Annotation. Comprehensive information on diseases of the most important tropical fruit cropsChapters are devoted to a single or, in some cases, a related group of host plantsThe history, distribution, importance, symptoms, aetiology, epidemiology and management of diseases of each crop are described in detailThis book offers a comprehensive review of diseases of important tropical and some subtropical fruit crops. The history, distribution, importance, etiology, epidemiology and control of diseases of each host crop are covered, along with brief summaries on the taxonomy, origins and characteristics of each host. Additional information is given on the biology and pathology of the causal agents and on new advances that change or otherwise enhance our understanding of the nature and cause of these diseases. Plant pathologists, plantation and nursery managers, lecturers and those who are involved in tropical agriculture and horticulture will find this an essential reference.

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.

Horticulture in India is fast emerging as a major commercial venture, because of higher remuneration per unit area and the realization that consumption of fruits and vegetables is essential for health and nutrition. In the last one decade, export potential of horticultural crops has also significantly increased attracting even multinationals into floriculture, processing and value added products. Productivity of horticultural crops in India is relatively low as compared to other countries. Of the several factors responsible for lower productivity of horticultural crops, bacterial and viral/mycoplasmal/phytoplasmal diseases are considered as important limiting factors. Diseases of horticultural crops continue to cause losses of about 10% of the crop yields worth more than Rs. 15,000 crores annually. More than 9,600 MT of technical grade fungicides are used annually to manage the diseases in India. The information on bacterial and viral/mycoplasmal/phytoplasmal diseases of horticultural crops (fruits, vegetables, plantation, spice, tuber, ornamental, medicinal and aromatic crops) is very much scattered. There is no book at present which comprehensively and exclusively deals with the above aspects in horticultural crops. The present book deals with distribution, symptoms, host range, disease cycle, survival, spread, transmission and management of bacterial and viral/mycoplasmal/ phytoplasmal diseases in horticultural crops in detail using regulatory, physical, cultural, chemical, biological, host plant resistance and integrated methods. The book is extensively illustrated with excellent quality photographs enhancing the quality of publication. The book is written in lucid style, easy to understand language along with adoptable recommendations involving eco-friendly components of IDM. This book is a practical guide to practicing farmers of horticultural crops. Further, it is a useful reference to policy makers, research and extension workers and students. The material can also be used for teaching undergraduate and post-graduate courses.

As the oldest and largest human intervention in nature, the science of agriculture is one of the most intensely studied practices. From manipulation of plant gene structure to the use of plants for bioenergy, biotechnology interventions in plant and agricultural science have been rapidly developing over the past ten years with immense forward leaps on an annual basis. This book begins by laying the foundations for plant biotechnology by outlining the biological aspects including gene structure and expression, and the basic procedures in plant biotechnology of genomics, metabolomics, transcriptomics and proteomics. It then focuses on a discussion of the impacts of biotechnology on plant breeding technologies and germplasm sustainability. The role of biotechnology in the improvement of agricultural traits, production of industrial products and pharmaceuticals as well as biomaterials and biomass provide a historical perspective and a look to the future. Sections addressing intellectual property rights and sociological and food safety issues round out the holistic discussion of this important topic. Includes specific emphasis on the inter-relationships between basic plant biotechnologies and applied agricultural applications, and the way they contribute to each other Provides an updated review of the major plant biotechnology procedures and techniques, their impact on novel agricultural development and crop plant improvement Takes a broad view of the topic with discussions of practices in many countries

With contributions from more than 30 internationally renowned experts, this book combines coverage of theory with coverage of global practices. Highlighting the day-to-day challenges of organic crop management for cost-effective real-world application, the book explores the biological control of diseases in 12 major crops. It focuses on the use of host plant resistance through transgenics and induced systemic resistance as a part of biological control. Topics covered include the role of biocontrol agents for signalling resistance, effective ecofriendly alternative to combat bacterial, fungal, and viral infestation, and transgenic crops in disease management.

This book provides a practical guide to the commonly used detection methods for seed-transmitted viruses and viroids affecting both tropical and non-tropical crops. The first part describes important aspects of seed-transmitted viral diseases. The second and main part contains principles of the detection techniques and step-by-step protocols accompanied by method optimization and comments. Most of the described techniques can be equally applied to plant viruses and viroids other than seedborne ones. This book will be of significant interest to those working in seed testing laboratories and students and teachers within plant pathology and seed science.

The book presents a chronology of events of B. tabaci and geminiviruses, and an overview within the Caribbean and Latin America. The pathosystems involving Tomato yellow leaf curl virus, Cotton leaf curl virus and the cassava mosaic viruses are discussed. Data is presented on amino acid concentrations influencing B. tabaci and thus serves the basis for holidic diets. The essential molecular techniques for B. tabaci identification and classification are included with factors to consider for appropriate applications; an essential working guide for graduate students and researchers in the molecular field. Excellent photos portray symptoms of geminivirus-infecting crops: tomato, cotton, cassava, legumes and cucurbits; an important guide for researchers and growers. The novel insecticides, their mode of action and specificity; emphasize the applications of these within IPM programs.
