The premise behind why a good healthy plant stand is important when battling flea beetles in canola is simple: the fewer beetles per plant, the less likely they’re going to damage more than 25 per cent of the total leaf area. In dry conditions, too much seed-placed fertilizer can hurt that plant stand and help… Read More

Clubroot has expanded its reach across the Prairies each year since it was first confirmed in a canola field in Alberta in 2003. Since then, the soil-borne disease has spread across the province and positive cases have popped up across parts of Saskatchewan and Manitoba. For Manitoba, what could have been a disaster of epic… Read More
One of the most commonly-used tools for fighting insect pests will be missing from the toolbox in many situations on Canadian farms again in 2024. There’s been no change to the label for products that contain lambda-cyhalothrin, such as Matador and Silencer, heading into the 2024 growing season, says Ian Epp, agronomy specialist with the… Read More
With any new crop pest or disease, it takes time to understand the problem and to develop best management practices. It’s been around a decade since verticillium stripe was first confirmed in Manitoba. Both awareness and prevalence of the disease have increased across the Prairies since then, but there are still gaps to be filled… Read More
It won’t be long before final decisions on seeding rate, seeding date, and pre-seed burndown are made. Every year holds a certain level of unknown, but a few key pests are proving to be a likely issue for the coming growing season. For this episode of the Canola School, Lyndsey Smith is joined by editor… Read More
Verticillium has been impacting canola crops in Manitoba for over a decade, but it is now spreading across the Canadian Prairies. According to Jeanette Gaultier of BASF, while verticillium was first detected in Manitoba around ten years ago, it has since been found in every canola growing region of Canada, except the Atlantic provinces. Verticillium… Read More
As canola harvest wraps up for another season, it’s an important time for growers and agronomists to get out into fields and scout for disease. Walking fields in the weeks after harvest helps paint a picture of what diseases may be lingering in the soil or crop residue, which can be important when considering a… Read More
Verticillium wilt is a well known global disease that impacts many different crops. Verticillium stripe, however, is a lesser-known disease and one impacting canola, specifically. They may have similar names, however, they are not nearly the same disease, and it’s important to know that when discussing the disease, says Clint Jurke of the Canola Council… Read More
Agronomic strategies that maximize fertilizer efficiency should be good for a farm’s financial bottom line and the environment, but specific decisions about how fertilizer is applied should be made with the overall outcome in mind, stresses Marla Riekman, soil management specialist with Manitoba Agriculture. The 4Rs — the right source at the right rate, right… Read More
Advancements in RNA interference (RNAi) technology could soon unlock new tools for managing canola pests and pathogens, such as sclerotinia and flea beetles. RNAi — ribonucleic acid interference — involves targeting specific RNA sequences in a disease or pest, rather than targeting entire proteins or enzymes, as is the case with current pesticides. It’s a… Read More
