P. 2014。减少加拿大草原硬粒小麦斑叶病和穗镰孢菌感染的农艺措施。可以。[j] .植物科学，2004(4):444 - 444。赤霉病（Fusarium head blight， FHB）已成为硬粒小麦的重要病害。硬质(Desf)。在湿润和半湿润的草原地区，伴随着叶子斑点，黑点和红色污迹。它们共同导致粮食产量和粮食质量下降。研究了播种量、施氮量、杀菌剂处理和品种对硬粒病害严重程度、作物发育、籽粒产量和品质的影响。采用四因子设计，采用两种播种率（150和300活籽m - 2）、两种施氮率（75%和100%推荐施氮率）、3个品种（AC Avonlea、AC Morse和AC Navigator）、4种杀菌剂处理（不施用、旗叶施用丙环唑、花期施用戊康唑、f - 1施用丙环唑）。

Plant Sci. 94: 141–152. Fusarium head blight (FHB) has become an important disease of durum wheat [Triticum turgidum L. ssp. durum (Desf.) Husn] in the humid and sub-humid regions of the prairies along with leaf spots, black point and red smudge. Together, they contribute to lower grain yields and grain quality. The study objective was to determine the effect of seeding rate, nitrogen (N) fertilizer rate, fungicidal treatment, and cultivar on disease severity, crop development, grain yield and quality in durum. A four-way factorial design was used with two seeding rates (150 and 300 viable seeds m−2), two N rates (75 and 100% of recommended rate), three cultivars (AC Avonlea, AC Morse and AC Navigator), four fungicide treatments (no application, propiconazole at flag leaf, tebuconazole at anthesis, and propiconazole at f...
