What better way to learn about blackleg?
Manitoba canola grower Andre Badiou took part in a study to find out more about the blackleg on his farm and pick up a few management tips. He helped with the study, and the study helped him.

Lots of diversity in clubroot resistance
Key result: Clubroot resistance in Canadian canola varieties relies almost entirely on one source, “Mendel”. This study identified many other genes, found genetic markers for them and then crossed some of them into B. napus lines that could be used for breeding. Canola seed breeders can use the results of this work to broaden and...

New threats: Aster yellows and swede midge
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...

One step closer to sclerotinia control
Key result: Sclerotinia stem rot-tolerant varieties are available and efforts continue to improve varietal resistance, in both the public and private sectors. Researchers on this project have identified previously undiscovered genes associated with the plant defense response, providing valuable resources for researchers interested in developing sclerotinia-resistant canola lines. Project title, Principal investigators: “Getting one step...

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...
