This book was released on 2013-09-07 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusarium head blight (FHB) on small-grain cereals is one of the most devastating diseases. Several species can cause head blight, though Fusarium graminearum is the predominant pathogen in most regions. F. graminearum is one of the most intensively studied fungal plant pathogens. This book presents the current state of knowledge regarding mycological aspects that make wheat-Fusarium interaction, such as hyphal growth, morphogenesis in germinating spores, visualization of enzymatic hydrolysis, production of mycotoxins, inhibition of the hyphal growth by antagonist microorganisms, use of natural substances or by modification of the host resistance, as well as genetic analysis and expression of genes that regulate the infection. Fungal ecology and epidemiology will also be discussed. Just as the analysis of environmental requirements for the establishment of the disease, the use of forecasts of disease risk with meteorological base and integrated management and control. This book includes the study of disease in Latin America, therefore will be of interest to researchers who are working on the issue, as for those who are interested in knowing about the disease.

This book was released on 2014 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Fusarium head blight (FHB) or head scab, caused predominantly by Fusarium graminearum in North America, is a disease of economic importance in wheat (Triticum aestivum L.) in Ohio and other parts of the world. FHB reduces grain yield (YLD) and test weight (TW; weight per unit volume), and causes Fusarium damaged kernel (FDK) and deoxynivalenol (DON) mycotoxin contamination of grain. Data were collected from several field experiments conducted in Ohio to i) model FHB/YLD and FHB/TW relationships as influenced by cultivar and the severity of Stagonospora nodorum leaf blotch (SLB, another disease of economic importance in Ohio); ii) develop integrated management programs to minimize losses caused by FHB, and iii) conduct economic analyses of FHB management programs. Depending on the objective of the study, plots of FHB susceptible and moderately resistant cultivars were planted and inoculated with different spore concentrations of F. graminearum and S. nodorum to generate a range of FHB and SLB intensities and corresponding YLD and TW values, treated with a fungicide, and harvested with different combine harvester settings. Linear mixed model variance and covariance analyses and random-effects meta-analyses were used to quantify FHB index (IND)/YLD and IND/TW relationships, and to determine the effects of cultivar, fungicide, and grain harvesting strategy (modification to combine settings to remove small and lightweight kernel) on IND, FDK, DON, YLD, and TW. The final models for both relationships were of the form y=a+b(IND). YLD and TW decreased as IND increased, with the rates of reduction ranging from -54 to -46 kg ha-1 %-1 for YLD and -3.2 to -2.3 kg m-3 %-1 for TW. Neither cultivar nor SLB affected the IND/YLD relationship, but SLB affected the height of the IND/TW regression lines, and cultivar affected the rate of TW reduction per unit increase in IND. The level of IND at which a 1 MT ha-1 yield loss was predicted to occur ranged from 19 to 22%, whereas a 100 kg m-3 reduction in TW was predicted to occur between 31 and 44% IND. Several FHB management programs were developed. The greatest percent reduction in FDK (25 to 62%) and DON (33 to 52%) and increase in YLD (18 to 26%), relative to the reference program (without any management intervention), was observed for programs that included moderate resistance and fungicide treatment. The greatest percent increase in TW (8 to 10%) relative to the reference was observed when modified combine setting was integrated with resistance and/or fungicide. Overall, the most effective management programs all included fungicide treatment, two included moderate resistance, and two modified combine setting. Relative to the reference, these programs resulted in 30 to 51% reduction in total estimated price discount, $127 to 312 ha-1 increase in gross cash income, and economic benefits ranging from $31 to 272 ha-1, depending on the level of IND (5 to 15%), grain price ($118 to 276 MT-1), and fungicide application cost ($40 to 96 ha-1). Results from these studies will be used in more general models to evaluate the economics of FHB/DON management strategies.

