Available in PDF, EPUB and Kindle. Book excerpt: Sheath rot (ShR) has been known almost for a century, but was restricted to South East Asia and the Indian Subcontinent. Occurrence of the disease became widespread in mid 1970s when the high yielding technology was introduced by planting improved N-responsive cultivars. Today, ShR is a major constraint in rice production in irrigated as well as rainfed, upland rice. The disease has been reported in many rice growing countries and its spread causes concern because of its transmission and dissemination. The causal fungi, Sarocladium spp, have biological association with rice tungro virus, mites, stem-borers and mealy bugs and therefore increases the ShR incidence as well as severe yield losses. Scant information is available on the biology of the causal organism both in vitro and in vivo. Although a few tall cvs have been identified as resistant, almost all the high-yielding, improved cvs are susceptible to ShR. Biology of the ShR pathogens, host range, varietal resistance and future perspectives were discussed and the importance for a holistic approach to disease control was emphasized.

Available in PDF, EPUB and Kindle. Book excerpt: Major Fungal Diseases of Rice: Recent Advances provides a comprehensive overview of latest research in rice fungal pathology. There are 25 chapters dealing with the blast, sheath blight, sheath rot, brown spot and scald diseases of rice as well as some broader topics. The book covers recent progress in a number of key fundamental aspects such as pathogenicity, pathogen diversity, molecular characterisation, gene cloning, genetics of host resistance and host-pathogen interactions. It also presents the current status and perspectives in strategic and applied areas such as epidemiology, resistance breeding, biological control, induced resistance, seed-borne diseases and quarantine issues and disease management strategies. This book is essential for rice researchers, pathologists and breeders and will also be suitable for cereal and plant pathologists in general, as there is an extensive coverage of recent research advances in rice blast, a model system in plant pathology.

This book was released on 2013-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice is the most widely consumed staple food for a large part of the world's human population. It is the grain with the second-highest worldwide production. It is the most important grain with regard to human nutrition and caloric intake, providing more than one fifth of the calories consumed worldwide by the human species. Rice production frequently faces formidable constraints due to biotic and abiotic stresses. Among the biotic stresses, sheath rot caused by Sarocladium oryzae has become endemic and one of the major constraints in production.The major aspects covered in this book include host range; predisposing factors;efficacy of botanicals, fungicides, insecticides and fungicide- insecticide combinations against sheath rot of rice; antagonistic effect of paddy phylloplane microflora against S. oryzae; screening of rice genotypes, characterisation of promising plant extracts against the disease; physiological alterations induced by plant extracts in the rice plants and changes in quality of rice grains due to infection. The book contains 44 tables, nine plates and two figures. It is an excellent book for researchers and post graduate students of Plant Pathology.

Download or read book Fungal Diseases of Rice and Their Management written by Deepti Srivastava and published by CRC Press. This book was released on 2024-01-09 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice is a widely consumed crop around the world that has tremendous importance and is cultivated almost everywhere except Antarctica. However, various biotic and abiotic stresses have a negative effect on rice cultivation, seriously reducing its yield. This volume examines the bacterial and fungal pathogens that cause rice diseases and explores how to manage these diseases. It covers the economic and environmental impact of rice fungal diseases on global food security and proceeds to delve into diagnostic methods for rice fungal pathogen detection and discusses current strategic and applied biotechnological methods for the effective management of rice fungal diseases.

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.
