Of the 36 unique clubroot pathotypes that have been found on the Prairies, 19 of them are able to overcome first-generation resistance, limiting plant growth and potential yield.

(Genetic) resistance is futile for new clubroot pathotypes

Over half of the unique clubroot pathotypes in Alberta able to overcome first-generation resistance

By
Reading Time: 4 minutes New clubroot pathotypes are emerging in canola fields across the Prairies — and clubroot-resistant varieties might not be enough to stop the spread. “The most worrisome part about this is the fact that a lot of these new pathotypes are able to overcome traditional first-generation resistance,” said Keisha Hollman, who led the study at the […] Read more
Last year’s conditions mean this year’s weather will be the driver when it comes to crop diseases, says provincial research scientist Michael Harding. But keep close watch for clubroot and root rots (which continued to spread last year) and watch for fusarium head blight, which has laid low recently but could easily rebound in 2021.

Your 2021 disease forecast will depend on your weather forecast

Keep an eye out for the usual suspects in your crops this year if the weather turns wet, says researcher

By
Reading Time: 4 minutes Predicting which diseases will cause problems on your farm this year is a little like predicting the weather — you know it’s going to hit you, but you don’t know when or how bad it will be. And it doesn’t help that these two unpredictable forces often go hand in hand. “One of the primary […] Read more
A Burkard spore trap (and the adhesive tape used to capture spores) is demonstrated in this County of Vermilion River video. It can be found on YouTube by searching for ‘vermilion river clubroot.'

As clubroot grows in strength, counties boost their defences

Six municipalities have banded together to boost surveillance and encourage farmers to be proactive

By
Reading Time: 4 minutes Six partnering municipalities in the northeast region have stepped up their clubroot monitoring and are running an enhanced clubroot surveillance program. “There’s a lot of presence of clubroot in the Edmonton region. There’s a lot more traffic in that area. That’s where it was first discovered and is prevalent,” said Hannah Musterer, agricultural services technician […] Read more

DeKalb pulls two ‘inconsistent’ canolas off market

By
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

By
Reading Time: 5 minutes 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’

By
Reading Time: 3 minutes 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

By
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

By
Reading Time: < 1 minute 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

By
Reading Time: 3 minutes 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

By
Reading Time: 6 minutes 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
