“…The latter observation agrees with a report on winter wheat by Sturz and Bernier (1989) that a rotation with flax or canola reduced levels of F. culmorum compared with continuous wheat. These findings do not agree with those of Hall and Sutton (1998) who reported that isolation of F. culmorum and F. graminearum from winter wheat crowns was not correlated with crop rotation. However, these pathogens occurred at low levels in both their and our studies.…”

“…in the roots and crowns of durum and spring wheat sampled throughout Saskatchewan (Fernandez and Jefferson 2004), and in SI of spring wheat sampled from a long-term crop rotation study in southwestern Saskatchewan . In the mid1980s, F. avenaceum was also isolated from lesioned SI of spring wheat sampled in Minnesota (Windels and Wiersma 1992), and was the most common species isolated from winter wheat crowns in southern Ontario (Hall and Sutton 1998). In greenhouse trials, F. avenaceum caused as much disease in winter wheat as F. culmorum or F. pseudograminearum O'Donnell & T. Aoki (Smiley et al 2005).…”

. 2007. Response of common root rot in wheat to crop management in eastern Saskatchewan. Can. J. Plant Sci. 87: 953-963. A survey of common root rot in spring wheat (Triticum aestivum L.) and durum wheat (T. turgidum L. var. durum) crops was conducted in eastern Saskatchewan from 1999 to 2001 to investigate the association of agronomic practices with disease and fungal populations, in particular Fusarium species associated with Fusarium head blight (FHB), which is a disease of increasing importance in this region. Spring wheat preceded by summerfallow, or grown after a sequence that included summerfallow and a cereal crop, had increased levels of Cochliobolus sativus and lower levels of most Fusarium spp. in discoloured subcrown internodes. Cropping sequences that included at least one noncereal crop in the previous 2 yr resulted in higher percentage isolations of F. avenaceum and F. graminearum than sequences which did not include noncereal crops. Highest levels of F. avenaceum, the most common FHB pathogen in the province, were observed when the previous crop was a pulse. Tillage system effects depended on the previous crop. When wheat was preceded by an oilseed crop, C. sativus decreased as the number of tillage operations decreased, whereas F. avenaceum and Microdochium bolleyi increased with a reduction in tillage. Associations of fungal isolations with previous glyphosate use were negative for C. sativus and positive for F. avenaceum and M. bolleyi, although these effects varied depending on tillage system. Increased levels of important Fusarium pathogens were thus associated with current trends in production practices, namely continuously cropped diversified rotations and less reliance on mechanical soil tillage. Further investigation into the relative role of tillage intensity and glyphosate use versus cropping sequence on Fusarium populations in underground wheat tissue is needed. L'objectif était d'établir les liens existant entre les pratiques agricoles et la maladie ainsi que les populations de cryptogames, principalement les espèces du genre Fusarium associées à la brûlure de l'épi (BEF), maladie dont l'importance ne cesse de grandir dans cette région. La population de Cochliobolus sativus est plus élevée et celle de la majorité des espèces de Fusarium est plus faible dans les entrenoeuds situés sous le collet quand le blé de printemps est cultivé sur jachère estivale ou après un assolement incluant une culture céréalière et une jachère. On a isolé un plus grand nombre de F. avenaceum et de F. graminearum dans les assolements qui comprenaient au moins une autre culture que des céréales au cours des deux années antérieures que dans ceux n'incluant que des céréales. La plus forte concentration de F. avenaceum, microorganisme le plus souvent responsable de la BEF dans la province, a été relevée après culture d'une légumineuse. L'incidence des méthodes de travail du sol dépend de la culture antérieure. Quand un oléagineux précède la culture du blé, la population de C. sativus diminue avec le nombre d'op...

“…Warmer winters and moist springs, which favour infection and colonization by R. cerealis, usually increase incidence and severity of disease (Clarkson and Cook 1983;Wiese 1987;Polley and Thomas 1991;Colbach et al 1997;Cromey et al 2002). Regional differences in incidence of sharp eyespot, which occurs most often in cooler regions, were also reported from the United Kingdom (Polley and Thomas 1991) and Canada (Hall and Sutton 1998).…”

Sharp eyespot caused by Rhizoctonia cerealis was assessed in four winter wheat crops surveyed at four locations in north-central Poland in [2006][2007][2008][2009]. At the four locations symptoms developed on 41.9-67.7 % of shoots of all plants (average of 4 years) and on 49-73.5 % of shoots of diseased plants (average of 4 years). Slight (category 1) disease was most frequent, occurring on 24.4-41.3 % of shoots (range 14.8-51.3 %); moderate (category 2) disease was less frequent, occurring on 16.9-25.5 % of shoots (range 8.9-32.4 %); severe (category 3) disease was least frequent, occurring on 3.2-7.1 % (range 0-22.0 %) of shoots. Sharp eyespot affected wheat growth and yield, and grain quality. Disease, especially in the severe category, was associated with significant decreases in plant and ear dry weights, number of grains per ear, grain dry weight per ear and thousand-grain weight, and with increases in grain protein and wet gluten contents, Hagberg falling number and sedimentation value. There was an association between occurrence of sharp eyespot in stems and colonization of grain by fungi. Alternaria alternata and E. nigrum were the most common species.

“…Fusarium equiseti (Corda) Sacc. sensu Gordon is a cosmopolitan species that colonizes senescing plants and also parasitically infects wheat (Hall and Sutton 1998). These species cause disease that can be broadly classified as cortical rot, and can also be named foot, root, crown, stem, and dry rots.…”

Influence of Fusarium and Wheat Stem Sawfly Infestation on Volatile Compounds Production by Wheat Plants

Plants that were infested by the wheat stem sawfly emitted significantly increased amounts of the secondary metabolites linalool, linalool oxide, ß-farnesene, ß-caryophyllene, and 4-heptanone in comparison to uninfested plants. Wheat plants parasitized by Fusarium species also have emitted volatiles. The amount of volatiles released varied by infective species of Fusarium and volatile patterns varied over time for both sawfly infestation and pathogen infection. Plants that were stressed by both herbivory and pathogens emitted even greater amounts of certain volatiles. Surprisingly, larval sawfly mortality was much greater in plants infected by Fusarium species, and both mortality and the rate of volatile release varied by Fusarium. The role of these plant volatiles are further discussed in the context of defensive plant responses to Fusarium and sawfly infestation.
