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 Sheath Rot Disease of Rice written by K. Manibhushan Rao and published by Daya Books. This book was released on 1996 with total page 110 pages. 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.

This book was released on 2012 with total page 942 pages. Available in PDF, EPUB and Kindle. Book excerpt: No systematic studies of the Rhizoctonia species and subspecies associated with rice sheath blight (ShB) in Arkansas have been conducted, and few studies have examined the genetic diversity of the rice ShB pathogen Rhizoctonia solani Kuhn AG 1 - IA. The objectives of this research were to assess the genetic diversity and the virulence/aggressiveness of isolates of R. solani AG 1 - IA and related Rhizoctonia spp. by specific PCR markers and sequence analysis of the ITS, RPB2 and beta-tubulin genes. Among the isolates examined, a considerable level of inter- and intra-specific variation was identified based on the molecular markers and differences in pathogenicity and pathogenicity/virulence on rice, soybean and tomato. There was significant correlation between the levels of virulence in the different crops. However, no correlation between pathogenicity/virulence differences and genotypic diversity was found. An in-depth genotypic analysis of the R. solani AG 1 - IA population from Arkansas was conducted using a multilocus sequencing analysis and SSR diversity indicated a high level of genotypic diversity and a significant degree of inbreeding. These data fit population structure with a mixed model of reproduction in which some extent of recombination (sexual/parasexual recombination) may occur, followed by clonal expansion of the fittest clones. The third objective of this study was to examine the production of specific toxins among isolates of R. solani and related species, and assess its correlation with pathogenicity/virulence. The ability to produce toxin was assessed by the presence of a signature peak in high pressure liquid chromatography (HPLC) and rice-leaf infiltration assays. Results suggested that no clear correlation exists between the capacity of an isolate to produce toxin in vitro, the ability of the toxin to cause necrosis in susceptible host tissue in an infiltration bioassay, and the capacity of the isolate to cause disease in greenhouse inoculation tests. These support the hypothesis that R. solani AG 1 - IA phytotoxin is a virulence factor with a minor contribution in disease development. The resistance to rice ShB is a polygenic and quantitative trait, and no immunity has been identified. A final objective was to map for potentially new quantitative trait loci (QTL) associated with resistance to ShB (SB-QTLs) in a population derived from a cross of two elite Indica cultivars, 'Fedearroz2000' and 'Palmar'. Results identified one significant SB-QTL with LOD > 3.0 on chromosomes 9, and three significant SB-QTLs with 1.5
