Available in PDF, EPUB and Kindle. Book excerpt: Because of the recently increased use of legumes as substitutes for nitrogenous fertilizers to conserve nitrogen for our war efforts, it is important that all usable information on the diseases of these crops be made available to pathologists at once so that their efforts to control these diseases may be speeded. This need for assembled information has prompted the preparation of this material for publication at this time.

Book excerpt: This book is a guide to the fungi of Kansas. It will familiarize you with some of the most common and some of the most beautiful of the state's fungal flora. But it is designed to do much more. It will introduce you to a variety of ways to enjoy mushrooms. For most people they are things of beauty and wonder, to be discovered unexpectedly on a walk in the woods; some try to preserve and communicate their sense of awe on film; others only want to find delectable morsels for the table; a few strive to find rarities or to identify mysterious strangers. This book will help you take the first steps in all these approaches to the world of mushrooming.

This book was released on 2013-06-29 with total page 1031 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was a compliment to me to be asked to prepare the fourth edition of Westcott's Plant Disease Handbook, and the decision to accept the respon sibility for the fourth edition, the fifth edition, and now the sixth edition was not taken lightly. The task has been a formidable one. I have always had great respect professionally for Dr. Cynthia Westcott. That respect has grown considerably with the completion of the three editions. I now fully realize the tremendous amount of effort expended by Dr. Westcott in de veloping the Handbook. A book such as this is never finished, since one is never sure that everything has been included that should be. I would quote and endorse the words of Dr. Westcott in her preface to the first edition: "It is easy enough to start a book on plant disease. It is impossible to finish it. . . " This revision of the Handbook retains the same general format contained in the previous editions. The chemieals and pesticides regulations have been updated; major taxonomie changes have been made in the bacteria, fungi, nematodes and viruses; the changing pieture in diseases caused by viruses and/ or viruslike agents have been described. New host plants have been added, and many recently reported diseases as weIl as previously known diseases listed now on new hosts have been included.
Download or read book The Cereal Rusts written by William Bushnell and published by Elsevier. This book was released on 2012-12-02 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cereal Rusts, Volume I: Origins, Specificity, Structure, and Physiology presents the historical, evolutionary, taxonomic, structural, genetic, and physiological characteristics of cereal rust fungi and the diseases they cause in cereal crops. The cereal rusts are potentially serious disease threats to cereal crops and have caused widespread losses in wheat, oats, barley, and related crops. This three-part volume brings together in a single reference source the accumulated knowledge, complex, challenging science of cereal rusts. The first chapters of this 16-chapter volume cover the pioneering contributions of early scientists to the knowledge of cereal rusts, the evolution of cereal rusts, and the taxonomy of cereal rust fungi. The book also examines the specificity of cereal rusts including formae speciales, race specificity, pathogen-host genetics, histology and molecular biology of host parasite specificity, and the genetics of rust fungus populations as reflected by virulence frequency. The text further discusses the structure and physiology aspects; the germination of urediospores and differentiation of infection structures; and the infection under artificial conditions. The ultrastructure of hyphae and urediospores; the development and physiology of teliospores; and the obligate parasitism and axenic culture of rust fungi are also explained. This volume also encompasses the structure and physiology of haustoria; structural and physiological alterations in susceptible hosts; and effects of rust on plant development in relation to nutrient translocation. Cereal rust investigators, plant pathologists, agronomists, agriculturalists, research biochemists, cytologists, geneticists, physiologists, taxonomists, epidemiologists, and pathologists will find this book invaluable.

Download or read book The Handbook of Mites of Economic Plants written by Vincenzo Vacante and published by CABI. This book was released on 2015-12-21 with total page 892 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mites pose a serious problem to plants worldwide, attacking crops and spreading disease. When mites damage crops of economic importance the impacts can be felt globally. Mites are among the most diverse and successful of invertebrates, with over 45,000 described species, with many more thousands to be discovered. They are responsible for a significant portion of the losses of crops for food, fibre, industry and other purposes, and require expensive and often controversial pest control measures. Understanding these mites is vital for entomologists, pest researchers, agronomists and food producers. Knowledge of mite pests helps to inform control strategies and optimize the production of economic plants and the agrarian economy. This encyclopedia provides a thorough coverage of the mites and the problems they cause to crops, yet it is easily searchable, organised by mite species and subdivided into helpful headings. It takes a worldwide view of the issue of mites injurious to economic plants, describing mites prevalent in different regions and discussing control methods appropriate in different environments. This book provides an encyclopaedic reference to the major mites, described by family in terms of their internal and external morphology, bio-ecology and family systematics. Methods of mite collection and laboratory study is described, as well as species diagnostic characteristics, worldwide distribution, host plants, identification by the type of damage they cause and control strategies, including chemical and biological intervention and integrated pest management measures. Mites of the following families are included: (Eriophyoidea, Tarsonemidae, Tuckerellidae, Tenuipalpidae, Tetranychidae, Acaridae, Penthaleidae). Mites of Economic Plants is an important resource for students of entomology and crop production, and as a thorough reference guide for researchers and field workers involved with mites, crop damage and food production.
