoculum potential, modeling disease growth and disease prediction.
Measuring diseases, spore dispersal and trapping, weather recording, survey, multiplication of inoculum, computerized data analysis, function fitting, model preparation and validation.
