Mycoplasma Diseases of Crops

Plant Virus and Viroid Diseases in the Tropics


Book Description

Plant virus and sub-viral pathogens pose severe constraints to the production of wide range of economically important crops worldwide. The crops raised both through true seed and vegetative propagated materials are affected with number of virus and virus-like diseases. The virus may enter into plants through seed planting materials or by vectors. Once the virus is in the field, it multiplies and spreads following definite patterns depending upon the nature of the vector and agro-meteorological conditions. Disease free crops and plants are great economic and social importance in feeding the world's population. Detection of virus and sub-viral agents at initial stages of infection is critical to reduce economic losses. For nearly two decades, ELISA and its variants played a major role in large scale virus testing and also in the production of virus-free planting materials.




Plant Pathology in India


Book Description

The book makes a modest attempt to highlight the major achievements. The first chapter highlights the status of plant pathology in India before 1905 and sets the stage for an overview of the developments made in the last 100 years. Chapters on significant achievements and current status of knowledge has been contributed by leading experts on mycology, bacteriology, virology and nematology, and also on epidemiological research, fungicide research, biological control, host plant resistance against pathogens and on the application of biotechnological approaches for management of plant diseases. This covered the major broad areas of research in plant pathology. Besides, non conventional chapters encompassing the areas of international co-operation, policy issues and uncommon opportunities are also included along with the role of professional societies of plant pathology in India. Though the volume by no way is a complete account of the vast ocean of information available on various aspects of the subject, it is anticipated that the diverse areas covered in this volume will serve as a roadmap for the younger generation of plant pathologists and policy makers alike who have greater challenges ahead to resolve the pathological problems for augmenting production, ensuring bio-security and facilitating trade in under the changing global trade regime.




Plant Pathology (Pathogen and Plant Disease)


Book Description

• The book is revised according to the latest UGC syllabus and caters to graduate and postgraduate students of all Indian Universities.The book is also used to serve as a laboratory manual. • The matter is presented in simple langauge with well-illustrated and self-explanatory diagrams and photographs. • A new chapter on Biopesticides in Disease Management has been added. • Multicoloured photographs showing symptoms of various plant diseases have been included.







Virus and Virus-like Diseases of Major Crops in Developing Countries


Book Description

It appears that a comprehensive and up-to-date book on the impact of virus diseases on the major crops in developing countries is now much needed, especially as there have been rapid advances in the biological and molecular characterization and detection of the pathogens and possible approaches for their control. On the other hand, the economic losses caused by many of these diseases are tremendous and much of the accumulated knowledge to diminish the crop losses has not filtered through, or cannot be applied. This book is focused on the important crops. Each chapter on a specific crop will include inter alia, geographical distribution, the viruses - symptoms, damage, detection - a brief description of the viruses concerned, and present and future ways for their control. Experts from India, Nigeria, UK, USA, France, Germany, Peru, Japan, Australia, Netherlands, Venezuela, Kazakhstan and Israel (many of them from the International Research Institutions) have contributed chapters to this book.




Plant Diseases Of Viral, Viroid, Mycoplasma And Uncertain Etiology


Book Description

The adverse impact of plant diseases is felt around the world. In this book, the contributors analyze the nature and origins of pathogens that affect some economically important food and fiber crops.




A Century of Plant Virology in India


Book Description

The book is a compilation of research work carried out on plant viruses during past 100 years in India. Plant viruses are important constraints in Indian agriculture. Tropical and sub-tropical environments and intensive crop cultivation practices ideally favours perpetuation of numerous plant viruses and their vectors in India, which often cause wide spread crop losses. Of all the plant pathogens, studies of plant viruses have received a special attention as they are difficult to manage. A large body of literature has been published on the plant virus research from India during past 100 years; however the information is so far not available in one place. This book provides comprehensive information on the biology, molecular biology, epidemics, crop losses, diagnosis and management of viruses and viroids occurring in India. Description of properties of the viruses are provided in the chapters comprising of different genera such as Allexivirus, Begomovirus, Babuvirus, Badnavirus, Carlavirus, Carmovirus, Cucumovirus, Closterovirus, Ilavirus, Mandrivirus, Potyvirus, Tospovirus, Tungrovirus and Sobemovirus. Virus-vector research related to aphid, thrips and whitefly is discussed. The work on the management aspects of plant viral diseases has been described with reference to the conventional, antiviral and transgenic approaches. Further, the quarantine mechanism developed in India for the exclusion of viruses and vectors has also been included. The book also provides useful information about the capacity building on the research and education on Plant Virology in India. Overall, the book covers a wide range of accounts of research findings and innovations in Plant Virology in India during past 100 years. The book will be a resourceful reference to the students, scientists, agricultural professionals and policy makers.
