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.

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 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 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 Brassica Biofumigation for Management of Rice Sheath Blight Caused by Rhizoctonia Solani AG 1 1A written by Maxwell Handiseni and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sheath blight caused by Rhizoctonia solani is one of the most important rice disease that can cause significant losses in grain yield and quality in the United States. Current management options for sheath blight consist of fungicides, tolerant cultivars and cultural practices. These options are not always very effective. Brassica plants have been used for soil fumigation to manage a variety of soilborne pathogens. Eleven plant species comprising of six Brassica juncea cultivars (Brand 199, Ruby Streak, Florida Broadleaf, Green wave, Red giant and Sheali Hong), two Brassica rapa cultivars (Southern Green and Napa), Brassica oleracea, Eruca sativa and Crotalaria juncea were evaluated for their efficacy on R. solani mycelia inhibition with or without soils collected from Texas, Arkansas or Mississippi rice fields. Evaluation of allyl isothiocynates (AITC) emission during the process of biofumigation was achieved by mixing B. juncea plant tissue at a rate of 0.25 or 0.5% (wt/wt) with either natural soil or pasteurized soil. The impacts of B. juncea soil amendment on the viability, aggressiveness, and sclerotia formation of R. solani AG1-1A was evaluated. B. juncea cover crop was integrated with host resistance and fungicide application to evaluate impact on rice sheath blight severity and rice yield. Four B. juncea cultivars (Brand 199, Ruby Streak, Florida Broadleaf, Green wave) consistently provided the greatest inhibition in all the soil types tested. Mycelial inhibition increased with an increase of B. juncea application rate. Plant tissue mixed with natural soils resulted in significantly higher AITC emission than in pasteurized soils. B. juncea amendment reduced numbers of sclerotia formed from the mycelium exposed to soils amended with B. juncea. Viability and aggressiveness of sclerotia or mycelium was reduced in soils amended with 3.2 % (wt/wt) of B. juncea. B. juncea cover crop significantly lowered sheath blight severity in all three years and led to a significantly higher grain yield in 2013 as compared to the fallow control. B. juncea cover cropping can be added to the rice disease management practices to enhance the efficacy of the current integrated pest management program for sustainable control of sheath blight in rice.
