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

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

With a smartphone in their pocket, every farmer, farm employee, or agronomist is now also a photographer. The ability to share pictures from the field has dramatically improved how farmers and agronomists communicate and diagnose issues. However, the information gleaned from a cellphone photo can only be as good as the original picture. A poor photo won’t tell… Read More

Glyphosate-resistant kochia has started showing up in more of Western Canada, and as with other cases of resistance, it’s becoming evident you can’t rely on a single tool for too long. Minimizing resistant weed populations requires an integrated or diverse approach. The crop itself must help make survival difficult for potentially resistant weed seedlings, explains Rob… Read More
