In the context of increasing international concern for food and environmental quality, use of Plant Growth-Promoting Rhizobacteria (PGPR) for reducing chemical inputs in agriculture is a potentially important issue. PGPR are root-colonizing bacteria that exert beneficial effects on plant growth and development, but they can be also employed in the control of plant pathogens, for enhancing the efficiency of fertilizers, and for degrading xenobiotic compounds. This book provides an update by renowned international experts on the most recent advances in the ecology of these important bacteria, the application of innovative methodologies for their study, their interaction with the host plant, and their potential application in agriculture.

Plant diseases and changes in existing pathogens remain a constant threat to our forests, food, and fiber crops as well as landscape plants. However, many economically important pathosystems are largely unexplored and biologically relevant life stages of familiar systems remain poorly understood. In a multifaceted approach to plant pathogenic behavioral control, Sustainable Approaches to Controlling Plant Pathogenic Bacteria discusses the impact of plant pathogenic bacterial pathogenesis on scientific and economic levels. It introduces mechanisms, measuring tools, and controlling strategies you can use to meet the challenge of developing new and innovative ways to control plant diseases. The book covers many aspects of the activities of pathogenic bacteria that interact with plants. With chapters contributed by experts, the book focuses on: Pathogenesis Epidemiology Forecasting systems Control measures including diagnosis, quarantine, and eradication Adoption of agro-traditional practices Tools for the control of antibacterial polypeptides Nutrient supplements Metabolic substances from other organisms Mechanisms of siderophores Host resistances Quorum sensing and quenching Seed and foliar applications Impact of plant pathogens on scientific and economic levels The editors' approach provides a broad perspective, including modern trends in ecology that consider plant pathogenic bacterial control from all angles. The discussions and reviews in the book cover a wide range of aspects of plant pathogenic bacterial pathogenicity, epidemiology, and impact on the food chain as well as strategies for control, which will help you develop sustainable methods for controlling plant diseases.

Plant disease epidemiology is a dynamic science that forms an essential part of the study of plant pathology. This book brings together a team of 35 international experts. Each chapter deals with an essential component of the subject and allows the reader to fully understand how each exerts its influence on the progress of pathogen populations in plant populations over a defined time scale. This edition has new, revised and updated chapters.

Handbook of Plant Disease Identification and Management presents the fundamentals of plant diseases identification based on symptomology and management focusing mainly on integrated pest management approach. It discusses a variety of techniques for the diagnosis of crop disease, losses due to crop diseases, and theories behind disease management. It describes how society is constraining the possibilities for management of crop diseases by changing the environment; biologically controlling crop diseases; and the epidemiologic and genetic concepts of managing host genes. This book discusses managing diseases through diverse chemical, biological, and physical methods. It highlights climatic factors affecting crops by creating favorable condition for most of the diseases. This book serves as a complete guide for growers, researchers, and graduate students to understand basics of plant disease identification. It explains the disease cycle for respective crops with favorable conditions promoting disease development. It intends to aid growers in managing diseases and help scientists with future research.

Since the identification of insect pheromones in the late 1950s, attention has often focused on the use of these potent behavior-modifying chemicals as pest control agents. Much of this interest has concentrated on Lepidoptera, particularly moths. In addressing this topic in other insect orders, this multi-author book fills this current gap in the literature. It presents research from leading authorities on the most important insect groups, and details the current progress of research in these areas. Applications of the research to agricultural systems around the world, and possible mechanisms for sustainable crop protection, are considered. This book is essential reading for students and researchers in entomology and crop protection.

The Advanced Text series is designed for students taking advanced-level courses, including final year undergraduates and taught MSc. Titles in this series will also be invaluable to researchers new to the field, and to established researchers as a basic reference text. Studies of the interactions between plants and their viral, bacterial and fungal pathogens are of major importance in plant and crop production. More than 10 per cent of potential agricultural yield is lost to these organisms annually worldwide, and major epidemics can cause significant local economic and environmental damage. Molecular Plant Pathology addresses the underlying molecular principles of plant/pathogen interactions, in a readily-accessible textbook format.

