Swathing after frost. After heavy frost, swathing may be necessary to preserve yield. After light frost, leave the crop standing but check again after a couple days to make sure damage isn’t worse than expected.
Green scheme. Early swathing, especially in hot fast-curing conditions, can lock in high green counts. Wait until 60% seed colour change on the main stem if you can. Swath at night if necessary.
Clublegtinia. No, we have not found a combo disease of clubroot, blackleg and sclerotinia stem rot, but all three can be found in canola fields this harvest. Now is a good time to assess your 2014 disease situation.
They’re baaaack! Flea beetles are hopping around canola pods. They won’t be doing much damage — certainly not economic levels — but they make growers twitchy just the same.
