Clubroot Identified in Rocky View County Southeast of Calgary3 weeks ago -
Clubroot has been identified in canola southeast of Calgary. Although clubroot has been found in various counties in Alberta since 2003, this is the first year the disease has been confirmed in Rocky View County.
This fall, southern Alberta canola growers should be especially diligent in scouting their canola fields for clubroot and should consider deploying resistant varieties in future canola production cycles.
Identifying clubroot as early as possible and keeping the pathogen’s spores from spreading are important steps in long-term clubroot management. With early detection, growers can take steps to contain and minimize spore loads and protect their fields. ANY method of soil movement can move the clubroot pathogen’s spores, such as tillage, dirt/dust on equipment and straw, wind or water erosion, and even animals.
Under high disease pressure, above-ground symptoms of clubroot can include stunted growth, wilting and premature ripening. These symptoms should not be mistaken for drought stress, which was common throughout southern Alberta this year. Start looking for the disease around field entrances and in areas with higher moisture or where soil movement may have occurred in a field’s history. Proper diagnosis should always include digging up plants to check for gall formation on roots. This time of year, many galls will likely have matured and decomposed into a peat-moss-like (or sawdust-like) substance around roots. If growers or agronomists find galls or a substance that looks like it might have been galls, samples can be sent to a lab for proper diagnosis. Find the labs list at clubroot.ca.

Tips for Drying Tough and Damp Canola3 weeks ago -
The ideal goal for safe long-term storage is to have canola rest in the bin at 8% moisture and less than 15°C.
No matter how good the harvest weather or how dry the harvested crop, all canola should be conditioned after it goes into the bin.
For tough and damp canola, the spoilage risk is much higher. Canola is considered “tough” at moisture levels between 10% and 12.5%. “Damp” is anything above that. With tough canola, aeration with adequate airflow can be enough to dry it to safe storage levels as long as air has capacity to dry: warm with low relatively humidity (RH). At RH values above 70%, the equilibrium moisture content will be above 8% to 9%, meaning sufficient drying for safe long term storage is difficult to achieve. Drying canola with aeration alone also requires sufficient air flow* and time to move the drying front to the top of the grain mass. Damp canola will require heated air drying and rigorous management to condition it for safe storage.
HEATED AIR DRYING:
Dry canola as soon as possible. While waiting, aerate continuously if possible and move damp canola back and forth between storage facilities to prevent spoilage. The combination of aeration and movement is ideal.
Have the right equipment. Continuous flow or re-circulating batch drying systems are preferable. They reduce the potential for seed damage from heating and allow for slightly higher drying temperatures. For very damp canola, growers may prefer to run the grain through twice at a lower temperature to prevent seed damage and reduce the risk of fires. Also, if the dryer has screens, make sure the screen size is small enough to hold canola. Another option is to add heat to a bin aeration system. Talk to your bin and fan supplier for details.
Watch drying temperatures. Check the maximum safe drying temperature for your system, then reduce it by 11°C when working with damp canola as opposed to tough. As moisture content increases, it gets much easier to “cook” your canola in a heated air drying system.
Over dry canola slightly when using heated air. As grain cools when moved into storage, moisture content tends to rebound slightly. Over drying compensates for this. A general rule is to over dry by 0.1% for every point the grain is dried. For example, if canola is at 14% moisture and your target is 9%, over dry by 0.5 percentage points to 8.5%.
When returning warm, dried canola back to the bin, turn on the fans to cool it for safe storage. This could also allow for a bit more drying as drying can occur when cold air is introduced to a warm mass of grain.
NATURAL AIR DRYING:
Natural air drying (NAD) using aeration fans with adequate airflow can work as long as air has capacity to dry. NAD for tough or damp canola is not usually effective under late fall conditions when canola and outside air are both cold. In these conditions, reaching dry equilibrium moisture levels often takes too long to avoid spoilage in many cases.
