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.




Ganoderma Diseases of Perennial Crops


Book Description

Annotation. Diseases caused by Ganoderma species cause major losses of palms and other perennial crops throughout the world, and these are particularly significant in Asia. Successive replanting of crop monocultures can be rapidly exploited by soil borne fungi such as Ganoderma, and the problem will become more serious in the 21st century, as more areas become due for second or even third replanting. Environmental considerations will reduce exploitation of new forest areas, making further replanting of these crops inevitable. Thus, appropriate, integrated management systems for these diseases are vital. However, the development of such control measures has been hampered in the past by a limited knowledge of the nature and inter-relationships of populations of different hosts and the mechanisms of disease establishment and spread.This book aims to address these limitations through enhanced knowledge of the biology and taxonomy of Ganoderma species. The use of molecular and biochemical methods can be used to provide a greater understanding of the spread of the pathogen, and consequently, the improved management of disease.




Diseases of Tropical Fruit Crops


Book Description

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.







Control of Crop Diseases


Book Description

Explores current practical methods for disease control in field and protected crops and outlines recent advances in molecular techniques.




Pests of Crops in Warmer Climates and Their Control


Book Description

This is a textbook providing basic data about the crop pests and the damage they inflict throughout the tropics and sub-tropics. Each major pest is illustrated by either a line drawing or a photograph, and sometimes the damage can also be seen. A world distribution map is provided for each species. Control measures tend to be general rather than very specific. Most of the pests are insects and mites, but some nematodes, molluscs, birds and mammals are included.




Plant Protection in Tropical Root and Tuber Crops


Book Description

This book is a compilation of information on insect/mite/vertebrate pests and fungal/bacterial/viral/mycoplasma/nematode diseases of tropical root and tuber crops such as cassava, sweet potato, yams, taro, Amorphophallus, yam bean and tannia. The book highlights the distribution, symptoms and damage, biology, survival and spread of each pest and describes management methods. It also sheds light on different eco-friendly pest management strategies including physical, cultural, chemical, biological, host resistance and integrated methods. The book is written in a lucid style using easy-to-understand language and offers adoptable recommendations involving eco-friendly control measures. It serves as a useful reference source for policy makers, research and extension workers, practicing farmers and students. The material can also be used for teaching post graduate courses in state agricultural universities. .




Climate Change and Agriculture Worldwide


Book Description

In recent years, especially with the approach of the 21st Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change in Paris in late 2015, the number of publications, conferences and meetings on climate change has been growing exponentially. Yet uncertainties remain concerning rural tropical areas where models are forecasting the onset of multiple disorders and trends are unclear. Meanwhile, the impact of climate change on the poorest communities is regularly documented, often prompting alarmist reactions. How can food security be achieved while adapting to and mitigating climate change? What are the main threats to agriculture in developing countries? How do farmers in these countries cope with the threats? What does agricultural research propose? What options have yet to be investigated? A broad scope of scientific research is underway to address these challenges. Diverse solutions are available, including new agricultural practices, water management, agricultural waste recycling, diagnosis of emerging diseases, payment for ecosystem services, etc. Gaining insight into the financial and political mechanisms that underlie international climate negotiations is also essential to design practical ways to deal with climate issues and meet sustainable development requirements in collaboration with farmers. This book pools the wealth of experience of dozens of researchers and development officers from a range of disciplines. We have focused on making it detailed, accurate and hopefully easy to read for researchers, students and all other informed readers.




Viral Diseases of Field and Horticultural Crops
