Fusarium Diseases of Canadian Grain Crops: Impact and Disease Management Strategies

摘要: The genus Fusarium, first described in the early nineteenth century, is composed of a wide range soil-borne saprophytic and pathogenic fungi. More than few hundred different phylogenetic species Fusarium have been identified to date. Plant are main target pathogenicity, although some species, including F. chlamydosporum, oxysporum verticillioides, shown infect immune-compromised humans. It said that most plant susceptible at least one disease caused by can cause vascular wilt diseases, for which broad host plants susceptible, involving fungal colonization xylem via roots growing mycelium eventually causes vessel obstruction, blocking transport water aerial parts plant. In dicots, over 100 formae speciales as causative agents wilt, ff. spp. lycopersici, phaseoli pisi, tomato, beans pea crops, respectively. also root rots stem various field crops worldwide, peas related pulse crops. cereals corn (maize) crown rot (FCR) stalk (stem) rot, respectively, group pathogens from those responsible diseases include graminearum, culmorum, avenaceum, verticillioides pseudograminearum. addition inflorescence structures, causing head blight (FHB; known scab) ear (sometimes referred FEB) maize, leads damage yield loss developing kernels. There an overlap with blights. Many these produce harmful mycotoxins, trichothecenes fumonisins, accumulate kernels infected heads. this chapter, we will start introduction their classification genetics, provide review three groups Canadian (cereals, maize pulses), followed sections on management strategies, toxin quantification methods.
