Résumé
Dexi version of ExpeRoya model. The model structure is a tree that aggregates variables in a hierarchical way according to available knowledge on coffee leaf rust (CLR) and coffea arabica (the host) dynamics. ExpeRoya integrates 229 multiple interactions that exist within the CLR-coffee pathosystem based on 12 input variables: one incidence monitoring variable; two meteorological variables (temperature and rainfall), four crop management variables (management of shade cover, fungicide application, nutrition and pruning of coffee trees) and five coffee tree characteristics (dates of flowering, beginning and end of harvest, fruit load and cultivar genetic resistance).
