The second edition of this widely used manual has been revised and updated. Some drawings and illustrations have been replaced and new ones added. Suggestions have been made to divide the manual into two separate editions-one, on the study of insects and related forms; the other on the study of plant diseases. However, many of the studies involve both these fields of plant protection. The authors believe that in an applied introductory course their integration gives the students a much broader basis of understanding the problems involved in diagnosing and controlling plant health problems. We therefore, have decided to retain the integrated format.

Identification schemes; Gram-negative bacteria; Gram-positive bacteria; Cell wall-free prokaryotes.

The first edition of Potato Health Management is the best-selling title in the APS PRESS Plant Health Management Series, with more than 7,000 copies sold. Pest and pathogen populations have changed since the first edition was printed and a significant amount of new research knowledge has been gained. This second edition addresses those changes and contains up-to-date information recently acquired to help you economically manage potato health. This highly-anticipated manual tackles the hundreds of problems that affect this important crop including weeds, insects, nematodes, fungi, bacteria, phytoplasmas, and viruses. The new edition is 30% larger than the first and contains more color photographs, which are now interspersed throughout the text. It includes timely new chapters on economics, home gardening, and organic production. More than 40 experts from the fields of soil science, weed science, nematology, plant pathology, and entomology explain how to manage potato health from seed to storage by a holistic approach. The book provides the most current information on potato production practices, with an emphasis on pest and disease management. The knowledge base provided in this text can be integrated into a comprehensive management scheme in the context of today's agriculture. Using this manual's integrated strategy for potato health management will help you produce a quality product at a reasonable profit, using an environmentally friendly approach. Potato Health Management, Second Edition is easy to read and understand. Call-outs of important concepts give quick information to supplement the more-in-depth level of peer-reviewed information. Nearly every chapter includes a boxed briefing on an important concept, helpful test, diagnostic tip, or checklist, adding to your practical understanding of potato health management strategies. The information in each of the book's 23 chapters is essential to a successful, holistically managed potato health management program. Cutting edge discussions and details on soil health, managing tubers during harvest and in storage, organic potato production, pesticide resistance management, pesticide application, management of diseases, insects and weeds affecting potato will enlighten commercial potato growers, field consultants and farm advisors, extension specialists, agriculture students, researchers and agribusiness professionals in all aspects of the potato industry. The 42 contributing experts are from the leading potato research facilities in the United States and Canada, but the information in the handbook will provide valuable practical assistance to potato professionals outside of North America as well. - Publisher.

Insects and non-insect pests are responsible for causing extensive damage to crops in the field and to grains and stored products in the warehouses and godowns, which necessitates their control. In this book, the author has given:- Detailed account of major insect and non-insect pests of economically important field and horticultural crops and possible measures of their control. Information about household pests, which damage human possessions, as well as insect and non-insect pests, which either cause diseases or transmit various diseases in plants, livestock and humans. A list of minor pests of each crop, which may attain the level of major pests when conditions become favorable for them. List of insecticides approved by the Government of India for use as spray chemicals and granular insecticides and the dosage for their use. The text is substantiated with many, fine hand-drawn illustrations, depicting the nature of damage and life cycle of the pests, which is the highlight of this book. The book is intended primarily for the Under Graduate students of Agriculture, but it will be immense use for the Post Graduate students of Agriculture, officials working in the Department of Agriculture, those interested in scientific farming and for the general public.

For the first time in over 20 years, a comprehensive collection of photographs and descriptions of species in the fungal genus Fusarium is available. This laboratory manual provides an overview of the biology of Fusarium and the techniques involved in the isolation, identification and characterization of individual species and the populations in which they occur. It is the first time that genetic, morphological and molecular approaches have been incorporated into a volume devoted to Fusarium identification. The authors include descriptions of species, both new and old, and provide protocols for genetic, morphological and molecular identification techniques. The Fusarium Laboratory Manual also includes some of the evolutionary biology and population genetics thinking that has begun to inform the understanding of agriculturally important fungal pathogens. In addition to practical “how-to” protocols it also provides guidance in formulating questions and obtaining answers about this very important group of fungi. The need for as many different techniques as possible to be used in the identification and characterization process has never been greater. These approaches have applications to fungi other than those in the genus Fusarium. This volume presents an introduction to the genus Fusarium, the toxins these fungi produce and the diseases they can cause. "The Fusarium Laboratory Manual is a milestone in the study of the genus Fusarium and will help bridge the gap between morphological and phylogenetic taxonomy. It will be used by everybody dealing with Fusarium in the Third Millenium." --W.F.O. Marasas, Medical Research Council, South Africa
