DeKalb pulls two ‘inconsistent’ canolas off market

Up against an “inconsistency of grower experiences” with the seeds’ yields in 2019, Bayer Canada is yanking two of its DeKalb TruFlex canola hybrids from the market. DeKalb’s DKTF 92 SC and DKTF 94 CR will not be available for 2020, Bayer said. Canola growers who have already booked those seeds for this spring are […] Read more

John Guelly tweeted this photo during this year’s harvest with the warning: “When ur out swathing, spraying or harvesting, keep an eye out 4 patches that look brown & dead like this.” Although clubroot wasn’t the cause in this case, taking a proactive approach is critical to managing the disease, which is continuing its relentless march across the province.

The Year That Was: Clubroot continued its deadly march in 2019

The disease didn't make the headlines in 2019 but its assault on Alberta continued

The rapid spread of clubroot in the last decade will continue in the coming one if canola growers don’t start to get ahead of the disease. “The resistance is being overcome already, and some of those cases are pretty significant and serious infestations,” said Dan Orchard, agronomy specialist with the Canola Council of Canada. “In […] Read more


The discovery of a new strain of clubroot in Manitoba is a reminder that all canola growers need to have a clubroot management plan, the canola council says.

New clubroot strain found in Manitoba sends a message to all canola growers

Discovery is a reminder growers need to ‘take this disease seriously and implement clubroot management plans’

The discovery of a new clubroot strain not controlled by traditional resistant canola varieties underscores the need to be proactive in keeping clubroot spore numbers low. “This is yet another cue for the industry to continue to take this disease seriously and implement clubroot management plans,” said Dan Orchard, agronomy specialist with the Canola Council […] Read more

Clubroot able to beat resistant canola reaches Manitoba

A strain of clubroot able to club the roots of some resistant canola varieties has made its way east to Manitoba. Manitoba’s agriculture department reported Friday that clubroot pathotype 3A — a strain that can “overcome some first-generation sources of genetic resistance” in commercial canola — has been positively identified in the south-central rural municipality […] Read more


New video on how to manage clubroot

The Canola Council of Canada has a new clubroot video focusing on key management strategies for dealing with the disease. The 15-minute video outlines steps for minimizing the risk of introducing the disease-causing pathogen to a farm, including the three stages for cleaning equipment so it doesn’t bring contaminated soil to a field. It also […] Read more

Clubroot galls are the sure sign the disease is present, but dead patches in the field should also be easy to spot at swathing time. 

Wind seems to be the clubroot culprit in Manitoba

Researcher urges producers to watch for early infestations and get on them quickly

It looks like clubroot is moving a bit differently on the east side of the Prairies. In Alberta, clubroot is showing up a lot at field entrances (in 90 per cent of the infected fields, according to one study), which suggests equipment is the main culprit in its spread. It’s a similar pattern in Saskatchewan […] Read more


This plant was found in 2017 in a trial plot of a resistant variety that Scott Keller was growing. It turns out that bags of resistant varieties aren’t pure — and so a percentage could be a non-resistant variety, said Keller. “So even resistant canola seed can help spread clubroot!” he said in an email. Still, experts and agronomists urge producers to seed resistant varieties — something Keller and Alberta Canola chair John Guelly say isn’t happening often enough.

In denial? Farmers ‘failing’ in battle against clubroot

Scott Keller has crunched acreage numbers and found tight rotations and susceptible varieties are commonplace

For the last three years, Scott Keller has been crunching acreage numbers from the provincial crop insurer — and he’s not liking what he sees. “To me, everything the researchers and the Canola Council (of Canada) is saying that farmers should do; they’re not even doing anything outside of just adopting the resistant varieties,” said […] Read more

A variety of crop types can add to the health of your soil.

Make a difference with good crop rotation

Benefits include lower disease control and fertilizer costs

One of the best tools to improve the bottom line, reduce future grief, and lower the risks of pests, disease and weeds is by using a diverse crop rotation. “A good crop rotation is one where there is an adequate variety of crops grown so that any one type of crop is grown only once […] Read more


This 2008 Canola Council of Canada video recommended producers “start at the top and work your way down to the root” when scouting for diseases. That meant clubroot — now the biggest threat to producers’ biggest money-maker — was discussed last (behind much less worrisome diseases such as alternaria and aster yellows). Agronomist Dan Orchard, shown here discussing sclerotinia, found the first confirmed case of clubroot but says back then, “we weren’t that scared of it.”

When it comes to the big two crop diseases, those really were the good old days

Fifteen years ago, a ‘funny’ new disease was found — today clubroot combined with fusarium is a killer one-two punch

Fifteen years ago, Dan Orchard was working as an agronomist at a retailer when he got a phone call about something “funny” in a customer’s canola field. The plants were prematurely ripened and the roots looked strange. Orchard had a hunch of what he was looking at, but a visit with a plant pathologist confirmed […] Read more

Twelve tips to clubroot management

There are several key management tools producers need to apply to minimize the risk of clubroot either reaching a damaging level, and/or to reduce a heavy spore load of the pathogen in the soil to a tolerable level (about 1,000 spores or less per gram or teaspoon of soil will not affect crop performance). The[...]