Adding heat to an aeration system. The general recommendation for this method is to increase air temperature to no more than 15-20°C. PAMI storage researcher Joy Agnew notes: “Hotter is NOT always better when using natural air drying with heat. You must match heat addition with your fan capacity. The more cubic feet per minute the fan blows, the more heat you can add. With typical NAD fans, a temperature increase of 10-20°C is max.” Also ensure fan airflow rate is sufficient for moisture removal — 0.5 cfm/bu or higher. Ensure the air is heated adequately. There’s no point in heating air if the amount of temperature increase won’t accomplish drying.
Temperature of the grain itself plays a role in the efficiency of NAD and NAD with supplemental heat. If the grain is already cool (less than 5°C), NAD and NAD with supplemental heat will initially add moisture to the grain; it will take some time before drying starts, but the bulk will warm up eventually and drying will be accomplished. If the grain is still warm (close to the temperature of the air you are introducing into the bin), then NAD plus supplemental heat can work very well. Increasing the temperature of the incoming air basically reduces the relative humidity (RH) of the incoming air (or increases the capacity of air to hold moisture) which will increase its efficiency of drying the grain. For every 10°C increase in air temperature, the RH is cut in half.
Can your fan move enough air? When conditioning tough or damp canola, make sure your aeration fan has the horsepower to work effectively. Insufficient air flow can result in a high moisture zone near the top of the bin that can initiate spoilage.
If the fan can’t move enough air, take out some grain. The greater the depth of canola in the bin, the more fan capacity you will need to move air through it effectively. Large diameter bins that provide uniform air flow through a perforated floor may have an advantage when handling damp grain. If you suspect the air flow is insufficient, remove some canola to reduce the depth. This offers two other benefits: It disrupts any high moisture areas that are developing. And it can flatten the cone, making the depth of grain more consistent throughout the bin.
Ventilate the bin. Proper ventilation at the top of the bin to allow for escape of the warm moist air is very important, especially for large bins and especially when adding supplemental heat since the moisture removal rate is so much higher when heat is added. Inadequate ventilation in the headspace will result in condensation on the top layers of grain.
What about blending dry and damp canola? If considering blending in an attempt to bring damp canola down to tough, be very careful. It is possible you could just be putting your dry canola at risk, as the transfer of moisture from seed to seed is a slow process.
Monitor regularly. This is good advice for all canola. Be extra careful with canola that goes into the bin warm and tough this week.
*PAMI ran a trial in wheat comparing two bins using 0.1 cfm/bu, two bins using 0.5 cfm/bu and two bins using 1 cfm/bu. All bins started with the same temperature and moisture content (17%). Bins with 0.5 and 1 cfm/bu air flow ended up between 14% and 15% moisture, but the bin with 0.1 cfm/bu lost very little moisture and ended up around 16.5%.

Top 10 Things To Look For During Harvest Down Days1 month ago -
Weather delays? Canola not ready to swath? Waiting for the next crops to be ready to combine? Take advantage of harvest down days to check canola fields for the following:
1. Clubroot. Don’t wait for obvious dead patches. Check random plants in high risk areas to see if they have clubs. If they do have clubs, destroy as many as you can. It may seem a daunting task and you won’t find them all with a random search, but the more you destroy now, the fewer spores will remain. Consider this: Seed growers spend weeks roguing crops for weeds and off-types. Ridding a field of clubroot deserves the same level of attention. Read more scouting tips. Send samples for DNA analysis. Top 10 observations from the International Clubroot Workshop.
2. Blackleg. Fields that started the season with moist soil conditions and fields that had hail early in the season could be at higher risk for yield-damaging blackleg. Fields in a tight canola rotation are also at higher risk. Clip stems to check for blackleg severity. Do 50 random stems (not just clearly damaged stems) to get a true picture of incidence (% of plants infected) and severity (average blackleg rating) for the field. If average severity is moving beyond 1.5 toward 2 or more, this is a clear sign that the blackleg resistance in the variety is no longer appropriate for this particular field. The blackleg pathogen population has shifted and R-gene rotation will be required the next time canola is grown on that field – unless the plan is to take a three-year break from canola. When making field scouting notes, include the variety name. Read more. See the article on race ID tests for blackleg.
