Canola School: Tallying Up the Risk Factors for Sclerotinia Pressure


Sclerotinia-check-list1There are few things as lovely on the Canadian Prairies as a blooming field of canola (flax comes to mind, but who wants to deal with the resulting residue? Egads.) Yes, canola’s yellow flowers sure are pretty, but did you know they’re also food? For the sclerotinia pathogen, that is.

That means that as the canola crop comes into flower, it’s time to assess the threat of sclerotinia to the crop. Sclerotinia can cause significant yield loss, especially if the lower parts of the stem are damaged by the disease.

In this Canola School episode, Shawn Senko, Saskatoon-area agronomist with the Canola Council of Canada, tallys up the risk factors that go in to assessing whether or not to spray a fungicide, how to estimate percent bloom, and how farmers with variable fields may save on fungicide costs.

He also refers to the use of the sclerotinia risk checklist, seen at right (click for a larger image), and the apothecia germination depots: click here for the sclerotinia apothecia germination map!
