PP-308 PLANT DISEASE EPIDEMIOLOGY 3(2-1)

Objective

To study the development of plant disease epidemics.

Intended learning outcomes:

At the completion of the course the students will be able to:

Understand how epidemics are developed.
Understand about the epidemiology of different diseases.
Learn about disease forecasting models, decision support systems and expert systems.

Theory

Introduction, history, importance and types of plant disease epidemics; principles and components of epidemics; factors influencing dynamics of epidemics; global climate change and relationship between climate variation and plant disease epidemics; monitoring of plant disease epidemics; epidemic growth curve and growth rate; forecasting of epidemics and their modeling; disease warning systems.

Practical

Determination of meteorological parameters and their correlation with plant diseases; development of disease prediction models; use of expert systems for monitoring epidemic development; crop loss assessment methods.
