Book Description
Pathogens, Vectors, and Plant Diseases: Approaches to Control is a collection of papers that discusses how vector host interactions, vector ecology, and disease epidemiology can be applied to disease prevention and control. The book deals with innovative strategies pertaining to control of vector-borne viruses and viral infections in plants. One paper discusses nonpesticidal control of vector-borne viruses including soil solarization that uses solar energy for crop protection, and insect sterilization through radiation, chemosterilants or genetic modifications. Another paper discusses chemicals that interfere with nucleic acid and protein synthesis; as these interactions pose no hazards to animal (mammals), the chemicals are suitable for controlling viral diseases. One author examines the use of oil sprays and reflective surfaces as a means of controlling plant viruses transmitted by insects. In the United States, the entry of vector-borne plant pathogens is controlled by plant quarantine. One author lists several ways in effective quarantine procedures, as well as, the safe importation of potential vectors as cultures. This book is suitable for environmentalists, biologists, conservationists, agriculturists, botanists, and researchers in botany and plant genealogy.

Book Description
The papers contained in this book were presented at a NATO Advanced Research Workshop (ARW) held at Cape Sounion, Athens, Greece, 19-24 May, 1991. The twenty-eight more comprehensive papers represent the key subjects of the ARW covered by invited speakers. The thirty-four short papers pre sented in a research format are contributions of those invited to participate in the ARW. There was a total of 70 participants from 21 countries. The objectives of the ARW were as follows: to review current knowledge of biological control of plant diseases and plant parasitic nematodes, with emphasis on mechanisms at the molecular, cellular, organismal, and ecosystem level; to examine and expand on current concepts and synthesize new concepts; to identify and prioritize limitations in the use of biological control for plant diseases and nematodes and the scientific research needed to overcome these limitations; and to develop strategies for biological control through management of resident agents or introduction of natural or modified agents.

Book Description
Considerable advances have been made in the treatment of antiviral diseases over the last decade. Several new drugs have been introduced while new clinical information has been gathered on the efficacy of existing drugs. This study aims to provide an examination of the basic science (drug formulae, structure and biochemical activity) and clinical information (usage and efficacy) on chemotherapy, as well as describing future potentials.

Book Description
This book is a compilation of the most challenging and significant chapters on the diagnosis and management of important bacterial, fungal, viral, viroid, phytoplasma, non parasitic diseases and various physiological disorders, in various crops. The chapters have been contributed by eminent plant pathologists, having wide experience of teaching and research on various crops with different types of diseases, which cause great economic losses. The book would be very useful for students, teachers and researchers of plant pathology. This book highlights recent advances made in the development of new types of resistance in host plants and alternative strategies for managing plant diseases to improve food quality and reduce the negative public health impact associated with plant diseases. Having entered into 21st century advancements in the Diagnosis of Plant Pathogens and Plant Disease Management need to be closely examined and adequately applied, so that newer challenges facing plant pathology could be adequately addressed in attaining food security for the growing population. Substantial advancements have been made in terms of expanding knowledge base of the biology of plant-microbial interactions, disease management strategies and application and practice of Plant Pathology. Application of molecular biology in Plant Pathology has greatly improved our ability to detect plant pathogens and in increasing our understanding, their ecology and epidemiology. Similarly, new technologies and resources have been evolved for the development of sustainable crop protection systems by different control strategies against various pests and pathogens that are important components of the integrated pest management programme. Natural products and chemical compounds discovered as a result of basic research and molecular mechanisms of pathogenesis have led to the development of “biorational” pesticides. Biological control has been found to be the most significant approach to plant health management during the twentieth century and promises using modern biotechnology, to be even more significant in the twenty-first century.

Book Description
Handbook of Plant Virus Diseases presents basic information about viral-caused and viral-like diseases in many cultivated crops. The editors, internationally known plant pathologists, provide authoritative descriptive symptomatic signatures of virus diseases, to aid in the diagnosis and possible control of viruses. This handbook organizes cultivated plants into groups according to their final destinations and uses after harvest-a useful grouping system that indicates that some diseases, their resultant epidemiology, and control measures are characteristic within different groups.

Book Description
Around the globe, besides fungal and bacterial diseases, both virus and viroid diseases have acquired greater importance in the realm of plant pathology and call for effective management measures as they are responsible for heavy yield losses and are a matter of vital importance and concern to farmers, horticulturists, gardeners and foresters. Understanding disease epidemiology is of vital importance for formulating viable disease management practices in a given agro-ecosystem. The development and progress of plant disease epidemics are variable from region to region. Epidemiology is not a static process, but rather a dynamic course that varies with a change in the ecology, host, vector and virus systems.

Book Description
This book is intended to provide a substantive treatment of plant disease management for graduate and undergraduate students in which theoretical and practical elements are combined. Reference is made to specific diseases and control practices to illustrate basic principles or strategies. The section on epidemiology includes a chapter in which arthropod vectors (aphids, leafhoppers, whiteflies, Coleoptera and mites) are briefly discussed, and the section on control includes references to the use of crop varieties with resistance to such vectors, and also contains information on mechanical, cultural, biological and chemical measures that contribute to vector control. The technology of disease management is presented according to epidemiological principles. Sections on diagnosis, epidemiology, environmental factors, disease forecasting, disease control (exclusion, physical, chemical and biological), plant resistance, cultural modifications to suppress epidemics, effects of chemicals and their major groups and uses, and examples of disease management in practice are included. A bibliography and index are appended.

Book Description
Physiology of disease resistance is the most fascinating field of plant pathology. Plants have their own built in defence mechanisms against almost all microorganisms, but in a few cases the pathogen overcome the defence barrier with their offensive chemicals and cause diseases. It is a battle between microorganisms and plants, and sometimes the plants lose the battle. If the mystery of disease resistance is unraveled, scientists can engineer plants to win the battle even when the pathogens have an array of offensive chemicals. Several factors contribute to disease resistance and by identifying the links between different mechanisms, we may be able to alter host physiology to ward off the pathogens by connecting or disconnecting some of the vital links. This book critically analyses the various physiological and biochemical processes involved in the defence mechanisms of various crops such as rice, wheat, maize, sorghum, finger millet, tomato, potato, beans, cucumber, chilies, cotton, sugarcane, tobacco, apple, orange, grapevine, mango and banana against fungal, bacterial and viral diseases. It reviews all of the published works critically and suggests future course of research.
