In 24 chapters, the authors have presented a clear, concise account of our present knowledge of the more important plant parasitic and pathogenic nematodes. Their teaching experience is evident not only in the arrangement of the text but in the examples presented and the methods of presentation. In addition to being an excellent text for an introductory course in nematology, it is also an easily read, authoritative account that will be of interest to all who are concerned with plants and how they grow.
