Recently, CANTERRA SEEDS announced the release of CS2000, a new canola hybrid which independent, third-party, testing has shown to have an improved level of clubroot tolerance. In addition to resistance to the dominant 2, 3, 5, 6 and 8 pathotypes, CS2000 has an intermediate level of reaction to the new 5x pathotype.
The intermediate reaction is a new term to many growers, and they may be unfamiliar with what this means. According to Dr. Stephen Strelkov of the University of Alberta, and the Pathology sub-committee of the Western Canadian Canola/Rapeseed Recommending Committee (WCC/RCC), intermediate reaction is a level of resistance between 30-69%. The scale is described as:
- <30% reaction – Resistant
- 30 – 69% reaction – Intermediate Reaction
- >70% reaction – Susceptible
As with resistance to any canola disease, the intermediate reaction to the 5x pathotype is not a silver bullet. Growers are strongly encouraged to use all best management practices for clubroot including sanitation of equipment, crop rotations and growing resistant varieties.
Disease resistance in canola varieties is a key component of canola production and understanding management of disease resistance and its impact on canola yield is important for sustainable, profitable canola production.
CANTERRA SEEDS fully supports the ongoing research and testing of all canola related diseases, like blackleg, sclerotinia, and clubroot in order to provide canola producers and the value chain with varieties with improved yield and profitability.
CS2000 - August, 2014
Earlier today, CANTERRA SEEDS officially launched CS2000, a new clubroot resistant hybrid. While there are a number of clubroot resistant hybrids currently on the market, CS2000 offers something completely new for growers.
Clubroot was first found in central Alberta more than a decade ago. The spread of the soil-borne disease has been prolific, and was reported in more than 1,800 fields in 36 counties since it was first discovered. Management practices include knocking soil off vehicles leaving fields, cleaning equipment, planting resistant varieties and extending canola rotations in clubroot areas. Despite these efforts, the spread of the disease seems to be continuing, as it was confirmed in four new Alberta municipalities last year. Isolated incidents of clubroot have also been found in Saskatchewan, Manitoba and North Dakota.
The clubroot resistant trait has been available in canola varieties since 2009, and has quickly become one of the most important clubroot management tools used by farmers. However, in 2013, a new virulent strain of clubroot was found in a field north of Edmonton. The new 5x pathotype is causing concern, as work by Dr. Stephen Strelkov from the University of Alberta identified that all western Canadian varieties are susceptible to the new strain of the disease.
But that is all about to change.
CS2000, which will be available to growers this spring, will have the most comprehensive clubroot resistance package on the market. In replicated greenhouse trials, Strelkov confirmed that CS2000 has resistance to the pathotypes 2, 3, 5, 6 and 8. In addition, CS2000 exhibited an intermediate reaction to a new strain of the pathogen that has the ability to overcome currently used sources of resistance (pathotype 5x, identified in central Alberta). Strelkov also added that he has not seen this level of resistance in any other canola varieties, and is encouraged by this result.
CS2000 will be the first canola on the market to offer any level of resistance to 5x, and could prove an important management tool for growers. The variety also has excellent yields, standability and agronomic characteristics.

If I asked you where Bentley barley was grown, what would your first guess be? I can pretty safely assume you wouldn’t have thought “Vancouver Island”, but that is one of the many places you can find it, in this case being grown by producers who have partnered with Phillips Brewing Co to produce barley for their malts. I chatted for a while with Matthew Phillips, who is the owner of the brewery, about his passion for beer, his choice of Bentley as an ingredient, and what it means to him to see his ingredients all the way through the chain.
In his own words, he was “drawn to beer in university” which is not something particularly unique. It was once all of his projects started to turn in the direction of fermentation that he realised he had a passion. A job helping out at the local brew house, followed by a couple more jobs and both small and large breweries, further strengthened his interest. After deciding he wanted more control over the types of beer he made, he started his own brewery in 2001.
