Plant disease epidemics result from the interaction of a population of pathogens and susceptible plants influenced by the environmental conditions. In this context, a simple and operational definition of epidemics can be “the change of the intensitiy of the disease in a population of plants in time and space” (Madden et al., 2007).
Hence, studies that aim to understand the factors and mechanisms that affect epidemic processess and its dynamics over space and time are under the scope of botanical or plant epidemiology, or plant disease epidemiology. Research in our laboratory is focused on the basic understanding of risk factors that lead to epidemics in plants and their impact in both crop production and food security in order to develop rational management strategies. For such, holistic approaches that combine information from the molecular to landscape level are used to integrate knowledge on the epidemics.
