Book Description
The book provides a comprehensive record of current knowledge on the nature of Fusarium head blight, the damage it causes, and current research on how to control it. The book begins with a historical account of Fusarium head blight epidemics that gives context to recent attempts to control epidemics in wheat and barley. A review of pathogen taxonomy and population biology helps scientists to see relationships among head blight pathogens and other Fusarium species. The information on epidemiology included in this review also provides an understanding of the weather conditions and cultural practices that promote explosive epidemics. New information on infection processes will lead the reader to a better understanding of how to breed for resistance in wheat and barley.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
Fusarium head blight (FHB), caused by several Fusarium species-mainly Fusarium graminearum, F. culmorum, and F. avenaceum-is a devastating disease of wheat which reduces both grain yield and quality. FHB affects the grain protein content by destroying starch granules, storage proteins, and cell walls and consequently decreases the quality of dough properties. It is also associated with mycotoxin contamination and is a significant threat to animal and human health. Furthermore, Fusarium spp. affect plant development and trigger different morphological, physiological, biochemical, and molecular changes. Current climate change scenarios predict an increase in the number of epidemics caused by this disease, and many different strategies for disease control are currently being researched. This Special Issue aims to detail the latest achievements regarding Fusarium disease in wheat, including the genetics or physiology of resistance, resistance mechanisms, host-pathogen interactions, and agronomic approaches in the field (fungicidal management, the integration of host resistance and fungicides, and the timing of fungicide application). Original research, reviews, and opinions on recent advances in strategies for the control of Fusarium disease in wheat were also welcome.
