Plant disease epidemiology is the study of disease in plant populations. Much like diseases of humans and other animals, plant diseases occur due to pathogens such as bacteria , viruses , fungi , oomycetes , nematodes , phytoplasmas , protozoa , and parasitic plants . [ 1 ]
Zadoks developed what is arguably the world's first course on plant disease epidemiology with a wet lab and field practical. He pioneered courses in 'Aerobiology', 'Crop Loss', 'Genetics of Resistance' and 'Plant Protection and Society'. The first course formed the basis of the textbook 'Epidemiology and plant disease management'. [4]
Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Organisms that cause infectious disease include fungi , oomycetes , bacteria , viruses , viroids , virus -like organisms, phytoplasmas , protozoa , nematodes and parasitic plants . [ 2 ]
Plant disease triangle. Epidemiology is the study of factors affecting the outbreak and spread of infectious diseases. [10] A disease triangle describes the basic factors required for plant diseases. These are the host plant, the pathogen, and the environment. Any one of these can be modified to control a disease. [11]
Plant Disease is a peer-reviewed scientific journal of plant pathology focusing on new diseases, epidemics, and methods of disease control. It is a continuation of The Plant Disease Bulletin (1917–1922) and The Plant Disease Reporter (1923–1979), both publications of the US Department of Agriculture . [ 1 ]

This disease results in reduced yield in crops, a withered appearance of the leaves, abortive reproductive structures, and a grayish down on the surfaces. Historically, there have been cases of epidemics in which the species infected cultivars of maize and sugarcane and decimated the populations, causing up to $23 million US dollars’ worth of ...
