Biology and integrated management of wheat stem sawfly, cephus cinctus norton (hymenoptera: cephidae), with a discussion of needs for future researchDownload
The wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is historically one of the most important economic insect pests in the northern Great Plains of North America. Within this geographical region, the areas subjected to greatest attack are southern Alberta and Saskatchewan,...
Competitive traits and the stability of wheat cultivars in differing natural weed environments on the northern Canadian prairiesDownload
Nine spring wheat cultivars, selected on the basis of height, tillering capacity and maturity, were grown in differing levels of natural weed presence at three locations in Edmonton and New Norway, Alberta between 2003 and 2004. The objectives of the study were to (1) identify competitive traits...
Performance and stability of performance of spring wheat variety mixtures in organic and conventional management systems in western CanadaDownload
Wheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining and stabilizing yield for both organic and conventional producers. The present study examined the responses of three Canadian western red spring wheat varieties in sole crop and in variety...
