Abstract

In epidemics of downy mildews, the pathogen population starts from a low level of initial inoculum which then increases exponentially through successive cycles on the host during the growing season. The seasonal increase of the pathogen population has been investigated much more thoroughly than that of the initial inoculum. Information has been generated on the multiplication phase of the disease, which relates to the sequence of events in the life of the pathogen on its host, which are infection, colonization, and sporulation. The studies on forecasting of crucifers’ downy mildew disease are limited to prediction models.