3. Sclerotinia stem rot. Dry conditions will mean lower levels of sclerotinia across most regions this year, but what about your fields? Checking sclerotinia levels now will help assess fungicide application decisions. Read more. Take our very short survey on sclerotinia stem rot action and DNA petal tests.
4. Other diseases like grey stem or verticillium. Blackleg can sometimes be confused with root/foot rot or grey stem and sometimes verticillium. How to ID various diseases that can be found in canola this time of year. Read an article specific to identifying verticillium.
5. Plant density assessment. Plant counts can drop 10-15% through the season. If more severe than that, check scouting notes and consider the most likely reasons – Insects? Weather? Disease? Overcrowding? – and whether there’s a profit-improving way to prevent this. Seed choice may be part of the solution. If counts increase, which is also possible, take a close look at all plants in the harvest count to see how many are actually contributing to yield. Small spindly plants that emerged well after all the others may not have that many pods, and should not be included in the count. Another angle is to see how plant density may be affecting days to maturity. Big plants due to low density mean more branches and longer maturity. Read more.
6. Insects. You might still find bertha armyworm, lygus, flea beetles, grasshoppers and even cutworms at work this late in the season. But with harvest so close, pre-harvest intervals will be a concern if populations are near spray thresholds.
7. Insect damage. Seeing clear evidence of insect chewing on pods, in pods, on leaves and stems? If damage is enough to cause noticeable in yield loss, it may inspire a closer look next year.
8. How are varieties performing? Seed decisions for next year are already being made. Aside from yield (which is yet to be determined), how did this year’s varieties work out in terms of disease resistance, height, lodging? Is the pod shatter trait, if you went that way, also showing benefits for pod integrity after late-season hail and frost? Tool to help with seed decisions.
9. Review your notes on the season. Problems from earlier in the season can be tricky to diagnose this late, which is why keeping notes on observations all season long is so helpful. Review the notes from each field and add missing details now (while it might be fresh) rather than waiting until winter. Read more.
10. Weeds. Are those patches herbicide resistant and to what? Or are they just escapes?
—Herbicide resistant weeds tend to be in patches with only one weed species present. Other weeds were controlled while this particular species-specific patch was not. Herbicide-resistant weeds also tend to be in patches of irregular shape, starting off as one weed and going out from there as seeds shell out or the combine spreads them around. In the case of glyphosate-resistant kochia, plants are often in long lines as the resistant parent tumbled along dropping seeds. Wild oats will be in patches that spread out from the original resistant plants.
—Escapes tend to be multiple weed species. Weeds under the canopy may have missed herbicide contact, and these will usually be more than one species. Patches of escapes also tend to be in clear shapes, perhaps in arcs in headlands where the sprayer missed on a turn. Read more.
If weed patches could cause problems for straight combining, pre-harvest herbicide may be required to improve harvest logistics.

Government of Canada Invests Over $12 Million to Advance Innovation and Sustainability in Canada’s Canola Sector1 month ago -
Canada’s canola sector is strong and growing. In 2016, Canadian canola seed and oil exports accounted for almost 15 per cent of total agriculture and food exports, valued at $9.2 billion. Canola has also been the largest crop in Canadain terms of market receipts since 2010, and accounts for more than one-fifth of all Canadian cropland. The Government of Canadaknows that research and innovation are vital to ensuring Canadian canola farmers have a sustainable and profitable future.
While visiting the Bruce D. Campbell Farm & Food Discovery Centre, Lawrence MacAulay, Minister of Agriculture and Agri-Food, announced up to $12.1 million in funding to the Canola Council of Canada under the Canadian Agricultural Partnership, AgriScience Clusters.
