What were the canola yield robbers in 2020?

Some farmers benefited from the environmental conditions while others were ready to put 2020 behind them

By
In 2020, canola fell more than 11 bushels short of the 52 bushels per acre yield target the Canola Council of Canada (CCC) hopes Canadian farmers can achieve by 2025. Though a handful of major factors held yield back last season, hot and dry conditions bit into the most acres, said CCC agronomy specialist Justine […] Read more

How to prevent a clubroot catastrophe

Some recommendations for all scenarios

By
The mentality amongst some of our Prairie canola growers is, “I’ll just wait until clubroot shows up and then I will seed a resistant variety.” Big mistake! Canola growers whose croplands are free of this destructive disease should be seeding resistant canola varieties right away. Yes, this year. Before clubroot shows up. I presently handle […] Read more

New canola varieties for 2021

Almost two dozen canola hybrids will be coming your way, some with improved shatter and clubroot resistance

By
Looking for the latest canola options? Twenty-three new hybrids will be hitting the market for western Canadian farmers in 2021. Strong standability, improved shatter resistance and clubroot resistance are major themes in the new lineup. Please note, the following list includes only brand new variety releases for 2021. BASF InVigor L357P is a pod shatter-reduction […] Read more

Steps to prevent and mitigate clubroot in your fields

Your guide to identification, risk reduction and disease control

By
Clubroot is a serious soil-borne disease. If conditions are right, it can cause up to 100 per cent yield loss in canola. And while yield loss can be low when conditions aren’t favourable, the pathogen is hardy and easily overwinters in the tough Canadian climate. Come spring, resting spores not only germinate where they overwintered, […] Read more

Blackleg best management practices to keep disease levels low

Is blackleg increasing in your fields? Use BMPs to keep the disease at bay

By
For the longest time, yield loss due to blackleg has been significantly reduced through the use of disease-resistant canola varieties. However, those genetics were first introduced nearly 20 years ago and are now starting to be overcome. For a disease that has mostly been ignored by farmers, this means there is a need to reintroduce […] Read more

Clubroot able to beat resistant canola reaches Manitoba

By
A strain of clubroot able to club the roots of some resistant canola varieties has made its way east to Manitoba. Manitoba’s agriculture department reported Friday that clubroot pathotype 3A — a strain that can “overcome some first-generation sources of genetic resistance” in commercial canola — has been positively identified in the south-central rural municipality […] Read more
Blackleg disease incidence in the crop was medium to medium-high. However, I thought the blackleg was compounding another, larger issue in this crop. Some of the roots looked funny when we pulled the plants out of the soil, almost like there was an abundance of organic matter or extra loamy soil collecting at the roots.

Crop advisor casebook: Irregular canola pod shatter a mystery

A Crop Advisor's Solution from the August 27, 2019 issue of Grainews

By
Dave, who farms 6,000 acres of wheat, barley, peas and canola in Central Alberta, was trying out a new canola seed variety, which was in its first market year. The variety had clubroot resistance and had also been selected for some pod shatter tolerance. Throughout the growing season, the canola crop had developed normally, and […] Read more

Disease-free boots and a testing tool

Spotted in the field: homemade ideas that don't cost a lot, but work

By
They are two separate topics completely, but here are a couple of good ideas that western Canadian field specialists came up with for sanitizing rubber boots to reduce the risk of spreading clubroot (or any soil borne disease), and a handy homemade sample collection tool for measuring spray volumes when calibrating a field sprayer. Boot […] Read more

Resistant to resistance?

If you don’t have clubroot, should you be planting clubroot-resistant canola?

By
Should a farmer who regularly practises a one-in-four-year rotation of canola in an area without confirmed clubroot be growing clubroot-resistant (CR) cultivars of canola? This was a question I asked at a canola agronomy meeting last November. At that time, I was describing my own farm and I thought the answer would be straightforward, but I received conflicting responses. One canola company representative said […] Read more
