Experimental Techniques In Plant Disease Epidemiology

Most books on epidemiology have treated the subject from a statistical, mathematical or computer applicational point of view. However, experiments must be performed first to provide the data for models which in turn can then be proven by further experimentation. This mutual interplay of theory and empirics gives epidemiology its scientific thrust and charm. This book provides a choice of methods for varying applications and objectives, covering all important aspects for the designing of experiments. Furthermore, the reader is supplied with solutions to his experimental problems and many "tricks of the trade". The newcomer to the field will also profit by this methodology guide.

Development of plant disease epidemiology, monotoring epidemics: host, environment, pathogen and disease. Modeling and data analysis. Temporal analysis of epidemics: description and comparison of disease progress curves and advaced topics. Spatial aspects of plant disease epidemics: dispersla gradients and long-range transport and analysis of spatial pattern-simulation models of plant diseases, designings experiments and smapling, crop loss assessment and modeling and forecasting plant disease.

In this volume experts present the latest status of mathematical and statistical methods in use for the analysis and modeling of plant disease epidemics. Topics treated are - methods in multivariate analyses, ordination and classification, - modeling of temporal and spatial aspects of air- and soilborne diseases, - methods to analyse and describe competition among subpopulations, e.g. pathogen races and - their interaction with resistance genes of host plants - assemblage and use of models - mathematical simulation of epidemics. New chapters on the modeling of the spreading of diseases in air and in soil are included in this second edition.

Plant disease epidemiology is a dynamic science that forms an essential part of the study of plant pathology. This book brings together a team of 35 international experts. Each chapter deals with an essential component of the subject and allows the reader to fully understand how each exerts its influence on the progress of pathogen populations in plant populations over a defined time scale. This edition has new, revised and updated chapters.

Plant Diseases: Epidemics and Control provides a description of the methods of epidemiological analysis based on infection rates and the relation between the amount of inoculum and the amount of disease it produces. The book shows how to study the increase of pathogen populations and the epidemiological strategy to be adopted to control the epidemic of plant diseases. The text covers the calculation of the logarithmic increase of disease; use of epidemiology in the study of control; forms of sanitation; the use of resistant plant varieties; and the design of field experiments. Plant pathologists and breeders, agriculturists, horticulturists, research workers, teachers, and students will find the text invaluable.

As the global climate changes, plant disease epidemiology faces important questions: Will climate change render plant diseases more harmful to man-made ecosystems, or less? Can sustainable systems be developed in time to spare and enhance shrinking resources? How will changes in host plant diversity affect genetic disease resistance? This book provides an overview of current research in plant disease epidemiology from researchers at the cutting edge of this important discipline.

Plant disease epidemics, caused by established and invasive pathogen species, continue to impact a world increasingly concerned with the quantity and quality of its primary food supply. The Study of Plant Disease Epidemics is a comprehensive manual that introduces readers to the essential principles and concepts of plant disease epidemiology.
