Knowledge of downy mildew pathogens and diseases has increased significantly in taxonomy, phylogeny, genetics, molecular biology, host-parasite interactions, ecology, epidemiology and control. The opportunity to update comprehensively the major advances in these areas was created by the 2nd International Symposium on Downy Mildews held in July 2007 at Olomouc (Czech Republic). Keynote contributions from this meeting are published here in 14 chapters that provide the most authoritative and recent analysis of these biotrophic plant pathogens and their interactions with plants. It will be an invaluable resource to students and researchers in plant pathology, mycology, taxonomy, plant biology and crop protection.

This book introduces the nature, causes and impact of plant diseases, describes briefly the history of plant pathology as a scientific discipline, and introduces the disease cycle as the key tool for understanding disease development and devising appropriate management strategies. The book describes the diverse organisms and agents that cause diseases—plant pathogens. Print edition not for sale in India.

The book reviews key developments in downy mildew research, including the disease, its distribution, symptomatology, host range, yield losses, and disease assessment; the pathogen, its taxonomy, morphology, phylogeny, variability, sporulation, survival and perpetuation, spore germination, infection, pathogenesis, seed infection, disease cycle, epidemiology, forecasting, and fine structures. The book also elaborates the mechanisms of host resistance (biochemical, histological, genetic, and molecular, including cloning and the mapping of R-genes), disease resistance breeding strategies, and the genetics of host-parasite interactions. It explores disease management based on cultural, chemical, biological, host resistance, and integrated approaches; and provides suggestions for future research areas. This book offers a comprehensive guide to an economically important disease, reviewing in detail the extant body of literature. Divided into 16 chapters, each of which includes a wealth of photographs, graphs, histograms, tables, figures, flow charts, micrographs etc., it represents an invaluable source of information for all researchers, teachers, students, industrialists, farmers, policymakers, and all others who are interested in growing healthy and profitable cruciferous crops all over the world.

Security sensitive microbes (viruses, bacteria, fungi, and parasites) and toxins, which are often referred to as the select agents and toxins, have the capacity to cause serious illness and death in humans, animals, and plants. Throughout history, these microbes and toxins have been exploited in one form or another as biowarfare and bioterror agents that create fear and panic well beyond any actual physical damages they might cause. Manual of Security Sensitive Microbes and Toxins provides comprehensive, state-of-the-art coverage of microbes and toxins of biosecurity concern. The ultimate goal is to increase our awareness of these agents and enhance our preparedness against any future bio-emergencies. The book begins with an introduction containing a brief overview of the historical aspects of security sensitive microbes and toxins. This is followed by a concise summary of the current status in relation to the regulation of security sensitive microbes and toxins and a discussion of future development trends. The book is divided into seven parts: Microbes and Toxins Affecting Humans and Animals: Viruses Microbes and Toxins Affecting Human and Animals: Bacteria Microbes and Toxins Affecting Human and Animals: Fungus and Parasite Microbes and Toxins Affecting Human and Animals: Toxins Microbes Affecting Animals: Viruses Microbes Affecting Animals: Bacteria Microbes Affecting Plants Written by experts in the relevant areas of research, the chapters are authoritative reviews, each one covering a single microbe or toxin with respect to its classification, biology, epidemiology, pathogenesis, identification, diagnosis, treatment, and prevention. The chapters also discuss the limitations of our current knowledge and challenges relating to improved detection and control of the microbe or toxin.

This book presents an unprecedentedly thorough collection of information on the diseases of cultivated annual oilseed crops, including peanut, rapeseed-mustard, sesame, soybean, sunflower, and safflower. It covers and integrates global literature on the subject up to 2014, setting it apart from other books that are only of regional importance. The authors are internationally recognized experts who have compiled decades of information from previously scattered research into a single volume that provides much-needed updates to oilseed crop disease research.

This volume offers a comprehensive coverage of the general principles and recent advances in fungicide resistance. It describes the development, mechanisms, monitoring, and management of resistance and covers the most important group of fungicides that have caused resistance on various crops. An historical review of fungicide resistance over the past 40 years sets the scene for up-to-date basic information on mode of action, as well as the genetics, mechanisms, and evolution of resistance. Monitoring for resistance, including the latest developments in molecular diagnostics, moves readers into the practical aspects of resistance management, which is dealt with through a series of case studies outlining fungicide-use strategies on several key crops. The chapters reflect the experience of authors internationally recognised for their significant contributions to fungicide resistance research. The majority of crop diseases are caused by fungal pathogens, and disease control relies heavily on chemically synthesized fungicides. However, modern fungicides often encounter the problem of resistance development in target pathogens. Thus pathogen resistance to fungicides is an important factor that causes loss of yield and quality of crops. It often threatens biosecurity through the decrease of fungicide efficacy in the fields. To manage fungicide resistance successfully will require the promotion of integrated disease management, involving not just chemical fungicides, but also host plant resistance, agronomic factors, and reliable biological control agents where these are available. Well referenced throughout, the book offers a comprehensive account of resistance, which will be useful as a source of material for lecturers and for both industrial and academic scientists involved in fungicide resistance research. It is also a valuable sourcebook for students.
