Numbers of diamondback moths have increased in Western Canada over the past couple of weeks, in part due to the dry weather and strong winds. In some areas where the canola is still in late bloom, they are causing a fair amount of damage. Héctor Cárcamo, entomologist with Agriculture and Agri-Food Canada, says the key to… Read More

When it comes to assessing canola maturity at this time of eyar, it can be tricky to see what’s what, especially when it comes to a thick canola crop. In this Canola School episode, Keith Gabert, agronomy specialist with the Canola Council of Canada, shares a tip for finding the main stem — a trick… Read More
When you see the stem rot in the field, it’s too late. And that’s just one of the reasons why managing sclerotinia is a challenge, as exerienced in 2016, a severe year for the disease in canola fields in Western Canada. In this Canola School episode, we talk to Michael Harding, plant pathologist with Alberta… Read More
Aster yellows is a ‘phytoplasma’ disease carried by aster leafhoppers. It’s known for the odd-shaped canola pods it causes later in the growing season. Problems with aster yellows are hit and miss, depending on your area and the year. “We are kind of waiting for the next leafhopper infestation with aster yellows, the next big… Read More
Less than ideal conditions have slowed down canola development and left the crop vulnerable to tiny 2.5 millimetre beetles in some areas this spring. Flea beetles are the number one pest in canola on the Western Canadian Prairies. In this Canola School episode, we talk with Tyler Wist, entomologist with Agriculture and Agri-Food Canada in Saskatoon, about how… Read More
With the cooler soil temperatures we’ve been seeing across Western Canada, unwanted pests are beginning to show up in some fields. Alberta Agriculture and Forestry Insect Management Specialist Scott Meers says that early on in the season we should be keeping our eyes out for stand establishment insects such as cutworms and wireworms. There have been a… Read More
Canola seed in Canada could soon come with a label describing the variety’s blackleg disease resistance package, similar to the labeling system used in Australia. After around four years of discussions between seed companies, researchers, and growers, an agreement-in-principle has been reached on blackleg resistance labeling, says Clint Jurke, agronomy director with the Canola Council of Canada,… Read More
Seed companies are turning to new sources of resistance to protect canola against blackleg disease, as the pathogen population in Western Canada has adapted over the years. Until recently, most of the varieties marketed as “blackleg resistant” relied on what’s known as the Rlm3 gene, explains Sakaria Liban, pathologist with DL Seeds, in this episode of… Read More
The clubroot story in Western Canada continues to be written as researchers are finding additional strains of the pathogen that are capable of overcoming genetic resistance. So far, 13 new variants have been identified since the breakdown of resistance was first confirmed in 2013, explains Stephen Strelkov, plant pathology researcher at the University of Alberta. “We think resistance… Read More
There’s no long-term trend talk of any agriculture commodity sector, it seems, that doesn’t include at least some reference to China. After all, it’s not just a populous country, it’s a huge economic driver and consumer of Canadian agriculture products. Imagine, then, what it would mean to have the Chinese market closed, a market worth… Read More
