The book has been designed in such a way that students can able to understand the basic concepts of Nematology. The book includes the chapters: Introduction, History of Plant Nematology, Morphology of Plant Parasitic Nematodes, Taxonomy of Plant Parasitic Nematodes, Nematological Techniques, Nematode Control in Crop Plants, Host Parasite Relationship and Disease Development, Plant Disease Caused by Nematodes, Principles of Nematode Management, Equipment and Materials for the Laboratory, Some Economically Important Plant-Parasitic Nematodes of Selected Crops. 

The book will serve as a basic resource for the undergraduate and post graduate students of Nematology. It will also be useful for plant pathologists, botanists, zoologists and agricultural scientists.
