Book Description
The need to identify and name organisms is fundamental to any area of biological science, basic or applied. In order to study or conduct research on an organism, or to convey information on this organism to others, we must be able to attribute to it a consistent label. Attribution of an incorrect label may have dire consequences if dangerous plant parasites are wrongly identified as members of an innocuous genus. Traditional aids to nematode identification (dichotomous keys) use systematic criteria not always well adapted to practical identification. Their reliance on dichotomous principlesdoes not allow for intra-taxon variability or for missing characters. They are difficult to update and they cannot keep pace with rapidly changing classifications. As experts in everyday life, we recognize a horse or a dog wi thout referring to the taxonomic descriptions of the genera Equus or Canis and their respective species. Problems in identification arise when we are not experts in the recognition of a particular organism, or group of organisms. Then, frequently in considerable frustration, we reflect on the usefulness of having the advice of an expert in this group. Tradi tional identification aids are useful tools for the expert identifiers, and for teaching. Their use is often difficult for general practitioners in nematology, and they may lead to incorrect identification, even at the genus level.

Book Description
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.

Book Description
Root-knot nematodes are the most economically important group of plant-parasitic nematodes worldwide, and their control presents a major global challenge. Advances are being made in understanding their biology, host-parasite interaction and management strategies. Covers the taxonomy, classification, morphology, life-cycle biology, genomes, resistance, sampling, detection, and management strategies of these pests.

Book Description
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.

Book Description
This book gives a comprehensive account of all aspects of plant nematology and should be of profound help to the students, teachers, researchers and extension workers alike. The syllabus of ARS Net – Nematology has also been fully covered in this book. Hence, persons appearing for ARS Net – Nematology can also refer this book. The book is divided into eight sections. The first section describes the importance of nematodes in agriculture, presents a historical review, nematode as biological models, entomopathogenic nematodes, and lists the professional societies and their publications.Information on the nematological techniques is outlined in section two.The morphology of nematodes is described and presented in clear schematic drawings in section three. The taxonomic classification along with keys for identification of nematodes up to generic level is provided. In section four, the biology, physiology and ecology of nematodes are described.The host-parasite interactions and symptoms on aerial and under-ground infestation by different nematodes are described and depicted in many photographs in section five. In section six, the interrelationships between nematodes and fungi, bacteria and viruses are discussed.Management of nematode diseases by host resistance and by suppression of nematode population through regulatory, physical, cultural, chemical, biological, and integrated methods have been presented in section seven.The last section of the book discusses the most important nematode induced diseases of horticultural, plantation and spices, commercial and field crops and their management. The selected references provide convenient entry to both current and older literature. Very useful information in the form of common names of nematodes and a glossary of nematological terms are provided in Annexures. This book will give students, teachers, researchers and extension workers with an overview of the entire field of Plant Nematology.

Book Description
Plant parasitic nematodes are a main pest to crops. For ex am pie, the root-knot nematodes belonging to the genus Meloidogyne are worldwide in their distribution and attack almost every type of crop, causing considerable losses of yield and affecting quality of produce. The cyst nematodes within the genera Globodera and Heterodera constitute a major group of plant pathogens in many countries throughout the world, suppressing yields of potato, sugar beet, soybean and cereals. Several nematodes such as longidorids and trichodorids are implicated in the transmission of numerous plant viruses. Many others cause constraints to agricultural production either locally or on large areas. However, despite their economic importance (they account for worldwide crop reduction in excess of 10%), plant parasitic nematodes are still poorly understood, because most of them are obligate parasites of roots. Environmental concerns over the agricultural use of pesticides demand the development of alternative measures to control them. To achieve environmentally sound control, knowledge of the basic biology of nematodes must be expanded. Important research areas include understanding the molecular bases for pathogenicity, the molecular mechanisms of the host parasite interactions and the genetic bases for population fluctuations. The workshop has, for the first time, brought together an international group of researchers using molecular approaches to study plant parasitic nematodes and their host responses.
