In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of m.

Every year we see a remarkable increase in scientific knowledge. We are learning more each day about the world around us, about the numerous biological organisms of the biosphere, about the physical and chemical processes that shaped and continue to change our planet. The cataloging, retrieval, dissemination, and use of this new information along with the continued development of new computer technology provide some of the most challenging problems in science as we enter the Information Age. With the explosion of knowledge in science, it is especially important that students in introductory courses learn not only the basic material of a subject, but also about the newest developments in that subject. With this goal in mind, we have prepared a second edition of Introduction to Plant Diseases: Identification and Management. We prepared this edition with the same general purpose that we had for the first edition - to provide practical, up-to-date information that helps in the successful management of diseases on food, fiber, and landscape plants for students who do not have a strong background in the biological sciences. We included new information on (1) the precise identification of diseases and the pathogens that cause them, (2) the development of epidemics of plant diseases, (3) the application of biotechnology in plant pathology, (4) the use of alternative methods of crop production and disease management that help protect the environment, and (5) diseases that have become more important since the first edition was published.

Plants, fungi, and viruses were among the first biological objects studied with an electron microscope. One of the two first instruments built by Siemens was used by Helmut Ruska, a brother of Ernst Ruska, the pioneer in constructing electron microscopes. H. Ruska published numerous papers on different biological objects in 1939. In one of these, the pictures by G. A. Kausche, E. Pfankuch, and H. Ruska of tobacco mosaic virus opened a new age in microscopy. The main problem was then as it still is today, to obtain an appropriate preparation of the specimen for observation in the electron microscope. Beam damage and specimen thickness were the first obstacles to be met. L. Marton in Brussels not only built his own instrument, but also made considerable progress in specimen preparation by introducing the impregnation of samples with heavy metals to obtain useful contrast. His pictures of the bird nest orchid root impregnated with osmium were revolutionary when published in 1934. It is not the place here to recall the different techniques which were developed in the subsequent years to attain the modern knowledge on the fine structure of plant cells and of different plant pathogens. The tremendous progress obtained with tobacco mosaic virus is reflected in the chapter by M. Wurtz on the fine structure of viruses in this Volume. New cytochemical and immunological techniques considerably surpass the morphological information obtained from the pathogens, especially at the host-parasite interface.

Plant diseases play an important role on our daily lives. Most of plant diseases are visible and are caused by biotic and/or abiotic factors. Symptoms are usually the results of a morphological change, alteration or damage to plant tissue and/or cells due to an interference of the plant’s metabolism. All basic structures of vascular plants are subject to attack by pathogens. The failure in accurate disease diagnosis and management may lead to huge losses in plant production and related commodities, which causes nutritional food scarcity. Typically, the appearance of a biotic symptom will indicate the relatively late stage of an infection and/or colonization of a pathogen. Expert detection, accurate diagnosis, and timely management play a significant role in keeping plants free from pathogens. In this book expert scholars share their research knowledge and key literature which are vital toward the diagnosis of plant diseases across the globe, addressing traditional plant pathology techniques, as well as advanced molecular diagnostic approach.

The past decade is probably unparalleled as a period of dynamic changes in the crop protection sciences-entomology, plant pathology, and weed science. These changes have been stimulated by the broad-based concern for a quality environment, by the hazard of intensified pest damage to our food and fiber production systems, by the inadequacies and spiraling costs of conventional crop protection programs, by the toxicological hazards of unwise pesticide usage, and by the negative interactions of independent and often narrowly based crop protection practices. During this period, the return to ecological approaches in crop protection was widely accepted, first within entomology and ultimately within the other crop protection and related disciplines. Integrated pest management is fast becoming accepted as the rubric describing a crop pro tection system that integrates methodologies across all crop protection dis ciplines in a fashion that is compatible with the crop production system. Much has been written and spoken about "integrated control" and "pest management," but to date no treatise has been devoted to the concept of "in tegrated pest management" in the broadened context as described above. Most of the manuscripts in this volume were developed from papers presented in a symposium at the annual meeting of the American Association for the Ad vancement of Science held in San Francisco in February, 1974. In arranging that symposium, the editors involved plant pathologists, entomologists, and weed scientists.