Healthy seeds and propagules are the basic requirement for producing good grains, fruits and vegetables needed for human survival and perpetuation. Dispersal of microbial plant pathogens via seeds and propagules has assumed more importance than other modes of dispersal, as infected seeds and propagules have the potential to become the primary sources of carrying pathogen inoculum for subsequent crops. Several diseases transmitted through seeds and propagules have been shown to have the potential to damage economies as a result of huge quantitative and qualitative losses in numerous crops. Hence, it is essential to rapidly detect, identify and differentiate the microbial plant pathogens present in seeds and propagules precisely and reliably, using sensitive techniques. Microbial Plant Pathogens: Detection and Management in Seeds and Propagules provides a comprehensive resource on seed-borne and propagule-borne pathogens. Information on the biology of microbial pathogens, including genetic diversity, infection process and survival mechanisms of pathogens and epidemiology of diseases caused by them, are discussed critically and in detail to highlight weak links in the life cycles of the pathogens. Development of effective disease management systems, based on the principles of exclusion and eradication of pathogens and immunization of crop plants to enhance the levels of resistance of cultivars to diseases, has been effective to keep the pathogens at bay. The need for production of disease-free seeds/propagules has been emphasized to prevent the carryover of the inoculum to the next crop or introduction of the pathogens to other locations. Effectiveness of adopting simple cultural practices and development of cultivars resistant to diseases through traditional breeding methods or biotechnological approach have resulted in reducing the pathogen inoculum and disease incidence. Although application of different chemicals may reduce the disease incidence effectively, biological management of crop diseases, employing potential biological control agents have to be preferred to preserve the agroecosystems. Greater efforts have to be made to integrate compatible strategies to enhance the effectiveness of diseases management systems. Protocols appended at the end of relevant chapters form a unique feature of this book to enable the researchers to fine-tune their projects. This 2 volume set provides comprehensive and updated information about the economically-important groups of microbial plant pathogens carried by seed and propagules. Graduate students, researchers and teachers of plant pathology, plant protection, microbiology, plant breeding and genetics, agriculture and horticulture, as well as certification and quarantine personnel will find the information presented in this book useful.

This book provides practical, up-to-date information that helps in the successful management of diseases on food, fibre and landscape plants for students who do not have a strong background in the biological sciences. It is largely revised to reflect the recent problems in conventional agriculture with an environmental emphasis and to include the latest techniques in biotechnology and genetic engineering. This edition includes information on the more precise indentification of diseases and the pathogens that cause them, the development of epidermics of plant diseases, the application of biotechnology in plant pathology and the use of alternative methods of crop production and disease management. This book should be of interest to agricultural consultants; chemical company representatives; sales personnel; courses in biological sciences and agriculture in high schools; technical colleges.

This comprehensive dictionary provides an essential reference for plant pathologists and agriculturalists at all levels, listing the authoritative names of all major plant pathogens. The 11,000 entries, which include fungi from over 500 genera, 800 viruses, bacteria, mollicutes, nematodes and viriods, contain brief descriptions and thorough supporting references. There are also entries for the names of diseases and disorders, crops and their pathology, fungicides, taxonomic groups, terminology, toxins, vectors and past plant pathologists. Overall, the volume provides a wide-ranging resource for all those working in the discipline. In this new edition over 3000 entries have been added and many existing entries updated and expanded. In addition, common disease names such as "blight" and "canker" are now more conveniently included under the relevant crop.

This book is about how plants get diseases, from the origins and evolution of parasites to how the great plant epidemics developed. The basic premise of the book is that the conditions favouring disease are inherent in agriculture and that diseases become destructive because of human activities. It also deals with how people have dealt with plant diseases in history. Included in the book are the natural histories of some of the most damaging plant diseases, worldwide, with discussions of why each became destructive. Diseases are grouped according to the most significant factors in the development of epidemics: in every case this is due to a human factor. Discussion of each model disease proceeds from observable facts to more complex concepts; thus, the reader with little knowledge of plant pathology should find the book easily understandable.

Over the course of evolution, fungi have adapted to occupy specific niches, from symbiotically inhabiting the flora of the intestinal tract of mammals to saprophytic growth on leaf litter resting on the forest floor. In Plant Fungal Pathogens: Methods and Protocols, expert researchers in the field detail many of the methods which are now commonly used to study fungal plant pathogens. These include methods and techniques for model systems such as Arabidopsis thaliana as well as crop plants, aspects of fungal biology, genome annotation, next-generation sequencing, and fungal transformation and molecular tools for disease and/or pathogen quantification that are critical for revealing the role for a fungal gene of interest in disease development. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Plant Fungal Pathogens: Methods and Protocols seeks to aid scientists in the further study in current techniques that cover a wide-range of methods to study molecular aspects of pathogenesis.

