Controlling Cyclic Epidemics on the Crops of the Agroecosystems: Articulate all the Dimensions in the Formalisation, but Look for a Local Solution

Figure 1

Schematic representation of the four types of disease dynamics given the initial presence of the disease and the suitability of the climate. When the climate is suitable continuously, initial absence or presence of the disease contrasts: (a) epidemic and (b) endemic, respectively. When the increase of the disease is discontinuous on short-term time scale, dynamics over long-term time scale contrasts: (c) polyetic epidemic and (d) cyclic epidemic, respectively.
