Speed one factor in lower harvest losses

Brent Lensen offered two canola fields for a study measuring canola harvest loss. His losses were lower than study’s average – possibly due to his 3-mph combine ground speed.

Identification of superior crop rotations

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...

Aster yellows: Seed treatment benefit; rating damage

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...

High rates of parasitism on diamondback moth larvae

Key result: This study continued work initiated by earlier research which showed that parasitism of diamondback moth larvae and pupae can be relatively high early in the season. Canola producers are encouraged to carefully monitor populations, waiting a few days after nominal thresholds are reached to provide beneficial insects an opportunity to control larvae and...

Storage bags work best with dry canola

Key result: This research looked at the feasibility of bag storage for canola and the effects on seed quality based on moisture content and length of storage time. Dry canola seeds can be safely stored for six to eight months in bags, but canola at 12 per cent moisture should be stored only temporarily. Project...
