There’s no doubt the 2021 drought across the Prairies had widespread negative impacts. Heading into the 2022 season there was a lot of concern for herbicide carryover, but as Warren Ward, agronomy specialist with the Canola Council of Canada explains, there is some positive carryover to keep in mind: nitrogen carryover. Across Saskatchewan especially, there… Read More

Diamondback moths blow in at some point early in the season (thanks, America!), and set about living on the Prairies and in the canola crop for the rest of the growing season. Jordan Bannerman, entomologist with the University of Manitoba, says that understanding when the moths arrive, through the use of pheromone traps, and how long… Read More
By early July, many canola fields across the Prairies are in the beginning stages of bolting. According to Héctor Cárcamo, research scientist with Agriculture and Agri-Food Canada at Lethbridge, Alta., that’s a great time to start thinking about the cabbage seed pod weevil. Before worrying about thresholds and spray timing for the insect pest that can… Read More
The decision whether to spray a fungicide for sclerotinia stem rot always comes back to the disease triangle — a susceptible host, the presence of the pathogen, and a favourable environment — and many canola-growing areas currently have all three. Under “favourable environment,” sclerotinia requires moist soil conditions to germinate. The last few years have… Read More
Canola seedlings have experienced a tough start in many areas of the Prairies this year. In Manitoba and eastern Saskatchewan, the crop has had to come through flooding, broadcast seeding, compaction, crusting, and flea beetles (stay away, grasshoppers), while it’s been the opposite soil moisture scenario in drought-stricken parts of Alberta and western Saskatchewan. In… Read More
There are two main species of flea beetles across the Prairies: the striped flea beetle and the crucifer flea beetle. Both can have devastating impacts on the canola crop, however, they have a few differences between them. As Héctor Cárcamo, research scientist with Agriculture and Agri-Food Canada (AAFC) at Lethbridge, Alta., explains, the crucifier flea beetle… Read More
Validating economic thresholds for flea beetles can be tricky — especially when we know the damage the insect can do to the canola crop. Héctor Cárcamo, research scientist at Agriculture and Agri-Food Canada (AAFC) at Lethbridge, Alta., recently completed a study that confirms an economic threshold. The team at AAFC found that 25 per cent… Read More
With some insects, we may be confused as to why they have the name they do. When it comes to cutworms — this isn’t the case. It’s pretty “cut” and dry…as the pest will feed on the stems of the plant. Cutworms unfortunately don’t have terrific forecast maps, as Jack Payne of South Country Co-op… Read More
When it comes to seeding depth of canola, there are many different opinions and recommendations out there. While there may not be a right or wrong answer — did you know you can potentially mitigate flea beetle pressure through seeding depth? Flea beetles can be one of the most detrimental insect when it comes to… Read More
In a year when input prices have skyrocketed, producers are looking for ways to cut back where they can to maximize profits. When it comes to pesticides, is it possible to stretch or conserve product without sacrificing performance and efficiency? On this episode of RealAgriculture’s Canola School, research scientist and sprayer guru Tom Wolf shares tips… Read More
