Essay on epidemiology of plant diseases

Abstract Concerns are increasing every day as crops are continuously under threat by various plant diseases worldwide. A sudden epidemic breakout of any plant disease can cause huge economic losses leading towards the famine. To cope with this situation, understanding plant disease triangle and disease epidemic forecasting is very important. So here we have briefly introduced plant disease epidemiology through highlighting its various types by giving important examples. We further have explained the plant disease triangle and disease forecasting systems via inclusion of various models being utilized worldwide. Citation Islam, W.

Hosts and Viruses

History — Plant Pathology

Since the beginning of agriculture, generations of farmers have been evolving practices for combating the various plagues suffered by our crops. Following our discovery of the causes of plant diseases in the early nineteenth century, our growing understanding of the interactions of pathogen and host has enabled us to develop a wide array of measures for the control of specific plant diseases. From this accumulated knowledge base, we can distill some general principles of plant disease control that can help us address the management of new problems on whatever crop in any environment. One such set of principles, first articulated by H. Whetzel in and modified somewhat by various authors over the years, has been widely adopted and taught to generations of plant pathology students around the world. These "traditional principles", as they have come to be known, were outlined by a committee of the US National Academy of Sciences, While these principles are as valid today as they were in , in the context of modern concepts of plant disease management, they have some critical shortcomings.

Plant Disease Epidemiology: An Introductory Lecture by K. M. Golam Dastogeer

Students are required to write papers and essays on epidemiology topics when pursuing academic programs in disease and health conditions. But, what is epidemiology? Well, epidemiology is defined as the study of the patterns, distribution, and determinants of disease and health conditions in a certain population.
We have been lamenting with ecological colleagues while sheltering in place and communicating remotely how we used to feel important as plant ecologists studying global climate change. Currently, however, we feel much less important than the human epidemiologists, health care and other front-line workers who are the heroes during the COVID global pandemic. The discipline of plant ecology has much to offer and much to learn from the epidemiological crisis that we are currently in. Certainly, students will probably pay more attention than before when we drone on about exponential growth and R 0 in ecology lectures in the future.
