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.

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 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.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope of this study was the selection of bacterial strains from rice and maize and evaluation of their potential for plant growth promotion and biological control of rice diseases. 103 bacterial strains isolated from roots, rhizosphere and soil of rice and maize were assayed for production of siderophores, antibiotics, hydrolytic enzymes and HCN. From these, 33 strains were found to produce siderophores, eight were capable of producing diffusible antibiotics and four produced volatile antibiotics, while only one strain was found to produce HCN. Dual culture antagonistic assays were used to select strains capable of inhibiting growth of three major rice pathogens, Xanthomonas oryzae pv. oryzae (bacterial blight), Rhizoctonia solani (sheath blight) and Magnaporthe grisea (rice blast). When inoculated into soils, a number of strains suppressed the incidence of rice blast and sheath blight diseases in two different rice varieties. A strong correlation between siderophore production and in vitro antagonism was found, which extended to biocontrol assays for rice blast disease in the variety Super Basmati, but not Azucena, suggesting that bacterial strains use different mechanisms in suppressing the same pathogen in different rice varieties. As there was no direct contact between the pathogen and bacterial strains, the proposed mechanism for disease suppreSSIOn is induced systemic resistance (ISR). Gene expression analysis for sheath blight experiments confirmed the enhanced induction of chitinase IIb and the peroxidase P0X22.3 by selected bacterial strains. Selected bacterial strains from rice were also observed to enhance plant growth and yield, and this may be related to their ability to fix nitrogen (detected by acetylene reduction assay), solubilize phosphates and/or produce auxin. This study led to the isolation, selection and evaluation of potentially useful bacterial strains from rice and maize that were genetically diverse and persistently abundant in the rhizosphere and can be further utilized for integrated pest management of rice. Moreover, as these strains are . also capable of improving plant health and enhancing grain yield, they could be further utilized either individually or in consortia for integrated nutrient management of rice and maize.
