摘要: A plant disease model is a simplification of the relationships (between patho-gen, host plant, and environment) that determine whether how an epi-demic develops over time space. This chapter describes approach for de-veloping mechanistic, weather-driven, dynamic models which are suitable to be applied in precision crop protection. Model building consists four steps: (I) defi-nition purpose; (II) conceptualization; (III) development mathe-matical relationships; (IV) evaluation. Conceptualization based on systems analysis; it assumes state pathosystem can quantitatively determined changes system described by mathematical equations. conceptual (both conceptually mathematically), set driving accounts caused external variables. Two main types described: plant- pathogen-focused models. evaluation judgement overall adequacy model, includes: verification, validation, uncertainty analysis, sensitivity utility. Finally, briefly considers used as tools decision making at different scales space: from warning services agriculture.
