Using clubroot resistant genetics and lengthening rotations are highly recommended practices for managing clubroot on the Prairies. But is there more farmers could do? “Ninety per cent of those clubroot spores can die with a two-year break, so one in three rotation, that’s really critical, if you have a shorter rotation than that, and you’re… Read More

Lygus bugs attack several broadleaf crops, including alfalfa, flax, faba beans, lentils, and canola. They are a pest of concern that have been a focus for Hector Carcamo, research scientist at Agriculture and Agri-Food Canada, Lethbridge, Alta. He joins Kara Oosterhuis for this Canola School episode to talk about lygus bug species, the conditions they… Read More
It’s been dry, windy, and hot across most of the Prairies this year, and an insect pest that you don’t typically see attacking canola is thriving in these conditions. Lyle Jensen, agronomist at AgroPlus, joins Kara Oosterhuis for this Canola School episode where they discuss grasshopper pressures and options for control. “As we’ve basically been… Read More
Cabbage seedpod weevil can cause considerable yield loss to a canola and other brassica crops, such as mustard. As adults, the pest is three to four millimetres in length, is ash-grey in colour, and has a prominent curved snout, similar to other weevils. Meghan Vankosky, field crop entomologist at Agriculture and Agri-Food Canada Saskatoon, joins… Read More
It’s been dry in parts of Western Canada heading into canola flowering, but has it been dry enough to hold off on spraying for sclerotinia? That’s a question many growers and agronomists in drought-affected areas have been asking themselves over the last week or two. There are really two basic factors to consider in the… Read More
It’s well-known that canola does not like heat during flowering. As soon as daytime highs rise beyond 30 degrees C — as we’re seeing through the current heat wave in Western Canada — the plant can become heat stressed, which leads to blasting and aborted pods. High temperatures can essentially cause a breakdown in communication… Read More
Herbicide strategy for in-crop applications in canola first requires knowing what weeds are out there, and keeping in mind that two applications is an option. In this Canola School episode, Jaeda Hoppe, field crop agronomist with UYMI Agronomy at Biggar, Sask., says that two in-crop herbicide applications is likely if the weeds are there and… Read More
Winter canola isn’t actually that new of a crop to Ontario — there were certainly some acres produced in the 80s and 90s — but there’s been a resurgence in the last five years with increased availability of a new variety. Meghan Moran, OMAFRA canola and dry edible bean specialist, joins Bernard Tobin in a… Read More
Flea beetles are one of the most detrimental insects for the early stages of canola, but new research sheds some light on how seeding date can be used to get ahead of this pest. In this Canola School episode, Hector Carcamo, research scientist at AAFC Lethbridge, shares some interesting results on how two species of… Read More
The Canola Council of Canada (CCC) has recently updated a few agronomy graphics, including the life cycle of blackleg. “We’ve had different life cycles in the past, but we wanted to update it and provide a little bit more information kind of in a one shot,” says Justine Cornelsen, agronomy specialist with CCC. In this… Read More
