Clubroot Distribution Map (2009-2014)


Map shows positive clubroot findings by Rural Municipality, discovered through laboratory testing for presence of clubroot spores in soil and/or positive confirmation of clubroot symptomatic plants.  Testing was done from 2009-2014 and is still considered limited.  Positive findings have been at low spore concentrations and sporadic throughout the province. As more fields are sampled, the map will be updated.

As less than 5% of farms in Manitoba have been tested, it is recommended that all fields be tested to determine if clubroot spores are present, regardless of RM classification. To date, clubroot has been confirmed in 48 Manitoba fields.
Clubroot is a soil-borne pest that can move from field to field on both agricultural and non-agricultural equipment. Specific biosecurity activities to minimize the spread of clubroot will differ by the known levels of clubroot DNA found within the field.  MAFRD has a series of suggestions for all industries operating on agricultural land to minimize the potential of spread on the Crop Biosecurity page.

AAFC and MAFRD Invest in New Canola Research Lab Focused on Plant Pest Surveillance

The Canada and Manitoba governments have provided $250,000 in research funding and $969,000 for equipment to help identify and address problems caused by canola diseases and pests, Federal Agriculture Minister Gerry Ritz and Manitoba Agriculture, Food and Rural Development Minister Ron Kostyshyn announced today.

“The canola industry is an important economic driver, and our government is working to ensure farmers and producers have the tools they need to grow their business,” said Minister Ritz. “This investment will support research into disease prevention and resistance in canola, helping the sector remain profitable and sustainable.”

The Manitoba government will purchase 60 new automated weather stations and place them across the province, adding to an existing network to provide additional accurate and detailed weather information, Infrastructure and Transportation Minister Steve Ashton announced today.

“Significant weather events can affect thousands of people provincewide so we are investing in new equipment to ensure Manitobans have the most up-to-date weather information possible,” said Minister Ashton.  “These weather stations will improve our ability to forecast floods and droughts, fight forest fires and ensure Manitoba’s farmers can access the detailed weather information they need.”

The new weather stations, which will begin to be installed this fall, will include all-season precipitation gauges to collect snow and rainfall precipitation to improve flood forecasting related to spring thaws and rainfall-driven events.  They will transmit hourly data on air temperature, humidity, rainfall and soil temperature.

The minister noted 20 stations will be placed in areas at risk for forest fires to support Manitoba’s firefighting prevention programs.  The other 40 stations will be located in agricultural areas to enhance Manitoba’s agro-meteorology program, which provides weather-related information and other tools to producers at no charge, which is then used for their crop and land-management decisions.  The new weather stations will also improve the Manitoba government’s ability to report on crop and soil conditions, assess risks from crop diseases and insects, and support decision-making for the crop-residue burning program.

“Everyone likes to talk about the weather, but these new automated stations will provide critical information for farmers as it guides their decisions that can sometimes mean the difference between profit and loss,” said Agriculture, Food and Rural Development Minister Ron Kostyshyn.  “More weather stations will result in more accurate, timely information and better resources for producers.”

The expansion of the weather station network was a recommendation from the 2011 Flood Review Task Force.  Minister Ashton noted meteorological data from all weather stations across the province will be used to help officials assess and forecast weather events such as heavy rainfall that may lead to flooding.

In addition to Environment Canada weather stations, Manitoba currently operates 50 permanent weather stations and 20 seasonal weather stations.  All of the new weather stations will meet international measurement standards to ensure accuracy.

Glyphosate Resistant (GR) Kochia Confirmed in Manitoba

Manitoba Agriculture, Food and Rural Development (MAFRD) jointly conducted a kochia survey across Manitoba in the fall of 2013 in with Agriculture and Agri-Food Canada (Saskatoon Research Centre) and the University of Manitoba, funded by the Western Grains Research Foundation and BASF Canada.
Plants from 283 different kochia populations were harvested, thrashed and planted over the winter. The resulting seedlings were tested for glyphosate resistance.  Kochia plants from two of the 283 sites were found to be glyphosate resistant (GR).  Both sites were in the Red River Valley.  Finding GR kochia was not unexpected as previous surveys in Alberta and Saskatchewan, North Dakota, South Dakota and Minnesota, have all identified GR kochia.
Herbicide resistant weeds are not a new issue in Manitoba, as Group 2 resistant kochia and Group 3 resistant green foxtail populations were identified in 1988.  However, resistance to glyphosate is new and it remains an important herbicide in Manitoba crop production systems.
If GR kochia populations become more common in the province, it will result in added management skills and expense for Manitoba farmers.  In-crop control of GR kochia can be difficult in broadleaf crops like canola, soybean or pulses and pre-seed or pre-emergent treatments may be necessary for adequate control.
As GR kochia has been found in less than one per cent of the sites sampled, Manitoba farmers have an opportunity to minimize the spread of this weed. Farmers should consider reducing the number of glyphosate applications in a single season and incorporate non-glyphosate herbicides in weed management programs when growing glyphosate-tolerant crops.  Farmers will also need to incorporate non-herbicidal measures like crop rotation, tillage and manual weeding if necessary to control populations.
Moving forward, MAFRD staff will continue to monitor the two sites where GR kochia was found and work with the affected and neighbouring producers this spring to discuss possible containment procedures. The department will also develop an extension program on herbicide-tolerant weeds, using GR kochia as an example.  The program will be aimed at industry agronomists, grower associations and producers and is expected to be ready later this spring.