I asked Matt if he could describe what it was that made Bentley a preferred variety for their beers. He said that there are a couple of challenges associated with the fact that they use 100% malt barley in their beers.
For those outside of the agriculture marketing world, the Best of CAMA might not mean anything. To fill you in, this is basically the Oscars of agriculture marketing in Canada. It's a fancy evening where the who's who of the top agencies in Canada get together to highlight the best work of the past year. You can check out this year's Ottawa event here.
At CANTERRA SEEDS we work very closely with Think Shift, an agency based here in Winnipeg. We've worked with them for almost ten years, and they've been with us through many ups and downs over the years (mostly ups!). They are a strategic partner for our business, and are a valued member of our marketing team.
This year Think Shift was nominated for awards in a number of categories at the Best of CAMA, including point of purchase material for our canola bag redesign!

Congratulations to Think Shift, and thanks to the team at CANTERRA SEEDS who worked on the bag redesign. We didn't take top spot in the category, but a runner-up merit award isn't too shabby.
Jesse Meyer is our Territory Manager in the Peace River. He gathered observations about straight cutting canola in the Peace this year from his own farm, and from discussions with customers. Please note CANTERRA SEEDS has not done analytical testing to measure the effectiveness of straight cutting vs. swathing CANTERRA 1990, and Jesse's comments are not meant as an official recommendation.
Straight Combining Canola Gaining Popularity in the Peace
This past harvest there was more straight combined canola acres in the Peace Region than ever before, and it is gaining popularity with growers. By doing one less pass in the field and allowing the plant to mature fully, many farmers feel like they are gaining vs swathing. Liberty link canola seems to be the system of choice for growers who decide to straight combine, because they are able to do a pre-harvest with glyphosate, although Roundup Ready canola is gaining popularity as well. Just recently, Heat from BASF was registered as a pre-harvest on canola, and farmers have had good results from that application. It acts quickly and evens out the field. Reglone from Syngenta has also been used, but with less success. Although many farmers do use a pre-harvest herbicide, it is not necessary, canola will dry on its own. This past year a heavy, early, September frost killed all the canola, much like a herbicide would.
Green Seed Issues
Green seed was an issue this past year. If the canola was at 60% colour change when the frost came, green seed was minimal between the straight combined or the swathed. Swathing seems to only lessen the risk of frost if you are swathing before ideal colour change…less than 60%.
Types of Headers
Most growers are using draper headers on their combines, and that works well. A cross auger up top would help the flow in heavy canola but is not mandatory. Auger headers work very well because they grab the crop. There has been lots of discussion about headers where you can extend cutter bar and have side shears to reduce shatter loss. I have never worked with these, but understand they are a significant amount of money. The headers that you use for cereals will work for canola. A grower should pull the reel back as far as they can to the back of the header, and run the reel slowly to minimize shatter.
Shattering was minimal when it was around 10% moisture, but as the canola got dryer the risk of shattering increased. At the same time, swaths did blow in the wind and shattering was significant in those situations as well.
Advantages of Each Method
One of the biggest advantages of straight combining is that if it rains, the standing canola dries much quicker and gets you back in the field harvesting quicker. The advantage to swathing is that it does get you started with harvesting canola sooner by approximately a week, and that is a significant. So I believe a blend of both swathing and straight combining is important. It spreads the grower’s workload and spreads their risk - there are risks and advantages to both methods.
Experience with CANTERRA SEEDS canola
Several growers in the Peace, including ourselves, straight combined CANTERRA 1990 this year, and the variety worked very well. It has a nice lean for netting, and shattering seemed to be minimal, even in strong winds. One grower I know grew CANTERRA 1990, 73-45, and 45H29, and said the CANTERRA 1990 was the best canola for straight combining in his experience.
These were just my observations from one year of straight combing and every year is different, others may have had different experiences than I have had.
We will continue to straight combine canola, and I believe it will gain popularity on many farms.
