The Manitoba clubroot advantage

So far the transmission pattern for the disease suggests farmers in this province still have time to act

By
It looks like clubroot is moving just a bit differently in Manitoba and that could be good news for producers trying to slow or stop its spread. Bruce Gossen, a research scientist with Agriculture and Agri-Food Canada (AAFC), told the Manitoba agronomist conference earlier this winter there’s a clear pattern in the other Prairie provinces

Manitoba Agriculture tour offers insights and strategies on clubroot management

By
Clubroot isn’t yet a significant challenge for Manitoba canola growers. But the emphasis these days is on ‘yet.’ The first cases in the province were discovered in 2013, and more cases are popping up every year. Last August Manitoba Agriculture announced a further eight. That demonstrates how the disease has persistently and stubbornly survived and

Twelve tips to clubroot management

By
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
Clubroot, which causes bulbous swellings on canola roots, has become infamous for its impact on yield.

Manitoba has another confirmed case of clubroot

A third case in the RM of Lorne brings the total so far this year to 10

By
A third case of clubroot was recently found in the Rural Municipality of Lorne, bringing the Manitoba total for the season to 10. Earlier this summer two other cases were confirmed in Lorne along with one in the Rural Municipality of Dufferin and six in the Rural Municipality of Pembina, Holly Derksen, Manitoba Agriculture field

New case of clubroot found in R.M. of Lorne

Manitoba Agriculture is asking farmers to report suspected cases of the soil-borne disease

By
A new case of clubroot has been found in the Rural Municipality of Lorne, Manitoba Agriculture says in its Aug. 15 Manitoba Insect & Disease Update. That brings the number of clubroot cases in Manitoba canola fields discovered so far this season to nine. “Manitoba Agriculture continues to encourage growers to scout any areas in
The map shows positive clubroot findings by RMs, which have been highlighted to show the highest concentration of spores. This does not mean all fields in the RM have these concentrations. As spore concentrations can be highly variable within a field, the RM classification indicates only the maximum concentration found in any field in the RM. Further explanation on the concentration categories are as follows: RED = Symptoms observed: Clubroot symptoms have been observed in fields in this RM. Management to prevent continued buildup or spread of this pest should be implemented. ORANGE = 10,001 to 80,000 spores/gram soil: Spores have been found in fields in this RM at concentrations approaching levels known to cause field symptoms. Without management, concentrations may increase to where symptoms are visible. YELLOW = 1,001 to 10,000 spores/gram soil: Clubroot spores have been found in this RM at low to intermediate levels. With proper management, spore concentrations can decline. GREEN = zero to 1,000 spores/gram soil: Clubroot spores have not been detected, or detected at very low levels. At this concentration, clubroot is not a major concern, but fields should be monitored. Retesting is recommended within the next five years. It is generally reported that 100,000 spores/gram of soil are required to see symptoms under field conditions, but symptoms can still appear under favourable conditions. As less than 10 per cent of farms in Manitoba have been sampled, it is recommended that all fields be tested, regardless of RM classification.

Eight new clubroot cases found in Manitoba canola this year

Manitoba Agriculture wants to hear from farmers who suspect clubroot in their fields

By
Eight new cases of full-blown clubroot have been found in Manitoba canola fields so far this year but there are likely more. So farmers should be scouting and reporting suspected infections to Manitoba Agriculture, says Manitoba Agriculture pathologist Holly Derksen. “I would definitely say we don’t need to panic,” one of the farmers who discovered

Back in 2013, John Guelly discovered some dead canola plants with ominous-looking root galls at his Westlock-area farm. But even though clubroot was already known to be in his area, he hadn’t seen it himself, and he wasn’t sure what it looked like. People were secretive about the disease, he told farmers, agronomists and other

In the early 1980s, the wheat board developed an idea called the Market Assurance Plan (MAP). That was back when there were perennial transport bottlenecks and the whole crop could sometimes not move by the end of the crop year. Even if it could move in total, it could be feast or famine for supply