Protocols in Molecular Parasitology offers a wide range of experi mental protocols, each written by experts, to research workers interested in exploring the molecular aspects of parasitology. This is a field that has expanded enormously in scope and potential over the last decade, although it is as yet significantly underrepresented in the literature out side of academic journals. The need for manuals such as this one stems in part from the increasing difficulty of reproducing experimental tech niques from reports in standard journal papers, where pressures on space usually result in highly abbreviated descriptions. The "Notes" sections of the following chapters are particularly aimed at counteracting this problem. Since the emphasis of the book is on aspects of molecular analysis, it was possible to devote only a limited amount of space to describing protocols for culture and isolation of the primary parasitic material. Therefore, of the numerous parasitic systems that are currently being investigated in laboratories around the world, only techniques for c- turing the "big five" are described here, since they collectively account for the great bulk of research in this field. It is also possible that some minor front-end modifications to certain protocols may be necessary, depending on exactly which parasite is being studied."

A number of economically important diseases are caused by potyviruses, the largest group of plant viruses. Many of these diseases are distributed worldwide. The development of effective control strategies against viruses is dependent on the availability of reliable methods of identification and detection. To date this has not seemed possible for the potyvirus group, because of its size, complexity, and immense variation. This book brings together the collaborative efforts of exports in the field. It summarizes characteristics of potyviruses which relate to their taxonomy and points to areas which require consideration before an international consensus can be reached. Main topics dealt with in detail are: serological relationships, nucleic acid sequence information, biological properties, and specific problems with several virus subgroups or pairs of viruses.

The increasing use of integrated crop management, often requiring a reduction in the reliance upon chemical control, means that the need to rapidly identify pest nematodes has never been greater. This second edition of this standard reference work familiar to all plant nematologists is therefore even more useful than its predecessor published in 1986. The in-depth description of the life histories of the genera of the Tylenchida have been retained and brought up-to-date through the inclusion of all the research carried out between the publication of the last edition and this new edition. This expanded edition includes detailed diagnoses of well over 200 genera and familial and ordinal groups and the book is heavily illustrated with drawings of type or representative species. These, together with comprehensive lists of species and genera and their synonymies provide the foundation for the status and validation of each taxon within the Tylenchida. A considerable amount of information is provided regarding the biology, ecology and pathogenicity of these parasites. This book is the only comprehensive reference work on this important group of nematodes.

There is a growing awareness that an understanding of international plant health agreements and protocol is essential in the increasingly free-trade environment of today, and that administrative methods of plant pest control are important in crop production. However, there has been no recent book, which introduces students and practitioners to the subject of plant health and quarantine. This book fills this gap.

There is increasing interest in the use of fungi for the control of pests, weeds and diseases. This book brings together perspectives from pathology, ecology, genetics, physiology, production technology, to address the use of fungi as biological control agents.

Palms constitute one of the largest botanical families, and include some of the world s most important economic plants. They are also unequalled as outdoor and indoor ornamental plants, and include many species that are essential components of the ecosystems of tropical and other warm regions. This book reviews the inter-relationships between palms and insects, emphasizing the similarities in different world regions. The host plants, distribution, and bionomics of representative insects are discussed according to their feeding sites on palms (foliage, flowers, fruits, and stems) and their taxonomic groups. Host and distribution records for the most extensively represented insect families on palms are tabulated. Pest management and field techniques are also covered. This book is recommended reading for tropical biologists and agriculturalists, including entomologists, horticulturists and tropical ecologists as well as palm nursery growers, managers and enthusiasts."

Based on a similarly named meeting in December 1999, organized by the British Society for Plant Pathology, this book considers the biology of interactions between host plants and the pathogens that infect them. This important topic has seen some significant advances in the past 10 years, especially through the application of molecular techniques, which are extensively covered in this book.

