Each July canola growers are faced with the difficult question, "Should I or shouldn't I spray for sclerotinia?" In the more humid parts of Western Canada, sclerotinia is a huge yield robber. It usually strikes on the years when the canola crop has its greatest yield potential, but spraying is expensive and proper timing can... Read More

Relatively few cases of clubroot have been confirmed in Saskatchewan, but with many documented cases just to the west in Alberta an obvious question emerges – has Saskatchewan been good or has it been lucky? In this episode of Real Agriculture's Canola School, Errin Willenborg, research director with SaskCanola, discusses the status of the clubroot... Read More

Seeding rates are always a hot topic, and for good reason. The only thing more expensive than buying and planting too much canola seed is not having enough seed in the ground and losing yield potential. Canola Council of Canada agronomist Ian Epp is often asked, "Can I lower my seeding rate?" as farmers are... Read More

The average size of a new grain bin in Western Canada has grown dramatically in recent years. 1,650 bushel flat-bottom bins, while still needed in some cases, are turning into relics of the past. "Right now, the average bin going up is around 25,000 bushels," says Lorne Grieger of the Prairie Agricultural Machinery Institute (PAMI),... Read More

Not only do dry soil conditions hamper seed germination, they also raise the risk of fertilizer toxicity for seedlings after they germinate, especially in a sensitive crop like canola. That means rates of fertilizer placed at seeding last year or the year before might not be safe this year, explains Don Flaten, soil scientist at... Read More

When a field is confirmed infected with clubroot, it's recommended that producers implement (or continue) strict sanitation protocols, crop rotations, and the responsible use of Plasmodiophora brassicae-resistant canola varieties. There may be further options, however, like the use of fumigants traditionally used in horticulture. "The first fumigant I look at is Vapam, and the Vapam... Read More

With increasing cases of herbicide resistance, machines designed to destroy weed seeds at harvest could be a valuable tool. But like any technology that is not yet widely adopted, there are also some lessons to be learned and challenges to overcome, as researchers with Agriculture and Agri-Food Canada confirmed last year. 2017 marked the first...

Although it's been proven that high pH soil will not stop the spread of clubroot disease, liming has been used as a tool to curb the disease in other parts of the world. Early results from a research project underway in Alberta show raising the pH of acidic fields with lime could potentially aid in... Read More

Seven years after swede midge was identified in Ontario, three adult midge were found in Saskatchewan, in 2007. It was then believed the insects were the same species (Contarinia nasturtii), but researchers have since discovered differences between the two. "We have now behavioural evidence — we know that what we thought was swede midge in... Read More

Researchers with Agriculture and Agri-Food Canada at Saskatoon have developed a lab test for identifying blackleg disease races in canola that complements the new blackleg resistance-gene labels on canola seed. Knowing both factors — the blackleg races present in a field and the disease packages available in seed — will allow farmers to select varieties... Read More