Building on the work of two previous clusters, this research investment includes an additional industry contribution of up to $8.1 million. The cluster will focus on advancing the growth and profitability of the sector through innovative and sustainable approaches to creating new and improved products. Activities will include adapting food processing techniques, exploring uses for canola meal in livestock production, examining practices to optimize yields, protect crops from pests, and share lessons learned with stakeholders.
“Innovation is critical to the growth of the canola industry and this research will help us to contribute to the government’s goal of $75 billion in exports by 2025,” said Jim Everson, President, Canola Council of Canada. “Not only that, it will support our strategic plan to ensure the canola industry’s continued growth, demand, stability and success – achieving 52 bushels per acre to meet global market demand of 26 million metric tonnes by 2025.”
The Government of Canada is also continuing to support new markets for the canola sector. In 2016, Canada reached an agreement to secure canola trade with China, which allows for exports of canola seeds under existing commercial terms until March, 2020. Exports of canola seed to China continue to increase reaching $2.6 billion in 2017. In addition, in June 2018 the Government introduced legislation to implement the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), which will further help to open markets and increase exports.
“We are committed to continue working closely with the canola industry, so that together we can help reach our government’s goal of $75 billion in exports by 2025,” said Lawrence MacAulay, Minister of Agriculture and Agri-Food. “The investment we announced today will help keep the sector on the cutting edge so it continues to grow sustainably while contributing to our economy and supporting well-paying middle class jobs.”
The announcement is part of Minister MacAulay’s “Growing Canadian Agriculture” tour, where he will meet with farmers, processors and industry leaders, and participate in rural agricultural events across the country, to hear ideas on how to capture new growth opportunities for the sector.
Frost Hits Canola. Do I Swath?1 month ago -
This is the question for many canola growers Sept. 4 as frost (in some areas heavy and long-lasting) hit parts of Alberta over night.
Start with these steps:
—Check standing canola the morning after a frost.
—Before taking any action, wait 4-6 hours after frost to allow the full extent of frost damage to become evident. The crop may look undamaged in the morning but by the afternoon wilting, desiccation and pod splitting may begin. This crop may need to be swathed to preserve yield, but keep in mind that high green counts are likely.
—Light to moderate frost damage may take longer to show up. If no damage is evident after the first day and you decide to leave the crop to mature more fully, scout again after 2-3 days to reassess.
—If most or all seed is mature and you planned to swath the day after a frost anyway, then don’t bother waiting 4-6 hours. Just start swathing.
Responses for heavy or light frost
Heavy frost… below -2°C: Assess the damage in early afternoon. Check pods for a white, wilted appearance. Pod shatter and pod drop could begin within a day, especially with warm sunny afternoons. If pods are desiccating rapidly, swathing right away will preserve as much yield as possible.
For canola with high seed moisture, frost in excess of -5°C is generally lethal, resulting in non-viable seed. At such low temperatures, ice crystals physically disrupt structures such as membranes and enzymes. Pods of immature canola crops frozen at lethal temperatures have been observed to turn black, whereas mild frost turns pods white or white-speckled.
Light frost… above -2°C: Hold off swathing. Check in the afternoon for wilting to make sure frost damage was not heavier than expected. You may see some speckling on the stem and pods, but this is of little concern as long as the plant is still alive. If no wilting, leave the crop standing and check daily.
What to look for during daily monitoring:
—If the majority of the seeds remain green and immature, delay swathing to allow for further seed maturity.
—If the pods are severely damaged and are beginning to desiccate, swath during periods of dew or high humidity to reduce the amount of pod shelling and pod drop.
Frost and quality. A killing frost will reduce quality, but that can’t be helped — whether you swath today or wait. Immature seeds (moisture content higher than 20%) will be damaged. Seeds with less than 20% moisture will normally escape damage. Green seed is the major downgrade that results from frost.

