This book was released on 2004-10-14 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study attempt was made to develop enzymatic and immunological methods for qualitative and quantitative detection of Septoria tritici and Stagonospora nodorum, which cause blotch diseases of wheat. Production of hydrolytic enzymes of both fungi was studied in vitro and in planta. Fungicide effects on Septoria leaf diseases by measuring enzyme activities were assessed, and specific fungicide effects as well as varietal resistances of wheat and triticale against S. tritici or S. nodorum were measured in field trials of two years by BA-ELISAs.

This book was released on 1985 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glume blotch of wheat, a disease incited by Septoria nodorum (=Leptosphaeria nodorum), was monitored through a succession of surveys during the period 1982-84 in eastern Washington . Findings revealed that infection in wheat occurs soon after seeddling emergence . Infection levels, varying upward of 70% in one of the two years, remained consistently high from November to March, declined somewehat in April-May and dropped dramatically in late May and June . It is speculated that such a decline is attributable to progressively fewer number of rainy days, lower relative humidities, shorter dew periods and elevating temperatures as the spring seasion advances . The viability of conidia of Septoria nodorum exposed on plastic strip underwent a corresponding decline with the advent of warmer, drier weather. The source of inoculum associated with the onset of the disease was linked to the presence of spore bearing pycnidia on debris of the previous wheat crop . The perfect stage of the fungus was never found on wheat or graminicolous hosts around and within wheat fields. Glume blotch effects on kernel weight of wheat was highly correlated with nodal infection . Substantial yield reduction ocurred when disease was imposed at the flowerig stage .According to criteria established by studying the relationship of organ infection and reduction in kernel weight it seemed unlikely that glume blotch is a disease of economic threat to the wheat industry in the Palouse. A new technique, involving the injection of inoculum into culms, was developed for evaluating cultivar reaction to glume blotch. A study of the survival of the fungus in hosts other than wheat indicated that downy chess (Bromus tectorum) may seerve as an effective alternative host. This host may play a role in the epidemiology of the disease in eastern Washington as well. Notwithstanding the results reported elsewhere, virulence of locally collected wheat isolates of Septoria nodorum, was not altered by ten consecutive passages through barley.

Book excerpt: Wheat Blast provides systematic and practical information on wheat blast pathology, summarises research progress and discusses future perspectives based on current understanding of the existing issues. The book explores advance technologies that may help in deciding the path for future research and development for better strategies and techniques to manage the wheat blast disease. It equips readers with basic and applied understanding on the identification of disease, its distribution and chances of further spread in new areas, its potential to cause yield losses to wheat, the conditions that favour disease development, disease prediction modelling, resistance breeding methods and management strategies against wheat blast. Features: Provides comprehensive information on wheat blast pathogen and its management under a single umbrella Covers disease identification and diagnostics which will be helpful to check introduction in new areas Discusses methods and protocol to study the different aspects of the disease such as diagnostics, variability, resistance screening, epiphytotic creation etc. Gives deep insight on the past, present and future outlook of wheat blast research progress This book’s chapters are contributed by experts and pioneers in their respective fields and it provides comprehensive insight with updated findings on wheat blast research. It serves as a valuable reference for researchers, policy makers, students, teachers, farmers, seed growers, traders, and other stakeholders dealing with wheat.
Download or read book Wheat Diseases and Their Management written by Yeshwant Ramchandra Mehta and published by Springer. This book was released on 2014-08-13 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat Diseases and Their Management addresses biotic and abiotic constrains to wheat production. Besides detailed illustrations and descriptions of the most important diseases of wheat in the world, it offers an updated view on the reemergence of some old diseases and the occurrence of new races of the pathogen. It deals with the sustainability of wheat production through precision agriculture and focuses on the importance of conservation tillage. The book also deals with pillars of integrated disease management which would be eco-friendly and reduce severity of diseases and yield losses, with acquired Latin-American experiences of more than 40 years.
Download or read book Current Trends in Plant Disease Diagnostics and Management Practices written by Pradeep Kumar and published by Springer. This book was released on 2016-04-28 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant diseases play an important role on our daily lives. Most of plant diseases are visible and are caused by biotic and/or abiotic factors. Symptoms are usually the results of a morphological change, alteration or damage to plant tissue and/or cells due to an interference of the plant’s metabolism. All basic structures of vascular plants are subject to attack by pathogens. The failure in accurate disease diagnosis and management may lead to huge losses in plant production and related commodities, which causes nutritional food scarcity. Typically, the appearance of a biotic symptom will indicate the relatively late stage of an infection and/or colonization of a pathogen. Expert detection, accurate diagnosis, and timely management play a significant role in keeping plants free from pathogens. In this book expert scholars share their research knowledge and key literature which are vital toward the diagnosis of plant diseases across the globe, addressing traditional plant pathology techniques, as well as advanced molecular diagnostic approach.
Download or read book Experimental Techniques in Plant Disease Epidemiology written by Jürgen Kranz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most books on epidemiology have treated the subject from a statistical, mathematical or computer applicational point of view. However, experiments must be performed first to provide the data for models which in turn can then be proven by further experimentation. This mutual interplay of theory and empirics gives epidemiology its scientific thrust and charm. This book provides a choice of methods for varying applications and objectives, covering all important aspects for the designing of experiments. Furthermore, the reader is supplied with solutions to his experimental problems and many "tricks of the trade". The newcomer to the field will also profit by this methodology guide.
