Plant Nematodes

Plant-parasitic nematodes are recognized as one of the greatest threats to crop production throughout the world. Estimated annual crop losses of $8 billion in the United States and $78 billion worldwide are attributed to plant parasitic nematodes. Plant parasitic nematodes not only cause damage individually but form disease-complexes with other microorganisms thereby increasing crop loss. Nematode diseases of crops are difficult to control because of their insidious nature and lack of specific diagnostic symptoms which closely resemble those caused by other plant pathogens and abiotic diseases. Future developments of sustainable management systems for preventing major economical agricultural losses due to nematodes is focused on strategies that limit production costs, enhance crop yields, and protect the environment. This book presents a first compendium and overview for nematode problems and their management across North America. Each chapter provides essential information on the occurrence and distribution of plant parasitic nematodes, their major crop hosts, impact on crop production and sustainable management strategies for each region of the continent including, Canada, Mexico and all states of the USA. For each region, a thematic overview of changes in crop production affected by plant parasitic nematodes and their management strategies over time will provide invaluable information on the important role of plant parasitic nematodes in sustainable agriculture.

This book contains 22 chapters, 2 appendices (of the nematicides and species mentioned throughout the book) and 24 colour plates covering all aspects of practical plant nematology in subtropical and tropical agriculture, including rice, cereals, sweet potatoes, root and tuber crops, food legumes, vegetables, groundnut, citrus, tree and fruit crops, coconut and other palms, coffee, cocoa, tea, bananas, sugarcane, tobacco, pineapple, cotton, other tropical fibres, spices and medicinal plants. It provides practical guidance on the methods of extracting, processing and diagnosing different plant and soil nematodes and on integrated nematode management. This book is intended for those studying and working in the area of crop protection.

Plant Parasitic Nematodes, Volume III provides a comprehensive discussion of the different advances in plant nematology. This includes biochemical techniques to taxonomy and innovation in transmission and scanning electron microscopy technology. It explains a broadened basis for understanding nematode physiology and behavior and the sensory mechanisms that govern nematode actions and plant host-nematode interactions. The book discusses the development of modern approaches to the evaluation and reduction of crop losses. The emphasis of this volume is on plant parasites and insights gained through research on other nematodes. In particular, the book explains the anatomical, developmental, behavioral, and genetic studies on the free-living nematode Cenorhabditis elegans, which is a widely used laboratory model for examining various biological problems. The information provided by various researches on C. elegans increases our understanding about the relevance of nematodes to general biological processes in higher organisms, including man. The book is divided into 19 chapters which cover the following concepts of plant nematology: biochemistry, cytochemistry, and genetics; morphology and function; host-parasite relations; and evaluation and control of crop losses. The present volume is an excellent reference for students, lecturers, and research professionals in plant parasitology and related fields.

When I conceived this book, what I had in mind was what I did not know about coffee-parasitic nematodes (CPNs). Indeed, after reading many papers and several chapters in books, I felt far from having a comprehensive understanding of the subject. Not only would it be a daunting task to retrieve the numerous articles, reports, theses and dissertations on CPNs published since 1878, but it would also be impossible to learn, on my own, from all the enormous experience acquired by nematologists and coffee growers in so many countries. Therefore, this book is dedicated to those with restless minds, who want to know more about CPNs and their importance in coffee production worldwide. This book has been diligently written by top scientists in their areas of expertise or country, and it has been meticulously edited to guarantee precision without compromising an enjoyable read. I learned a lot from this book...I’m sure you will too. Finally, I’d like to thank Zuzana Bernhart from Springer, who believed in this project and decided to publish it; Susan Casement, who revised all chapters for grammatical correctness; and all the contributors, without whom this book would never have became a reality.

Formerly titled Plant-Parasitic Nematodes: A Pictorial Key to Genera, this volume has been the standard work on plant disease around the globe. Now in its fifth edition, it remains the fundamental reference for students as well as for diagnosticians—a usable, comprehensive key to plant-parasitic nematodes and the only guide to feature both photographs and drawings. Accompanied by full-page plates, the book offers descriptions of 68 genera, including most that have one or more species known to be plant parasites. The bibliography of approximately 2,500 entries on the taxonomy and morphology of nematode genera is one of the fullest on this subject. For the present edition, the authors have made revisions throughout and have added references to more than two hundred genera not previously included. An updated taxonomy, glossary, and an index are also provided. William F. Mai is Liberty Hyde Bailey Emeritus professor, Peter G. Mullin is Coordinator of Laboratory Instruction, and Howard H. Lyon is Biological Photographer (retired) in the Department of Plant Pathology, Cornell University.

Plant-parasitic and free-living nematodes are increasingly important in relation to food security, quarantine measures, ecology (including pollution studies), and research on host-parasite interactions. Being mostly microscopic, nematodes are challenging organisms for research. Techniques for Work with Plant and Soil Nematodes introduces the basic techniques for laboratory and field work with plant-parasitic and free-living soil-dwelling nematodes. Written by an international team of experts, this book is extensively illustrated, and addresses both fundamental traditional techniques and new methodologies. The book covers areas that have become more widespread over recent years, such as techniques used in diagnostic laboratories, including computerized methods to count and identify nematodes. Information on physiological assays, electron microscopy techniques and basic information on current molecular methodologies and their various applications is also included.

Covering all aspects of practical plant nematology in subtropical and tropical agriculture, the third edition of this definitive global reference work is fully revised and in full colour throughout. It covers the presence, distribution, symptomology and management of all economically important plant parasitic nematodes damaging the world's major food and cash crops. This includes: rice, cereals, solanum and sweet potatoes (and other root and tuber crops), food legumes, vegetables, peanut, citrus, fruit tree crops, coconut and other palms, coffee, cocoa, tea, bananas, sugarcane, tobacco, pineapple, cotton, other tropical fibres, spices and medicinal plants. New content for this edition includes: A chapter on nematode soil biodiversity and soil health; Reflections on the future impact of nematodes and nematology on food security; The importance of climate change, emerging threats, and new management technologies for large and small subsistence growers; Significant revisions to the IPM chapter and chapters on vegetables, citrus, legumes, tuber crops, cotton, peanut and banana where major advances in nematode management have occurred. This book is highly illustrated, with up-to-date practical guidance on methods of extraction, processing and diagnosing of different plant and soil nematodes and on integrated pest management. It remains an invaluable resource for those studying and working in the area of crop protection.