This book was released on 2011-08 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2010 in the subject Biology - Botany, grade: none, University of Minnesota - Twin Cities, language: English, abstract: Fusarium head blight caused by Fusarium graminearum Schwabe is an economically important disease as it results in yield and quality losses of infected grain and the accumulation of mycotoxins produced by the invading fungus. Though it is well established that moisture around the anthesis period promotes FHB development and trichothecene accumulation, the role of moisture from anthesis to harvest has been largely overlooked. The objective of this study was to examine the influence of environmental factors, especially moisture, host resistance, and pathogen variation on infection, FHB disease development and mycotoxin production and accumulation in planta. The split-split-plot Field experiments were conducted in 2006-2008. Main plots were the duration of mist-irrigation after inoculation. Three wheat cultivars used as sub-plots were Alsen, 2375 and Wheaton. Sub-sub-plots were F. graminearum isolates. Plots were inoculated twice, at anthesis. FHB severity was assessed 21 dai. Visually scabby kernels, deoxynivalenol, 15-acetyldeoxynivalenol, 3-acetyldeoxynivalenol and nivalenol were determined on grain harvested at maturity. Additionally, in 2007 and 2008, whole heads were sampled at 0, 7, 11, 14, 21, 28 and 41 dai analyzed for mycotoxins. Severity, VSK and the DON concentration of mature grain, were significantly higher in the susceptible wheat cultivar Wheaton than in the other two cultivars examined. Although FHB severities were not significantly different in plots receiving different durations of mist irrigation, VSK were significantly lower in the treatments receiving the least amount of mist-irrigation than for treatments receiving mist-irrigation for longer periods, suggesting that extended periods of moisture promote disease development. DON was however significantly lower in the longest misting trea

Available in PDF, EPUB and Kindle. Book excerpt: For the first time in over 20 years, a comprehensive collection of photographs and descriptions of species in the fungal genus Fusarium is available. This laboratory manual provides an overview of the biology of Fusarium and the techniques involved in the isolation, identification and characterization of individual species and the populations in which they occur. It is the first time that genetic, morphological and molecular approaches have been incorporated into a volume devoted to Fusarium identification. The authors include descriptions of species, both new and old, and provide protocols for genetic, morphological and molecular identification techniques. The Fusarium Laboratory Manual also includes some of the evolutionary biology and population genetics thinking that has begun to inform the understanding of agriculturally important fungal pathogens. In addition to practical “how-to” protocols it also provides guidance in formulating questions and obtaining answers about this very important group of fungi. The need for as many different techniques as possible to be used in the identification and characterization process has never been greater. These approaches have applications to fungi other than those in the genus Fusarium. This volume presents an introduction to the genus Fusarium, the toxins these fungi produce and the diseases they can cause. "The Fusarium Laboratory Manual is a milestone in the study of the genus Fusarium and will help bridge the gap between morphological and phylogenetic taxonomy. It will be used by everybody dealing with Fusarium in the Third Millenium." --W.F.O. Marasas, Medical Research Council, South Africa

Available in PDF, EPUB and Kindle. Book excerpt: There is an urgent need to expand our knowledge of both the nature of the toxigenic fungi that are widespread on economically-important plants and the effect of their toxic secondary metabolites on human health. Informa tion about the production of mycotoxins by plant pathogens, particularly by species of Fusarium, Aspergillus and Penicillium, their occurrence in infected plants, as well as their role in the plant-pathogen interaction, for example as virulence/pathogenicity factors, is a pre-requisite for preventing plant disease and hence for reducing the Ievels of mycotoxin contamination. Fusarium infections in cereals and other crops are a particular problern world-wide and recent epidemics on wheat in Europe, the USA and Canada have again focused attention on this problem. Fur thermore, species ofAspergillus and Penicillium and their related mycotoxins, particularly Ochratoxin A, represent another consistent problern on cereals and grapes, especially in Europe where 40% of the global grape crop is grown. The aim of this publication is to gather together specialist updated reviews based on papers originally presented during a Workshop of EU Cost Action 835 entitled 'Agriculturally Important Taxigenie Fungi', held in Rome, 7-8 October 1999 at the Plant Pathology Research Institute. We hope the diversity of the contents will stimulate discussion, encourage the sharing of information and result in cross-fertilization of ideas needed for the solution of the present problems. This special issue will be of particular value to interdisciplinary scientists and especially mycologists, mycotoxicologists, plant pathologists and those concerned about the quality of food and food products.
