MCGA members offered free blackleg testing

Follow these steps to find out more about the genetics

The Manitoba Canola Growers is offering its members a free blackleg gene test. Better gene classification will help growers match blackleg-resistant canola varieties to races of the fungus found in the field. Members can qualify for one free test each. MCGA is offering the tests, which ordinarily cost $200, under the Pest Surveillance Initiative, which



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

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

Damage to canola from frost is dependent on the seed moisture content and the time of the frost.

Assessing frost damage on crops

Fall frost information bulletin from Manitoba Agriculture

If frost does occur, the information below will give you some details to help assess any potential impact to crop yield and quality. The full impact of frost will not be obvious immediately. Several warm days may be required for the extent of leaf and crop damage to be evident. The magnitude of frost injury



Sub-zero temperatures descend on Manitoba

Special Crop Report due to early fall frost on Sept. 5

Sub-zero temperatures were recorded in Southwest, Northwest, Central and Interlake stations overnight. Sub-zero temperature and duration of temperature are important factors to consider for their effect on immature crops. Where frost occurred, crops susceptible at present maturity are canola, soybean and silage corn. Producers are cautioned that frost that occurred on greenfeed and corn can

Neonic phase-out may limit flea beetle control tools

CNS Canada — The phasing out of neonicotinoid seed treatments in Canada may cause problems for the country’s canola growers when dealing with flea beetles — but alternatives pesticides could fill the gap. Health Canada’s Pest Management Regulatory Agency (PMRA) is proposing that two neonicotinoid pesticides, clothianidin and thiamethoxam, be phased out over the next


A second case of clubroot has been discovered in the R. M. of Lorne according to Manitoba Agriculture’s Aug. 15 Manitoba Insect & Disease Update.

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

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

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

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
