Plant Disease Models
A plant disease model is a mathematical description of the interaction between environmental, host, and pathogen variables that can result in disease. A model can be presented as a simple rule, an equation, a graph, or a table. The output of a model can be a numerical index of disease risk, predicted disease incidence or severity, and/or predicted inoculum development.
