Plant disease epidemiology is the study of the distribution and spread of plant diseases, and there are many synonyms for this field of research. Some alternative terms include plant pathology, plant health, plant disease ecology, disease management, and agro-epidemiology. Each of these phrases captures a slightly different aspect of the study of plant disease, from the biology of pathogens to the practical implications of disease spread on crops. Plant disease epidemiology is a critical area of research for the agricultural industry, as it helps to prevent and manage outbreaks that can have devastating effects on crop yields and food security.
