Nematology is the discipline of science that deals with the study of nematodes or roundworms. Current requirements of practical nematological work and unavailability of expertise and studies in this field indicate a dire need to encourage the likes of this book on the neglected groups of organisms. The authors, in the present book, have attempted to cover the practical aspects of Nematology for U.G. and P.G. students, teachers and research workers. Rather than enlisting numerous methods adopted by various workers, an emphasis is given to most commonly used techniques for every exercise. Additionally, to gain in depth knowledge on a particular topic, further readings have been suggested at the end of each exercise. Illustrations have also been given that will help the readers in the identification of common nematode species and disease symptoms caused by them.

This book is the first complete illustrated compendium of root-knot nematode species from the genus Meloidogyne including 97 species descriptions with comprehensive diagnoses, information on biology, plant-hosts, pathogenicity, symptoms, distribution and biochemical and molecular diagnostics.
Nematodes are one of the most abundant groups of invertebrates on the face of the earth. Their numbers are estimated to range from 1000 per cm2 in the sand-covered hydrogen sulphide ‘black zone’ beneath the ocean floors to 1.2 billion in a single hectare of soil. Estimates for their species diversity range from 100 000 to 10 million. The past history of nematodes is a mystery, since very few fossils have been discovered. This book establishes a solid base in palaeonematology with descriptions of 66 new fossil species and accounts of all previous fossil and subfossil nematodes from sedimentary deposits, coprolites, amber and mummies. It shows how nematode fossils can be used to establish lineages at various locations and time periods in the earth’s history and when nematodes entered into symbiotic and parasitic associations with plants and animals.
This volume gives a detailed morphology of the dorylaims and provides a thorough overview of their feeding behaviour, reproduction, ecology, and diversity. You will learn what dorylaims are like and how they live.

This unique book contains not only a comprehensive up-to-date summary of the achievements made in all areas of Nematology in South Africa over more than half a century, but it also combines this rather technical part with an insiders narrative of how Nematology started and developed. It also demonstrates how the South African community of nematologists gradually adapted to major changes in agriculture. These were due to a major political shift followed by socio-economic changes and this in an often challenging natural environment. At the same time this book is conceived as a useful source for young scientists to provide them with practical knowledge and critical insight in the field of Nematology. The information given is based primarily on research conducted by nematologists in South Africa. Most of this research was aimed at finding workable solutions for nematological problems confronted by both large-scale commercial producers and smallholding farmers. During a period when funding for scientific research is becoming increasingly scarce, the future demand and quest for practical solutions by applied research will only increase.
Vegetable Diseases focuses primarily on diseases that are caused by pathogens. Chapters dealing with the general principles of the causes, diagnosis and control of vegetable crop diseases are followed by crop-based chapters. Each disease entry includes a brief introduction to the disease, detailed description of disease symptoms, information on the pathogen and disease development, and suggestions on how to manage the problem. Top quality color photos illustrate the book throughout.
