In this paper the construction of a detailed, discrete deterministic simulation model coupling the development and spread of a fungus Erysiphe necator, with the development of its host, the perennial crop Vitis vinifera, isdescribed. The model was used to show, by simulation, the dependence of epidemic development on climatic variables and crop management parameters. The model was designed to (i) quantify and rank the most important host and pathogen factors that modify the dynamic interactions between pathogen, host and their environment and, (ii) simulate the spatiotemporal dynamics of host growth and epidemic development, beginning from a
range of climatic conditions, production systems and initial conditions for the density and location of the pathogen, in order to identify situations most conducive to the spread of disease.