Diseases caused by Ganoderma species cause major losses of palms and other perennial crops throughout the world, and these are particularly significant in Asia. Successive replanting of crop monocultures can be rapidly exploited by soil-borne fungi such as Ganoderma, and the problem will become more serious in the 21st century, as more areas become due for second or even third replanting. Environmental considerations will reduce exploitation of new forest areas, making further replanting of these crops inevitable. Thus, appropriate, integrated management systems for these diseases are vital. However, the development of such control measures has been hampered in the past by a limited knowledge of the nature and inter-relationships of populations of different hosts and the mechanisms of disease establishment and spread.This book aims to address these limitations through enhanced knowledge of the biology and taxonomy of Ganoderma species. The use of molecular and biochemical methods can be used to provide a greater understanding of the spread of the pathogen, and consequently, the improved management of disease.

Accurate and detailed information on the fundamental biology of free-living and plant-parasitic nematodes has several important functions. It is needed to gain an understanding of their highly complex ecology and, since many plant-parasitic nematodes are major agricultural pests, it also greatly enhances attempts to implement crop protection strategies. In addition, information on physiology and biochemistry has particular relevance to studies of gene function in nematodes and the nematode "Caenorhabditis elegans" has become established as one of the most important model organisms for molecular genetic studies. Written by leading research workers from Europe, USA, Australia and New Zealand, this is the only up-to-date reference book which reviews and integrates all the current research findings on the physiology and biochemistry of these organisms, including the molecular information which has accumulated in recent years. It is essential reading for researchers, advanced undergraduate and postgraduate students and lecturers in plant nematology, parasitology, plant pathology and agricultural zoology and will also be a valuable reference source for students of invertebrate biology, crop protection and pest management.

The population of the world continues to increase at an alarming rate. The trouble linked with overpopulation ranges from food and water scarcity to inadequacy of space for organisms. Overpopulation is also linked with several other demographic hazards, for instance, population blooming will not only result in exhaustion of natural repositories, but it will also induce intense pressure on the world economy. Today nanotechnology is often discussed as a key discipline of research but it has positive and negative aspects. Also, due to industrialization and ever-increasing population, nano-pollution has been an emerging topic among scientists for investigation and debate. Nanotechnology measures any substance on a macromolecular scale, molecular scale, and even atomic scale. More importantly, nanotechnology deals with the manipulation and control of any matter at the dimension of a single nanometer. Nanotechnology and nanoparticles (NPs) play important roles in sustainable development and environmental challenges as well. NPs possess both harmful and beneficial effects on the environment and its harboring components, such as microbes, plants, and humans. There are many beneficial impacts exerted by nanoparticles, however, including their role in the management of waste water and soil treatment, cosmetics, food packaging, agriculture, biomedicines, pharmaceuticals, renewable energies, and environmental remedies. Conversely, NPs also show some toxic effects on microbes, plants, as well as human beings. It has been reported that use of nanotechnological products leads to the more accumulation of NPs in soil and aquatic ecosystems, which may be detrimental for living organisms. Further, toxic effects of NPs on microbes, invertebrates, and aquatic organisms including algae, has been measured. Scientists have also reported on the negative impact of NPs on plants by discussing the delivery of NPs in plants. Additionally, scientists have also showed that NPs interact with plant cells, which results in alterations in growth, biological function, gene expression, and development. Thus, there has been much investigated and reported on NPs and plant interactions in the last decade. This book discusses the most recent work on NPs and plant interaction, which should be useful for scientists working in nanotechnology across a wide variety of disciplines.

In preparing the fifth edition of Plant Viruses the general plan of the book has been retained since this seems to offer adequate scope for a book of this size. However, each section has been brought up-to-date with any new information which has become available since the publication of the previous edition. Chapter 15 has been added giving a short account of two new fields of virus study, the viruses affecting fungi and algae. Some of the plates have been replaced by more modern illustrations. Reference to the aster yellows group of diseases has been eliminated because these diseases are now known to be caused by infection with Mycoplasma and not with viruses. Grateful acknowledgement is due to Dr Aaron Klug, F.R.S. and his colleagues for permission to use their recent work on the assembly of viruses. Acknowledgement is also due to several friends who have supplied prints of illustration from their pub lished work; credit has been given to authors in the illustration legends. Cambridge K.M.S.

The field of Phytobacteriology is rapidly advancing and changing, because of recent advances in genomics and molecular plant pathology, but also due to the global spread of bacterial plant diseases and the emergence of new bacterial diseases.
