Warm weather and early planting are some of the factors contributing to big winter canola plants heading into winter in November 2024. What can we expect this winter and next spring in fields that have huge plants? […]
In 2024 there were approximately 50,500 acres of canola insured by Agricorp. This includes winter canola seeded in the fall of 2023 and spring canola seeded in 2024, both of which had a modest increase in acreage compared to last year. Spring Canola Acres of spring canola in Temiskaming District, where the greatest acreage of […]
By Tracey Baute and Meghan Moran Spring canola producers will have the option of Buteo (flupyradifurone) or Lumiderm (cyantraniliprole) insecticide seed treatment on some varieties this year, in addition to the Helix Vibrance seed treatment. Producers have reported they prefer Buteo for managing flea beetles, but that is the only insect on the Buteo label. […]
Clubroot is no longer hiding. Canola producers in Northeastern Ontario have reported symptoms over the past 5 to 8 years and there were certainly fields with yield loss in the past few years that generated concern. But in 2024 above-ground symptoms were more obvious in Temiskaming District. Patches in fields matured early or died prior […]
Winter canola harvest will be happening soon in the southern counties of Ontario. Some producers and the researchers at AAFC Harrow have already applied a pre-harvest herbicide last week. Here are some resources on staging the crop for harvest. Resources from Canola Council of Canada and Kansas State U have been used to develop this […]
It is safe to call 2024 a good pest year. Mild winters and warm springs tend to help pests overwinter well or expand their range further than usually and get ahead of crops when soil conditions delay planting. Armyworm and cereal leaf beetle are continuing to show up in some wheat fields, while some grubs […]
A warmer than normal winter coupled with dry weather through February has led to surprisingly good field conditions in much of southern Ontario. While it looks like it could be an early spring, we know that the weather can change rapidly this time of year. Some are questioning whether it makes sense to take advantage […]
Many Ontario canola producers tank mix boron with a preventative white mould fungicide and apply it at 20-50% bloom. We took a closer look at whether foliar boron reduces flower abortion or improves yield. […]
Flowering has begun in many winter canola fields. Two key pests in winter canola at this growth stage are cabbage seedpod weevil (CSW) and white mould (a.k.a. Sclerotinia stem rot). These are also both pests of spring canola, and the management recommendations are the same for both types of canola. Cabbage Seedpod Weevil When to […]
Five canola specialists from outside the province were invited to join Ontario producers and agronomists and share their canola expertise in a series of online meetings held from February 9 to March 9, 2022.Those meetings were recorded and the videos are posted below. Each meeting starts with a presentation by the guest speaker (approx. 30 […]
At a recent virtual speaker series on canola topics, John Heard, Soil Specialist with Manitoba Ag, joined Ontario growers to answer questions on fertilizing canola. A canola crop needs 3 to 3.5 lbs of nitrogen (N) per bushel of grain produced. In spring canola production in Ontario, granular fertilizer is typically broadcast ahead of planting. […]
Vegetative/Reproductive Overwintering Growth resumes when average temperatures reach 5°C but will be slow until it is consistently warm. Leaves may have rotted off or be discoloured but the centre of the rosette should be green. Determine the population of healthy plants. 5 plants/ft2 or more is ideal. 3-4 plants/ft2 is acceptable. 1-2 plants/ft2 can be […]
Planting corn after a crop of canola is generally not recommended, and the reason why has to do with beneficial fungi living in the soil. However, some studies and anecdotal experience in Ontario have shown that this rotation is not always problematic. Arbuscular mycorrhizal fungi (AMF) Many crops we grow, including corn, have a symbiotic […]
Scouts and agronomists may put biosecurity measures in place with a certain disease or crop in mind, but should ensure protocols are in place each and every time you walk fields. Crops are grown in rotation, so the soil in corn fields may contain soybean cyst nematode and soil in wheat fields may contain clubroot […]
This article was written by Dwiti Mistry, Canola & Dry Bean Research Assistant The major canola insect Brassicogethes viridescens, or the pollen beetle, is of growing concern in Canada as it has the potential to significantly impact yield from canola crops. The pollen beetle is a known canola pest in Europe and has also been […]
