The Measurement and Analysis of the Effects of Crop Development on Epidemics

  • Robert C. Seem


The above quotation is a plain indictment of plant epidemiologists who confine their interests to the dynamics of pathogen populations while failing to consider the equally important dynamics of host populations. Many scientists, who study epidemics of plant diseases, are first trained as plant pathologists with primary emphasis on the pathogens causing diseases. Consequently, epidemiological studies by plant pathologists often consider the dynamics of the pathogen under static crop conditions. Yet the host is as dynamic as each of the other two members of the plant disease triumvirate, the pathogen and the environment.
