Book Description
Rationale and concepts of crop loss assessment for improving pest management and crop protection. Measurement of disease and pathogens. Measurement of insect pest populations and injury. Modeling of crop growth and yield for loss assessment. Disease progress curves, their mathematical description and analysis to formulate predictors for loss equations. Sampling theory and protocol for insects. Methods of field data collection and recording in experiments and surveys. Generating the database for disease-loss modeling.

Book Description
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.
