Download or read book Sheath Blight Disease of Rice written by K. Manibhushan Rao and published by Daya Books. This book was released on 1995 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sheat blight (ShB) is considered as one of the serious diseases of rice in Asian countries and the USA. The increase in ShB incidence is largely due to changes in the rice cultivation methods as well as in the use of early-maturing, semi-dwarf, high-yielding and N-responsive cultivars. Against this background, this monographic study is aimed primarily presenting the status of our knowledge by compiling the literature available as well as the author s own experience on rice diseases over three decades. The book is meant primarily for the graduate students, rice pathologists and extension workers. This compendium should not only stimulated further research but also will be used for ShB management. It traces the history of the disease, the casual agents, its nomenclature, taxonomy, morphology, physiology, variability, histopathology and ultra structure. It is profusely illustrated with excellent plates and number of tables which project the current status in a better way. Also information has been given on the disease management by induced resistance as well as biocontrol and the future resistance as well as biocontrol and the future perspectives on this important rice disease.

Download or read book Biological Control of Rice Diseases written by Samuel S. Gnanamanickam and published by Springer Science & Business Media. This book was released on 2009-07-14 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is suf?cient need to document all the available data on biological control of rice diseases in a small volume. Part of this need rests on the global importance of rice to human life. In the ?rst chapter, I have tried to show that rice is indeed life for most people in Asia and shortages in production and availability can lead to a food crisis. While rice is cultivated in most continents, biological disease management attains special relevance to rice farmers of Africa, Asia, and also perhaps, Latin America. These farmers are resource-poor and might not be able to afford the cost of expensive chemical treatments to control devastating rice pathogens such as Magnaporthe oryzae (blast), Xanthomonas oryzae pv. oryzae (bacterial leaf blight), Rhizoctonia solani (sheath blight) and the virus, rice tungro disease. In an earlier volume that I developed under the title, Biological Control of Crop Diseases (Dekker/CRC Publishers, 2002), I included transgenic crops generated for the management of plant pathogens as biological control under the umbrella of a broad de?nition. Dr Jim Cook who wrote the Foreword for the volume lauded the inclusion of transgenic crops and induced systemic resistance (ISR) as a positive trend toward acceptance of host plant resistance as part of biocontrol. I continue to subscribe to this view.

Download or read book A Toolbox for Managing Blast and Sheath Blight Diseases of Rice in the United States of America written by Yulin Jia and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice blast disease caused by the fungus Magnaporthe oryzae and rice sheath blight disease caused by the fungus Rhizoctonia solani are two major hurdles for stable rice production worldwide. Presently, fungicides are still needed to manage these two devastating fungal pathogens. After two decades of research efforts, a toolbox has been assembled with the following components: (1) insight into pathogen genomic identity and pathogen avirulence (AVR) genes that can be used to enhance plant breeding; (2) new mapping populations and germplasm and genetic stocks that can be used as starting materials to identify effective host resistance (R) genes; (3) user-friendly disease evaluation methods that can be used to accelerate the identification and utilization of R genes; (4) validated effective R genes that are readily available for improving genetic resistance; (5) host genetic markers that can be used to accelerate the development of new resistant germplasms/cultivars; and (6) an improved understanding of resistance mechanisms that can facilitate the engineering of resistance in commercial varieties. Appropriate employment of these tools in breeding and crop protection will reduce production costs and create an environmentally benign, sustainable rice production system.

Download or read book Biological Management of Rice Sheath Blight written by Ashraf Khan and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sheath blight of rice caused by Rhizoctonia solani Kuhn is one of the major production constrains of rice in most of rice growing countries of Asia. The management of sheath blight is a serious problem, since varieties resistant to disease are not available and use of chemical is limited due to pollution problem and high cost. Bioagents have been found effective in inhibiting growth of R. solani under in-vitro conditions. However, such organism fails to control the disease in the field due to various reasons. This book provides good information to identify various factors such as, effective isolates, time of application, mode, form and rate of bioagents, appropriate delivery system, right plant growth stage for application of bioagents, role of organic matter, soil pH, soil nutrition in effective biological management of rice sheath blight. References to the literature cited have been indicated throughout the text to obtain additional information. Bioagents are an important component of IPM as well as organic farming in modern agriculture. Therefore this book will be valuable and serve as source book to students, teachers, researchers and extension workers.

Download or read book Recent Advances in the Diagnosis and Management of Plant Diseases written by L.P. Awasthi and published by Springer. This book was released on 2015-11-19 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of the most challenging and significant chapters on the diagnosis and management of important bacterial, fungal, viral, viroid, phytoplasma, non parasitic diseases and various physiological disorders, in various crops. The chapters have been contributed by eminent plant pathologists, having wide experience of teaching and research on various crops with different types of diseases, which cause great economic losses. The book would be very useful for students, teachers and researchers of plant pathology. This book highlights recent advances made in the development of new types of resistance in host plants and alternative strategies for managing plant diseases to improve food quality and reduce the negative public health impact associated with plant diseases. Having entered into 21st century advancements in the Diagnosis of Plant Pathogens and Plant Disease Management need to be closely examined and adequately applied, so that newer challenges facing plant pathology could be adequately addressed in attaining food security for the growing population. Substantial advancements have been made in terms of expanding knowledge base of the biology of plant-microbial interactions, disease management strategies and application and practice of Plant Pathology. Application of molecular biology in Plant Pathology has greatly improved our ability to detect plant pathogens and in increasing our understanding, their ecology and epidemiology. Similarly, new technologies and resources have been evolved for the development of sustainable crop protection systems by different control strategies against various pests and pathogens that are important components of the integrated pest management programme. Natural products and chemical compounds discovered as a result of basic research and molecular mechanisms of pathogenesis have led to the development of “biorational” pesticides. Biological control has been found to be the most significant approach to plant health management during the twentieth century and promises using modern biotechnology, to be even more significant in the twenty-first century.
Download or read book Advances in Genetics Genomics and Control of Rice Blast Disease written by Xiaofan Wang and published by Springer Science & Business Media. This book was released on 2009-03-01 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice blast, caused by the fungal pathogen Magnaporthe grisea, is one of the most destructive rice diseases worldwide and destroys enough rice to feed more than 60 million people annually. Due to high variability of the fungal population in the field, frequent loss of resistance of newly-released rice cultivars is a major restraint in sustainable rice production. In the last few years, significant progress has been made in understanding the defense mechanism of rice and pathogenicity of the fungus. The rice blast system has become a model pathosystem for understanding the molecular basis of plant-fungal interactions due to the availability of both genomes of rice and M. grisea and a large collection of genetic resources. This book provides a complete review of the recent progress and achievements on genetic, genomic and disease control of the disease. Most of the chapters were presented at the 4th International Rice Blast Conference held on October 9-14, 2007 in Changsha, China. This book is a valuable reference not only for plant pathologists and breeders working on rice blast but also for those working on other pathysystems in crop plants.
