This handbook contains 13 chapters covering banana (Musa and Ensete) diseases caused by various groups of causal agents and disorders caused by unknown and known factors. Topics discussed include fungal diseases of the foliage, root, corm, pseudostem, fruit (pre- and postharvest), as well as diseases caused by bacteria and phytoplasmas, viruses and nematode pathogens. Information is given on their economic impact, distribution, symptoms, disease cycle and epidemiology, host reaction, and control. Non-infectious disorders, mineral deficiencies, injuries caused by adverse climate and extreme weather, chemical injuries and genetic abnormalities are also described. Topic on quarantine and the safe movement of Musa germplasm is also given. This book, like the last, is for all 'banana doctors' around the world. It is hoped that it serves as a useful field and laboratory guide plus a source of information to all those investigating problems of the banana, abacá and enset crops.
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 diseases cause serious threats to the successful cultivation of horticultural crops, resulting in huge losses in their yields. These plant diseases are known to affect horticultural crops at various growth stages and reduce the yield as well as quality of fruits and vegetables. Diseases also cause subsequent postharvest transit and storage losses. This 4-volume set provides the latest diagnostic information along with effective management solutions to the problems of diseases of field crop plants caused by phytopathogens. In volume 1, each chapter includes an introduction, disease symptoms, causal organisms, disease cycles, epidemiology, and management of economically important plants. With contributions from national scientists who are engaged in teaching, research, and extension services who share their experiences here, the chapters explore apples, amla (or Indian gooseberry), avocado, Indian bael, banana, Indian jujube, citrus, grapes, guava, hazelnut, and more. The volumes provide an abundance of information for understanding and managing plant diseases, with emphasis on diagnostic techniques. The collection includes: Volume 1: Fruit Crops Volume 2: Vegetable Crops Volume 3: Ornamental Plants and Spice Crops Volume 4: Important Plantation Crops, Medicinal Crops, and Mushrooms
In a field of mature bananas, plants can be seen at all stages of vegetative growth and fruit maturity, providing a fascination for anyone who has an interest in growing crops. Banana farmers in the tropics can harvest fruit every day of the year. The absence of seasonality in production is an advantage, in that it provides a continuity of carbohydrate to meet dietary needs as well as a regular source of income, a feature that perhaps has been under-estimated by rural planners and agricultural strategists. The burgeoning interest in bananas in the last 20 years results from the belated realization that Musa is an under-exploited genus, notwithstanding the fact that one genetically narrow group, the Cavendish cultivars, supply a major export commodity second only to citrus in terms of the world fruit trade. International research interest in the diversity of fruit types has been slow to develop, presumably because bananas and plantains have hitherto been regarded as a reliable backyard source of dessert fruit or starch supplying the needs of the household, and in this situation relatively untroubled by pests, diseases or agronomic problems.
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.
