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

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

Straight-cutting canola growers urged to be patient on desiccant spray

Straight-cutting canola growers urged to be patient on desiccant spray

Producers may be chomping to get the crop off the field, but experts say an early desiccant application in canola might mean loss of quality

Don’t jump the gun on canola desiccation. The growing number of farmers who are straight cutting canola are once again pondering the right time to cut off their growing season, a decision that Canola Council of Canada agronomist Angela Brackenreed says is always difficult, even for experienced producers.

Changing moisture conditions at flower had farmers hunting for answers on whether to spray for sclerotinia, or leave the fungicide alone.

Sclerotinia a moving target this season

Farmers faced a tougher than normal choice on whether to spray for sclerotinia this year

Whether to spray canola for sclerotinia is always a challenging choice, but this year was harder than usual. Dry soil gave little room for the disease to germinate early in the year through much of Manitoba, leaving producers to wonder if a spray pass was worth the expense, says Angela Brackenreed, of the Canola Council

Manitoba’s canola stands took a beating with hail in southern Manitoba June 14, but experts are optimistic about the chance of recovery.

Canola dodges the worst of the damage

The canola fields may look grim, but both Manitoba Agriculture and local agronomists from the Canola Council of Canada (CCC) say most fields will recover from a June 14 storm that dropped hail over southern Manitoba. “It almost hit it at an ideal time, because it’s just a visual impact right now,” Justine Cornelsen, CCC


Flea beetles on canola leaf

Ideal flea beetle weather hits canola fields hard

Flea beetle damage has been enough to tip the scales for some producers considering reseeding their canola

Canola growers are reaching for the insecticide or, in some cases, extra seed after a spring that has been friendly for the flea beetles, but less than optimal for the crop. Justine Cornelsen, western Manitoba agronomy specialist with the Canola Council of Canada, says she has heard some farmers intending to reseed after their first

Flea beetles are present in Manitoba canola fields every year, but this year’s infestation is worse than usual.

Worst year ever for flea beetles?

June 10 is the deadline for full crop insurance coverage in Canola Area 2

If you think flea beetles are worse this year, you’re not alone. “I haven’t done formal surveying, but I feel pretty confident in saying yes, it is absolutely worse this year,” Angela Brackenreed, the Canola Council of Canada’s eastern Manitoba agronomy specialist, said June 7. “From my personal experience, not that I am long in


Dry weather has been bad news for canola emergence, but good news for flea beetles.

Thin canola stands mean less margin for error for flea beetles

The Prairie Pest Monitoring Network warns that farmers may want to spray once flea beetles start eating a quarter or more of cotyledon leaf space

The flea beetles are out, and Manitoba Agriculture is reminding farmers to keep economic thresholds in mind when scouting their canola. Manitoba Agriculture oilseeds specialist Dane Froese says beetle management might need some adjusting, depending on crop emergence. At the same time, dry conditions have farmers casting a careful eye on stand numbers. Froese had

Manipulator OK’d for 2018 crop, progress on quinclorac

The list of products exporters don’t want farmers using on their crops is being revised

The list of chemicals Canadian farmers shouldn’t apply to their crops because they put markets at risk is expected to be shorter this growing season. Manipulator (chlormequat chloride), a plant growth regulator, has received a maximum residue limit (MRL) in the United States and an international MRL is expected to be set in July for

urges farmers to count stands in the fall during his CanoLAB talk in Dauphin
March 15.

Fall stand counts pegged as a better measure for canola production

CanoLAB speakers say it’s time to add a fall 
stand count to the schedule to see how close that target density really is

Few farmers track stand density after the combine rolls, but the Canola Council of Canada says those are the numbers that really count. “That’s going to give you your absolute measure of success,” Gregory Sekulic, agronomy specialist with the council, said. “When you’re talking about seed mortality, we quite commonly see in excess of 50

in weed identification in Dauphin March 15.

CanoLAB adds soybeans to the agenda

The two-day event hoped to get a better idea on managing canola 
and soybeans for growers who increasingly want to grow both

Growers were looking for more than just canola knowledge from CanoLAB this year. Soybeans also stole the show. Put on annually by canola commodity groups, CanoLAB is usually a major stop for everything from canola fertilization and weed control to disease pressures and beneficial insects. This was the first year, however, that the Manitoba Pulse
