Use pre-seed burnoff and pre-harvest herbicide for cleavers control

Science Edition: Integrated Pest Management
Science Edition 2019—KEY RESULT: Cleavers can germinate very early in the spring, making pre-seed burnoff a good way to control the weeds when they’re small and limit cleavers seed in harvested canola. Pre-harvest saflufenacil plus glyphosate may also provide short- and long-term management. PROJECT TITLE, PRINCIPAL INVESTIGATOR:  “Assessing the influence of base germination temperature and chemical desiccants...

Understand the limitations of combine grain-loss monitors

Science Edition 2019—You can’t manage what you can’t measure. That adage from the business world also applies to harvest grain losses. While current grain loss monitors have been slowly improving over time, they still do not directly correlate actual grain loss to the grain loss signal. As a result, grain loss monitors do not provide operators with...

Root ‘electricity’ measurement will help breed more resilient canola

Science Edition - Completed Projects
Science Edition 2019—Roots function as an early warning system for Brassica crops, detecting and responding to environmental stresses. Understanding root biology will help scientists and farmers create sturdier, stress-resistant crops. But root systems are complex, and difficult to study in a non-destructive manner. Bao-Luo Ma’s team investigated the feasibility of measuring electrical properties of roots to investigate...

Multiple genes and crop rotation enhance the durability of clubroot resistance

Science Edition: Genetics
Science Edition 2019—Cultivar resistance is the key to managing clubroot, which continues to spread on the Canadian prairies. Recently in Alberta, 17 “new” pathogen pathotypes were identified and all appeared virulent to previous resistant cultivars in the marketplace. This erosion of single-gene resistance is also being reported across western Canada, including a new variant of pathotype 3A...
