“…(Loskutov, Rines, 2011). Особое значение приобрело заболевание, связанное с грибами Fusarium, фузариоз зерна, которое значительно уменьшает получаемый урожай и, кроме того, за счет способности некоторых видов фузариевых грибов образо-вывать микотоксины снижает качество получаемого зерна (Tekauz et al, 2004;Гагкаева, Гаврилова, 2011;Гагкаева и др., 2011;Martinelli et al, 2014).…”

“…Fusarium head blight infection of oat has also been assessed using the frozen blotter method (Limonard 1966). The sporadic and localized presence of FHB in oat has been reported from Quebec, Prince Edward Island, New Brunswick, Nova Scotia and Ontario (Tekauz et al 2004;). Significant differences have been found in the level of Fusarium infection in oat cultivars in eastern Canada (Couture 1982), and Norway (Bjornstad and Skinnes 2008).…”

“…Six species in the Fusarium genus were the most frequently recovered from seed corn stalks in Ontario during 1998Á2000 (Tamburic-Ilincic and Schaafsma 2009 TamburicIlincic and Schaafsma 2006). Fusarium head blight is a major disease of oat in western Canada (Tekauz et al 2004). Several of the Fusarium species infecting oat can produce mycotoxins.…”

“…Visual scoring for FHB symptoms in oat is more challenging than in other cereals. Tekauz et al (2004) reported that FHB can be underestimated in oat when based only on visual symptoms in the field and they recommended DON testing and evaluating level of Fusarium infected kernels in the lab. Fusarium head blight infection of oat has also been assessed using the frozen blotter method (Limonard 1966).…”

Tamburic-Ilincic, L. 2010. Fusarium species and mycotoxins associated with oat in southwestern Ontario, Canada. Can. J. Plant Sci. 90: 211Á216. Fusarium graminearum Schwabe [teleomorph: Gibberella zeae Schwein. Petch] is the predominant Fusarium species pathogenic to wheat, barley and corn in Ontario and produces the mycotoxin deoxynivalenol (DON) in grain. The first objective of this study was to determine the Fusarium spp. and mycotoxin concentrations (DON, HT-2, and T-2) from commercial oat (Avena sativa L.) fields grown in the same area as wheat, corn and barley in Ontario. The second objective was to measure DON level across cultivars grown in the Ontario Performance Trial (OPT) after sprayinoculation with F. graminearum. Fusarium sporotrichioides, F. graminearum and F. poae were the predominant species identified in oat.

Discoloration of subcrown internodes (SIs) and crowns/lower culms (CLCs) of 87 oat crops across Saskatchewan in 1998-1999 and of SIs in 31 oat crops in eastern Saskatchewan (Black Soil Zone) in 2000-2001 was evaluated. Fungi in discolored tissue were isolated, identified and quantified, and the percentage of fields from which each fungus was isolated at least once (occurrence) and their relative percentage isolation levels were determined. In the 1998-1999 survey, discoloration severity varied more between years than among soil zones. Fusarium was the most common genus present, and F. culmorum the most common species. This was followed by F. equiseti, Microdochium bolleyi, Cochliobolus sativus, and F. avenaceum. Levels of C. sativus were lower in oat than those reported for wheat and barley in parallel province-wide surveys. Percentage isolation of F. culmorum was higher in the Brown than in the Black/Dark Gray Soil Zone, whereas the percentage occurrence of F. avenaceum was highest in the Black/Dark Gray Soil Zone. In 2000-2001, in eastern Saskatchewan, M. bolleyi, F. avenaceum, C. sativus, F. equiseti, Alternaria spp., and Pyrenophora avenae were the most common fungi isolated from discolored oat SIs. Similar to reports from wheat and barley, F. graminearum was isolated from SIs in eastern Saskatchewan at low levels. For the most part, neither previous crop nor tillage system affected fungal levels in SIs. P. avenae levels increased when the previous crop was another oat rather than wheat or barley. We conclude that oat could maintain or increase inoculum levels of Fusarium pathogens that cause damage to cereal crops in Saskatchewan. This is supported by results from a crop residue study in eastern Saskatchewan that showed that F. avenaceum, F. culmorum and F. graminearum occurred at similar or higher levels in oat fields than in fields of wheat or barley. Key words: Oat, root rot, crown rot, crop rotation, tillage system, Fusarium head blight, Fusarium spp., Fusarium avenaceum, Fusarium culmorum, Fusarium graminearum, Cochliobolus sativus, Pyrenophora avenae
