Since its creation in 1920, The International Mycological Institute has been concerned with the identification of plant-pathogenic fungi and bacteria. Part of its role has been the development of plant clinics, which have an important role in providing access for farmers and extension workers to specialist scientific services for the diagnosis of plant disease problems and advice on control measures. Clinics can also be bases from which surveys of crop problems are made and data on the needs of farmers are assimilated, in order to identify research priorities. This practical handbook provides information on all aspects of the technical procedures, material requirements and organization for the effective operation of a plant clinic. It describes the diagnostic process, from field observation and collection through to methods of culture, microscopy, keeping records and reference material, general laboratory practice and equipment maintainance. The procedures described have been used successfully at IMI for many years, and through a series of training programs, have been transferred to laboratories in many other countries. Essential reading for those involved in setting up and running plant clinics and plant quarantine facilities, this handbook will also be of interest to all practitioners and advanced students of plant pathology, particularly those concerned with diagnostics, and to crop protection specialists working in an advisory capacity.

Our dependence on healthy vegetable crops as a reliable source of food transcends all barriers of nation and culture. Consumers now demand excellent quality from the industry that produces large volumes of high quality vegetables to be sold locally, regionally and shipped internationally. The diseases that affect vegetables compromise such quality

This work provides information on the detection, identification, and differentiation of all microbial plant pathogens - presenting modern protocols for rapid diagnosis of diseases based on biological, physical, chemical and molecular properties. It contains methods for the selection of disease-free seeds and vegetatively propagated planting materials and quarantine techniques for screening newly introduced plant materials.

Revised and updated with new concepts, case studies, and laboratory exercises, Plant Pathology Concepts and Laboratory Exercises, Second Edition supplies highly detailed and accurate information in a well-organized and accessible format. New additions to the second edition include five new topic and exercise chapters on soilborne pathogens, molecular tools, biocontrol, and plant-fungal interactions, information on in vitro pathology, an appendix on plant pathology careers, and how to use and care for the microscope. An accompanying cd-rom contains figures from the text as well as supplemental full-color photos and PowerPoint slides. Unique Learning Tools Retaining the informal style of the previous edition, this volume begins each topic with a concept box to highlight important ideas. Several laboratory exercises support each topic and cater to a wide range of skill sets from basic to complex. Procedure boxes for the experimental exercises give detailed outlines and comments on the experiments, step by step instruction, anticipated results, and thought provoking questions. Case studies of specific diseases and processes are presented as a bulleted list supplying essential information at a glance. Comprehensive Coverage Divided into six primary parts, this valuable reference introduces basic concepts of plant pathology with historical perspectives, fundamental ideas of disease, and disease relationships with the environment. It details various disease-causing organisms including viruses, prokaryotic organisms, plant parasitic nematodes, fungi, plant parasitic seed plants, and other biotic and abiotic diseases. Exploring various plant-pathogen interactions including treatments of molecular attack strategies, extracellular enzymes, host defenses, and disruption of plant function, the book presents the basic ideas of epidemiology, control strategies, and disease diagnosis.
