Scientific research in Western Canada has identified three factors that increase the risk of canola yield loss in short rotations. They are blackleg, clubroot and cabbage root maggot. Clubroot will drive the need for longer breaks between canola crops on more and more farms.
A pesticide rinsate biobed can prevent the environmental contamination of surface and groundwater by pesticides. Instead of being disposed of directly on land, at the edge of a field or elsewhere, the rinsate from the sprayer can be applied to the biobed (so it is contained).
Step 1. Sample Collection The ideal time to pull and assess plants for blackleg infection is at 60% seed colour change, which is around swath timing. Plants should still be green. Cut just below the crown of the plant into the root material to assess. “Look for black discolouration within the hypocotyl tissue, often appearing in a wedge pattern. If …
Healthy-looking plants can still have galls that release millions, possibly billions of spores.
The Saskatchewan clubroot distribution map includes all findings of clubroot and detections of the clubroot pathogen from 2008 to 2018.
At the workshop, the 200 attendees were urged to think about actions they can take to reduce the impact of clubroot on their farms, businesses and communities. These actions includes crop rotations, sanitation, resistant varieties, reduced tillage and scouting.
Here are the clubroot-resistant (CR) canola varieties currently available in Western Canada.
Use clubroot-resistant (CR) varieties as soon as clubroot arrives in the area. The CR trait will prevent most infection, which will help to keep spore counts low in fields that already have lower counts. With fewer resting spores in the soil, the risk of building up virulent pathotypes is reduced. List of CR canola varieties Use the following checklist to …
The Canola Council of Canada, Alberta Canola, and Rocky View County are hosting a Southern Alberta Clubroot Response Workshop on Monday, January 7 at the Indus Hall.
When choosing canola hybrids for 2019, think through the yield, quality and profit achieved over the past few years and consider what factors may have reduced overall profitability. Add notes on harvestability. Then consider how seed traits could help manage any existing and potential challenges, reduce risk and improve profitability.
