Book Description
Begomoviruses are one of the most interesting plant viruses to study for basic and applied research as they cause huge economic losses to agriculture industries and farmers all over the world. They belong to family Geminiviridae and are emergent plant viral pathogens which cause diseases in various crops in the tropical and subtropical regions. They are transmitted by the whitefly (B. tabaci) and have either one (monopartite DNA-A) or two (bipartite DNA-A and DNA-B) genomic components. DNA-A and DNA-B are of ~2600 - 2800 nucleotides each. A number of serious diseases of cultivated crops of the Fabaceae, Malvaceae, Solanaceae and Cucurbitaceae families are caused by Begomoviruses which are considered as threat to their cultivation in many countries. Accurate diagnosis is important for successful diseases management, since plants infected by Begomovirus do not recover, suffer serious yield losses and act as further sources of inoculum, which is then picked up and spread by their vector whitefly (B. tabaci). Reports of occurrence of new viruses and re-emergence of several known viruses in new niches have become regular event. In such a dynamic system, growth of several crop species relies on an accurate diagnosis, management and better understanding of the biology of the casual virus. This is crucial to evolve appropriate control practices and to prevent the virus infection. Researchers have achieved considerable progress in characterization, detection and management of virus on different crop species in the last decade. This book covers latest information in diagnosis of begomoviruses in the present scenario and explores the new vistas in the field of genomics and proteomics. Chapters in Section 1 illustrates the occurrence, genome organisation, transmission and diagnostics of begomoviruses. It also details the diseases caused by begomoviruses on different crops, detection techniques and management strategies in support of research findings by presentation of data, graphics, figures and tables. Section 2 is a chapterwise collection of occurrence, diversity and status of begomoviruses in Asian Africa counties where the diseases are most prevalent. This book will provide wide opportunity to the readers to have complete information and status of begomovirus in Asia and Africa. This will be useful resource for researchers and extension workers involved in the begomvirus disease diagnosis and molecular biology. Expert detection, accurate diagnosis and timely management play a significant role in keeping plants free from pathogens. In this book expert researchers share their research knowledge and literature which are vital towards the diagnosis of begomoviruses, addressing traditional plant pathology techniques as well as advanced molecular diagnostic approach. The book deals with the economically important crops including fruits, vegetables along with challenges in crop protection against diseases caused by begomovirus. This will be resourceful and handy for researcher, practitioners and also students.

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 describes interactions of plant viruses with hosts and transmission vectors in an agricultural context. Starting with an overview of virus biology, economics and management, chapters then address economically significant plant diseases of tropical and subtropical crops. For each disease, symptoms, distribution, economic impact, causative virus, taxonomy, host range, transmission, diagnostic methods and management strategies are discussed.

Book Description
Increased agricultural productivity is a major stepping stone on the path out of poverty in sub-Saharan Africa and South Asia, but farmers there face tremendous challenges improving production. Poor soil, inefficient water use, and a lack of access to plant breeding resources, nutritious animal feed, high quality seed, and fuel and electricity-combined with some of the most extreme environmental conditions on Earth-have made yields in crop and animal production far lower in these regions than world averages. Emerging Technologies to Benefit Farmers in Sub-Saharan Africa and South Asia identifies sixty emerging technologies with the potential to significantly improve agricultural productivity in sub-Saharan Africa and South Asia. Eighteen technologies are recommended for immediate development or further exploration. Scientists from all backgrounds have an opportunity to become involved in bringing these and other technologies to fruition. The opportunities suggested in this book offer new approaches that can synergize with each other and with many other activities to transform agriculture in sub-Saharan Africa and South Asia.

Book Description
This book offers a comprehensive guide to the identification, detection, characterization, classification and management of plant pathogens and other beneficial microbes in agriculture. The science of plant pathology is a dynamic field and, given the growing interest in sustainable agricultural practices, plant disease management has also gained importance. Further, there has been a shift from traditional chemical-based methods to eco-friendly integrated disease management strategies with a greater focus on bio-control and other eco-friendly technologies. This book provides a comprehensive and timely account of latest concepts and advances in the field of plant pathology, including detection and diagnosis, host resistance, disease forecasting and plant biotechnological approaches. Accordingly, it will be of great interest to academics and all stakeholders working in the fields of plant pathology, microbiology, biotechnology, plant breeding, and other life sciences.
