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.
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.
Pepper Virome: Molecular Biology, Diagnostics and Management presents detailed information about the plant viruses that infect pepper worldwide, providing crucial insights for both the scientific community and producers. Understanding the nature of the viruses, their transmission methods and possible sources of resistance in order to minimize the yield losses as well as to reduce the spread of these viruses to new locations or countries is of global importance.Pepper is an important commodity worldwide. It is cultivated for both fresh produce and for processing industry as a spice. However, various diseases affect pepper production and cause significant yield losses in pepper yield. The increasing outbreaks of virus species infecting Capsicum spp. have become a major problem for growers. A combination of factors, including expansion and intensification of pepper cultivation, availability of volunteer hosts, abundance of insect vectors and climate change have all contributed to the issue. Pepper Virome provides in-depth information on both the viruses infecting peppers, and eco-friendly management measures to decrease the rate of spread of viruses. Addressing the need for increased international collaboration and exchange of pepper germplasm, these insights will also facilitate the selection and breeding for improved Capsicum spp. adapted to local conditions and uses. - Focuses on symptomatology, transmission, and epidemiology of pepper viruses - Reveals the impact on host, yield, and virus-vector interactions - Evaluates management strategies against viruses and how they have evolved
Crop protection is becoming increasingly important due to the need for food security and to meet growing environmental challenges. This new book, New Advances in Crop Disease Management, provides readers with an updated and comprehensive overview of diverse crop protection strategies with special emphasis on the recent advances in crop protection approaches, fundamental concepts, principles, methodology, relationships, and benefits for crop protection and human health. It covers a variety of disciplines such as plant pathology, biochemistry, cell, and molecular biology, plant physiology, host-pathogen interactions, precision agriculture, decision analysis, disease risk, new ways of exploiting host genetic diversity including host resistance deployment, biological control and microbial interactions, surveillance and detection technologies, and the consequences of climate change and signaling. The book contains twenty chapters and begins with the role of biotechnology and its implications in crop disease detection and protection. It then discusses the plant response to pathogen attack, molecular basis of host-pathogen interaction and induction of defense response, viz., R gene, phytoalexins, etc., and advancement in early detection methodologies. It also delves into induced mutation as new technology for resistant crop development. The last part details the recent approaches and applications of resistant crop lines development, including resistant pulses development approaches, mining and mapping of R genes, gene pyramiding, lactic acid bacteria as biocontrol agents, effecteromics and nanotechnology in crop disease management, and the applications of phytochemicals and CRISPR-Cas in the development of disease resistant crops for future. New Advances in Crop Disease Management will be a key reference in the field of crop science and plant pathology, agriculture for faculty and industry professionals as well as a valuable textbook/reference for undergraduate and graduate students.
Grain legumes, together with quinoa and amaranth (pseudocereals) and other crops are attractive candidates to satisfy the growing demand for plant protein production worldwide for food and feed. Despite their high value, many protein crops have not been adequately assessed and numerous species are underutilized. Special attention has to be paid to genetic diversity and landraces, and to the key limiting factors affecting yield, including water deficiency and other abiotic and biotic stresses, in order to obtain stable, reliable and sustainable crop production through the introduction and local adaptation of genetically improved varieties. Legumes, the main protein crops worldwide, contribute to the sustainable improvement of the environment due to their ability to fix nitrogen and their beneficial effects on the soil. They play a key role in the crop diversification and sustainable intensification of agriculture, particularly in light of new and urgent challenges, such as climate change and food security. In addition, the role of legumes in nutrition has been recognized as a relevant source of plant protein, together with other benefits for health. Chapters dealing with common bean, lupine, soybean, lentil, cowpea and Medicago are included in this book. Most contributions deal with legumes, but the significant number of papers on different aspects of quinoa gives an idea of the increasing importance of this protein crop. Pseudocereals, such as quinoa and amaranth, are good sources of proteins. Quinoa and amaranth seeds contain lysine, an essential amino acid that is limited in other grains. Nutritional evaluations of quinoa indicate that it constitutes a source of complete protein with a good balance among all of the amino acids needed for human diet, and also important minerals, vitamins, high quality oils and flavonoids. Other protein crops also included in this book are hemp, cotton and cereals (maize, wheat and rice). Although cereals protein content is not high, their seeds are largely used for human consumption. In this book are included articles dealing with all different aspects of protein crops, including nutritional value, breeding, genetic diversity, biotic and abiotic stress, cropping systems or omics, which may be considered crucial to help provide the plant proteins of the future. Overall, the participation of 169 authors in 29 chapters in this book indicates an active scientific community in the field, which appears to be an encouraging reflect of the global awareness of the need for sustainability and the promising future of proteins crops as a source of food and feed.
