Canola Crops

[sewen]

Lots of Sclerotinia starting to show up in fields around North East Alberta.

Crops may not be as good as they once looked.

What are others seeing for crop diseases? What is yield potential now? How long to harvest? Let us know your region.

I am in south central Manitoba.

There is lots of canola around here, more than usual. It seems to be evenly split in three seeding time groupings, with a third before the snow of May 11, a third near the end of May (when it was still too wet to properly seed), and the last third in the third week of June.

The early stuff is showing a fair bit of sclerotinia, with my estimate of loss in yield of 10 to 12%. I dont know yet about the later canola.

None the less, all of the canola crop looks great, with a high yield potential in spite of some disease pressure, although the later stuff looks doubtful to escape frost damage, as it is now at 40 to 50% bloom. Average yields of 40 or more bu per acre would not surprise me, with some expected in the 50's.

I have seen fields sprayed and not sprayed in NE sask, and untreated canola has high to very high sclerotinia infection rates. Seeds are still watery and 1 in three plants are infected. In the sprayed fields it is more like 1 in twenty. I think untreated fields are going to be hard to swath and fairly disappointing.
