Key result: This study revealed new information about yield losses from aster yellows, tentative economic thresholds for leafhoppers, and the lifecycle patterns and host preference of swede midge. Growers should scout crops for swede midge and leafhoppers and consult with agronomists if either pest or aster yellows are identified. Project title, Principal investigator: “Aster yellows...

Key Result: The southeast Peace region has the highest intensity of canola acres and short canola rotations in the western Canadian Prairies. However, this study suggests that this may not be the best choice for growers in terms of long term yield, cropping system sustainability, soil moisture use, root health and economics. Project Title, Principal...

Key result: The study found that seed treatment can reduce leafhopper feeding and therefore suppress aster yellows (AY). It also produced a five-point rating scale to score canola plants for AY damage and help predict yield loss. Project title, Principal investigators: “Seed treatments as an alternative method of controlling leafhoppers and aster yellows disease in...
