Abstract Canada is one of the largest wheat producers in world, and grown over an area spanning most southern latitudes, with prairie region (provinces Saskatchewan, Alberta, Manitoba) being main producer. Several pathogens pests attack wheat, but at present fusarium head blight (FHB), stripe rust, leaf spots are damaging diseases to production Canada. Historically, smuts, stem rust caused major crop losses can still pose serious threat if management practices relaxed. Cropping used by...
Wheat occupies a special role in global food security since, addition to providing 20% of our carbohydrates and protein, almost 25% the production is traded internationally. The importance wheat for was recognised by Chief Agricultural Scientists G20 group countries when they endorsed establishment Initiative 2011. tasked with supporting research community facilitating collaboration, information resource sharing helping build capacity address challenges facing an increasingly variable...
Abstract The wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is historically one of the most important economic insect pests in northern Great Plains North America. Within this geographical region, areas subjected to greatest attack are southern Alberta and Saskatchewan, southwestern Manitoba, eastern Montana, Dakota, South western Minnesota. Cumulative grain-yield losses annual associated with pest can exceed 30% $350 million, respectively. Solid-stemmed cultivars common...
The inclusion of winter cereals in spring-annual rotations the northern Great Plains may reduce weed populations and herbicide requirements. A broad range spring were compared for ability to suppress weeds maximize grain yield at Lacombe (2002 2005) Lethbridge (2003 2005), Alberta, Canada. High seeding rates (≥ 400 seeds/m 2 ) used all years crop competitive ability. Spring achieved high crop-plant densities (> 250 plants/m most sites, but had lower plant due winterkill, particularly...
Wheat production is required to supply food for the world's population, and increases in will be necessary feed expanding population. Estimates show that must increase by 1 billion metric tons meet this demand. One method future demand wheat yields reducing gap between actual potential yields. Potential represent an optimum set of conditions, a more realistic would compare with attainable yields, where these years record there no obvious limitation. This study was conducted evaluate yield...

Winter wheat production in Canada is approximately 5% of all the seeded Canada; however, it has important economic and agronomic benefits for growers. Stripe rust wheat, caused by Puccinia striiformis f. sp. tritici Eriks. occurs across western many years; as a result, prudent to evaluate strategies control stripe winter wheat. The objective this project was effects fall spring fungicide application (metconazole pyraclostrobin) on rust, well leaf spot severity, impact yield quality (Triticum...
Abstract Growers in the Northern Great Plains (NGP) are increasingly adopting winter wheat (WW; Triticum aestivum L.) into their crop rotations years of ideal fall planting conditions due to its high yield potential. Our study evaluated WW responses rotational crops, soybean ( Glycine max and lentil Lens culinaris L.), field peas Pisum sativum faba bean Vicia canola Brassica napus flax Linum usitatissimum oats Avena sativa different schemes following crop: WW‐WW, hard red spring (HRSW)‐WW,...
The wheat stem sawfly (WSS; Cephus cinctus Norton (Hymenoptera: Cephidae)) is a serious pest of (Triticum aestivum L.) in the Great Plains North America. Two species parasitoids, Bracon cephi Gahan and B. lissogaster Muesebeck, effectively attack C. cinctus; therefore, agronomic practices must strive to conserve these endemic parasitoids. Our objectives were 1) establish distribution within host infestation patterns 2) study parasitoid responses genetics, stubble height straw management at...
A resurgence of the wheat stem sawfly, historically most important pest in northern Great Plains, has been observed western Canada over past decade. Host plant resistance form solid-stemmed cultivars remains primary management strategy for this pest. The objectives study were to determine effects cultivar on sawfly fitness and sex ratio. studied varied with respect diameter pith expression included representatives red seed, spring hollow-stemmed common durum classes. We present results from...

Yield stability analysis of broadly adaptive triticale germplasm in southern central Alberta, Canada for industrial end-use suitability. Can. J. Plant Sci. 91: 125–135. Triticale (×Triticosecale Wittmack) is a cereal crop with high grain yield biomass potential, which are traits desired biorefinery processes that currently utilize wheat (Triticum aestivum). This study was conducted to evaluate the performance...
The wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), has reached outbreak status at most locations in the southern Canadian prairies. Solid-stemmed wheat, Triticum aestivum L., cultivars, which are less susceptible to damage, remain primary management option. This article quantifies effect of sawfly damage on grain yield and quality harvest determines how cultivar selection affects losses. cultivars were compared with hollow-stemmed blends a 1:1 ratio each. exception...
Poor stand establishment resulting in lower yield is a major constraint to expanding winter wheat ( Triticum aestivum L.) across western Canada. To address this issue, we conducted study totaling 26 site‐years over three growing seasons (2011–2013) observe crop responses system manipulations involving seeding rate (200 and 400 seeds m −2 ), seed size as proxy for plant vigor (light/thin, moderate, heavy/plump), dual fungicide/insecticide treatment, on establishment, yield, quality. Fall...
Fusarium head blight (FHB) is a devastating disease of wheat because direct detrimental effects on grain yield, quality, and marketability production mycotoxins (e.g. deoxynivalenol or DON). Conditions most favourable for the development FHB are high humidity, frequent rainfall relatively warm night temperatures at heading, especially in regions where host crop residues present. These risk factors have resulted significant westward expansion Canadian prairies, while favouring continued...
Advances in cultivar development and the demand for winter wheat ( Triticum aestivum L.) as an ethanol feedstock has increased acreage across Canadian Prairies. A sustainable production package is required to maintain this renewed interest. Experiments were established 2002–2004 at Lethbridge Lacombe, AB, determine cultivar, seeding rate, herbicide effects on weed competition crop yield. Treatments included a factorial combination of four contrasting cultivars (Radiant, CDC Osprey, Falcon,...
The wheat stem sawfly [ Cephus cinctus Norton (Hymenoptera: Cephidae)] (WSS) has been a serious pest of ( Triticum aestivum L.) since the late 19th century. Adoption solid‐stemmed cultivars, which are available only in spring bread class Canada, can mitigate damage but trait that confers resistance tends to be variable. Five other classes grown within geographical range C. and vulnerable WSS infestation, entire production area for durum T. turgidum western Montana, North Dakota lies...
Wheat, Triticum aestivum L., producers are often reluctant to use solid-stemmed wheat cultivars resistant stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), due concerns regarding yield, efficacy or market opportunities. We evaluated the impact of several planting strategies on yield and quality sawfly infestation at two locations over a three-year period.
