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.

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.

The book is written for under-graduate students of agriculture, horticulture and post graduates specializing in Nematology and Entomology dealing with plant parasitic nematodes. This book covers historical background including the developments in India and abroad, details of morphology, anatomy and taxonomy of plant parasitic nematodes, relevant nematological techniques and focus on nematode problems in important crop plants and their management.

The Dorylaimida represent a large and very important group of soil and freshwater inhabiting nematodes of great agricultural importance. Both in appearance and mode of life they represent a wide diversity and as a consequence the number of species and higher taxa that have been described hitherto is the highest within Nematoda. The identification of species, genera, families, etc. of Dorylaimida is very difficult and at times causes problems for the specialist too. The large number of species on the one hand and often the meagre descriptions on the other make even well-known taxonomists to look at Dorylaimida with great hesitation and desperation. M. Shamim Jairajpuri and Wasim Ahmad have undertaken a great task in summarizing, evaluating and systematizing all the knowledge that has been published so far.
