Simulation of epidemics caused by Venturia inaequalis (Cooke) Aderh

, : Simulation of epidemics caused by Venturia inaequalis (Cooke) Aderh. EPPO Bulletin 9(3): 235-242

Simulation of apple scab epidemics based on analog computer models, multivariate regression analyses, and systems analyses is discussed. Details of underlying models and their scope for applications are emphasized. Monomolecular growth functions by Bertalanffy and Gompertz in analog computers permit fast simulation of disease progress curves. The models derived from multivariate analyses of field experiments on apple scab epidemics closely simulate the changes in infection rates. EPIVEN, a comprehensive and self-generating simulator of apple scab epidemics is reviewed and compared to a reduced model, also based on elements of the system, apple scab epidemic.