This book brings together twelve chapters on fungal pathogens with the goal of presenting an overview of the current areas of activity and the common themes that pervade research on these important organisms. The timing of the book is appropriate because we have gained sufficient insight from molecular genetic analyses to begin to make some comparisons between different fungal pathogens and to discuss the key advances that have been made. The chapters provide a broad survey of the important topics in fungal pathogenesis including morphogenesis, virulence, avirulence, and signaling. The reader also will fmd clear discussions of parasitism, mutualism, symbiosis, evolution, phylogeny and ecology for those fungi where these issues are especially important. Finally, many of the chapters in this book illustrate the fact that we are on the verge of a revolution in our understanding of fungal pathogens because of the application of genomics to these organisms and their hosts. The fungi included in this book represent many of the most intensively investigated fungal pathogens of plants; in this regard, a chapter is also included for pathogens in the Phytophthora group, even though these organisms are no longer classified as fungi. It is appropriate to include Phytophthora for historical reasons and, in addition, the insights in terms of pathogenesis and host-specific interactions are important to keep in mind when considering fungal pathogens. Chapters are also included on pathogens of insects and humans, as well as endophytic fungi.

Sustainable Management of Arthropod Pests of Tomato provides insight into the proper and appropriate application of pesticides and the integration of alternative pest management methods. The basis of good crop management decisions is a better understanding of the crop ecosystem, including the pests, their natural enemies, and the crop itself. This book provides a global overview of the biology and management of key arthropod pests of tomatoes, including arthropod-vectored diseases. It includes information that places tomatoes in terms of global food production and food security, with each pest chapter including the predators and parasitoids that have specifically been found to have the greatest impact on reducing that particular pest. In-depth coverage of the development of resistance in tomato plants and the biotic and abiotic elicitors of resistance and detailed information about the sustainable management of tomato pests is also presented. Provides basic biological and management information for arthropod pests of tomato from a global perspective, encompassing all production types (field, protected, organic) Includes chapters on integrated management of tomato pests and specific aspects of tomato pest management, including within protected structures and in organic production Presents management systems that have been tested in the real-world by the authors of each chapter Fully illustrated throughout with line drawings and color plates that illustrate key pest and beneficial arthropods associated with tomato production around the world

For the past decade, it has been apparent to both of us that a reference text covering all aspects of tree defense mechanisms to fungi was missing, needed and long overdue. Such a book would provide a clear, comprehensive overview of how living roots, stems and leaves respond to fungal pathogens. The need for such a book became in creasingly clear to us from our conversations with each other, as well as from our interactions with students and colleagues who desired a sourcebook containing reviews of morphological, biochemical and physiological aspects of host-parasite interactions in trees. During a field trip sponsored by the Forest Pathology Committee of the Ameri can Phytopathological Society, on a bus from one site to another, we decided to take the responsibility to prepare a book of this type and began to plan its composition. To adequately address the topic of this book as we had envisioned it, we believed that well-illustrated chapters were needed in order to reflect the important advances made by the many investigators who have examined the anatomical and physiological changes that occur when trees are attacked by fungi. We are grateful to Dr. Tore Timell, the Wood Science editor for Springer-Verlag, for supporting our efforts and for providing an avenue to publish such a profusely il lustrated volume.

Given the central role of the food and agriculture system in driving so many of the connected ecological, social and economic threats and challenges we currently face, Rethinking Food and Agriculture reviews, reassesses and reimagines the current food and agriculture system and the narrow paradigm in which it operates. Rethinking Food and Agriculture explores and uncovers some of the key historical, ethical, economic, social, cultural, political, and structural drivers and root causes of unsustainability, degradation of the agricultural environment, destruction of nature, short-comings in science and knowledge systems, inequality, hunger and food insecurity, and disharmony. It reviews efforts towards ‘sustainable development’, and reassesses whether these efforts have been implemented with adequate responsibility, acceptable societal and environmental costs and optimal engagement to secure sustainability, equity and justice. The book highlights the many ways that farmers and their communities, civil society groups, social movements, development experts, scientists and others have been raising awareness of these issues, implementing solutions and forging ‘new ways forward’, for example towards paradigms of agriculture, natural resource management and human nutrition which are more sustainable and just. Rethinking Food and Agriculture proposes ways to move beyond the current limited view of agro-ecological sustainability towards overall sustainability of the food and agriculture system based on the principle of ‘inclusive responsibility’. Inclusive responsibility encourages ecosystem sustainability based on agro-ecological and planetary limits to sustainable resource use for production and livelihoods. Inclusive responsibility also places importance on quality of life, pluralism, equity and justice for all and emphasises the health, well-being, sovereignty, dignity and rights of producers, consumers and other stakeholders, as well as of nonhuman animals and the natural world. Explores some of the key drivers and root causes of unsustainability , degradation of the agricultural environment and destruction of nature Highlights the many ways that different stakeholders have been forging 'new ways forward' towards alternative paradigms of agriculture, human nutrition and political economy, which are more sustainable and just Proposes ways to move beyong the current unsustainable exploitation of natural resources towards agroecological sustainability and overall sustainability of the food and agriculture system based on 'inclusive responsibility'