Plenty to Learn at November Symposium2 months ago -
The 9th Canadian Workshop on Fusarium Head Blight and 4th Canadian Wheat Symposium held in Winnipeg this fall is shaping up to be an event not only for scientists and those in the ag technology sector, but one farmers and producers will find of value as well.
“Being in Winnipeg, on the Prairies, I would love to see more producers come to this,” says Tom Fetch, event co-chair and research scientist for Agriculture and Agri-Food Canada. “I think they would find a number of things that would be helpful, [like] revolutionary ideas in technology that they could start using on their farm.”
Fetch looks after the wheat symposium side of things. Tom Gräefenhan of the Canadian Grain Commission is looking after the Fusarium head blight side of the event. Fetch said the two have been working on the event for close to a year now to get everything in order.
Each day will start with a plenary session. After that, attendees can attend any of the sessions throughout the day.
There are a total of five sessions for both wheat and fusarium head blight, running the first and second day in the afternoon. On the third day, the conference finishes at noon.
The first day will focus on breeding and genetics, with the second day focusing on the technology side of things. Day 3 will include a focus on remote sensing technology.
Steve Shirtliffe from the University of Saskatchewan will talk about drones and Heather McNairn with Agriculture and Agri-Food Canada is going to address the use of satellite images in growing wheat.
In terms of what’s new for attendees to expect, Harvey Brooks from the Saskatchewan Wheat Commission will offer a breakdown of industry funding and how that might be changing. Another highlight Fetch points out is the Grains and Health session with Yanni Papanikolaou from Nutritional Strategies Canada as the keynote speaker.
New this year is a session about wheat production and management, with a speaker from SeedMaster focusing on new technologies for producers like robotics.
The 9th Canadian Workshop on Fusarium Head Blight and 4th Canadian Wheat Symposium will be held at the Fairmont in Winnipeg, Nov. 19-22, 2018.
Registration is now open. For more information visit cwfhb-cws.com.

Canola Council Launches New Tool To Help Growers Optimize Combine Performance And Increase Yields3 months ago -
The Canola Council of Canada (CCC) released a new web-based application to help producers with combine adjustments during harvest, maximize yield and edge us closer to an average yield of 52 bu/ac by 2025.
The combine optimization tool was developed on behalf of the CCC by the Prairie Agricultural Machinery Institute (PAMI) and is intended to assist with the process of setting the combine for canola harvest. The new tool can be found at www.canolacalculator.ca alongside calculators for target plant density and seeding rates.
“In combine adjustments for all crops, we are trying to balance productivity with harvest losses and grain quality but most producers know firsthand the particular challenge this can pose for canola harvest,” says Angela Brackenreed, CCC agronomy specialist. “We often see an unacceptable level of loss that is frustrating to correct.”
In 2016, the CCC released a video explaining the loss measurement process and revamped the Combine Seed Loss Guide. Brackenreed says the combine optimization tool is a valuable follow-up. “Simply suggesting that setting adjustments need to be made when there are high losses is much easier said than done, particularly with challenging harvest conditions.”
The combine optimization tool takes the traditional diagnostic settings flowchart and puts it into a web-based application you can access on your phone. Growers can go through a stepwise process based on the harvesting issue they’re experiencing (i.e. grain loss, grain sample quality or productivity) and review the adjustment options most likely to correct the issue.
Joel McDonald, program manager of Agricultural Development Services at PAMI’s Humboldt facility points out that the optimization tool can be used for any make or model of combine. “It could be 25 years before most combines on the Prairies have built-in sensor technology that creates self-adjusting machines. Until then, there are tens of thousands of combines that rely on the operator and this guide is a new way for PAMI and CCC to reach them with the information they need when they need it.”
Angela Brackenreed and Joel McDonald will be presenting on combine grain loss and the new combine optimization tool at Ag in Motion. Catch them in the Agri-Trend Knowledge Tent on Thursday, July 19 at 2:00 pm.
The Canola Council of Canada is a full value chain organization representing canola growers, processors, life science companies and exporters.
