Objective
The objective of the course is to deal with the interrelationships between plants and pathogens under the influence of meteorological conditions (environment) and the man action through crop management. To this end, topics such as plant disease epidemiology, plant-pathogen-environment interrelationships, geophytopathology and zoning of disease escape areas, disease growth models, yield loss models and plant disease warning systems will be addressed.

Content
1) Notions of epidemiology and phytopathometry - Diagrammatic scales of disease evaluation. Disease progress curves and mathematical models for their fit. 2) Host Phenology - Phenometry. 3) Pathogen-Host-Environment Interrelationship - Influence of weather and climate on fungal epidemiology. Macro, meso and microclimate. Weather variables and plant diseases. 4) Geophytopathology - Use of maps. Planning of crop protection. 5) Microclimate and occurrence of diseases - Energy balance in leaves. Microclimatic characteristics of crops. Effect of irrigation and other agricultural practices on the microclimate. 6) Weather sensors for use in epidemiology - Temperature. Relative humidity and leaf wetness duration. Wind. Automatic data acquisition systems. 7) Measurement and estimation of leaf wetness duration. 8) Prediction models of disease occurrence - Host growth models. 9) Challenges of modeling plant diseases. 10) Forecast of crop yield losses caused by diseases. 11) Plant disease warning systems - Basic concepts and applications. 12) Analysis of the climatic risk associated with the occurrence of plant diseases.
