While you’re in the field checking canola to see if it’s ready to be cut, or perhaps already swathing or harvesting it, it’s also a good time to assess the toll disease took on your crop. Sclerotinia, blackleg and clubroot can all cause premature ripening, as disease symptoms become more obvious at the end of the season,… Read More
Boron’s complete role in plant health is not entirely understood, but the nutrient does play a key role in cell elongation, hormone response and membrane function. Boron is a micronutrient necessary for optimal yield and growth, but needed in only very small quantities. In Western Canada, trials surrounding boron have shown inconsistencies in yield response,… Read More
It should come as no surprise to insect geeks that the ash-grey insect above with a rather distracting snout is a weevil. More specifically, it’s a cabbage seedpod weevil (Ceutorhynchus obstrictus), an insect pest that has been infecting canola crops (and other Brassicaceae species) in Alberta since the mid-1990s, and it has since moved across the southern portion… Read More
As a diverse set of volunteers in the agriculture industry, it’s hard to assign a worth to the work beneficial insects accomplish, but their absence can speak volumes, if you’re listening. To showcase that, Jim Broatch, pest management specialist with Alberta Agriculture and Rural Development, talks root maggots in this Canola School, and how an insecticide application… Read More
Unless it’s too late and you’ve already found clubroot symptoms in your canola, you won’t know whether you have it without getting tested. This Canola School episode focuses on testing for clubroot and how to go about determining whether clubroot spores are present in the soil. Finding the nasty soil-borne disease when spore loads are still low… Read More
With seeding underway, it’s easy to switch the drill from cereals to canola and just continue rolling. However, Angela Brackenreed of the Canola Council of Canada has a reminder in this wet and windy Canola School episode: a clean, weed-free start to the growing season is more important than an early start. Dig into the Canola… Read More
Rotation is generally a critical part of mitigating any disease resistance problem. When it comes to preventing the breakdown of resistance in blackleg-resistant canola varieties, the first line of defence is an extended crop rotation with non-host crops. Beyond that, growers can also rotate the canola varieties they’re growing, suggests Anastasia Kubinec, oilseed specialist with Manitoba Agriculture,… Read More
Brassicogethes aeneus, commonly referred to as the pollen beetle and formerly known as Meligethes aeneus, is a major pest of canola in countries like Scandinavia, and, is now present in eastern Canada. And, though they are not yet a problem in western Canada, entomologists are suggesting we become familiar with what to look for. “One nice thing… Read More
With findings of clubroot disease in parts of Western Canada where it has not been a problem before, at what point should a farmer in these new clubroot areas switch to growing clubroot-resistant canola varieties? To make that decision, you must first assess and prioritize the risks to your canola, suggests Anastasia Kubinec, oilseed specialist with Manitoba Agriculture, in this Canola… Read More
It’s too early to say how big a problem verticillium wilt could become for the Canadian canola industry, but it should be on the radar for growers, says the crop pathologist taking the lead on the new disease issue within Manitoba Agriculture. As reported by Real Ag last week, the first known case of Verticillium… Read More
“Neonicotinoids,” “Colony Collapse Disorder,” “Varroa,” “Nosema”… Defining those colloquialisms (and others) was just one of the goals the Canola Council of Canada’s Gregory Sekulic had in mind when he presented “Buzzwords about Bees” at the Farming Smarter Conference in Medicine Hat. Sekulic wanted to clear the air on jargon that so often exacerbates misunderstanding “We really lose… Read More
With clubroot disease showing up in fields east of Alberta over the last few years, there’s work underway in Manitoba to survey the entire canola-growing region of the province for the presence of clubroot spores. So far, spores or symptoms have been found in 13 fields in 10 rural municipalities in Manitoba. Spore concentrations in… Read More
One of the leading causes of herbicide injury in canola is insufficient sprayer cleaning, says Clark Brenzil, provincial weed control specialist for the Saskatchewan Ministry of Agriculture. Whether due to drift or residue, herbicide injury can result in drastic yield losses, besides being an eye-sore to drive by. Related: Spray Tips with Tom Wolf — Ep. 6: 7 Steps to… Read More
Now that there’s a little more time on our hands, we can look back at the growing season and see where issues and inefficiencies arose. One of the major concerns this year in Western Canada was herbicide injury, especially in canola crops, where some growers thought their Liberty Link canola was seeing injury from its… Read More
With canola swathing underway across Western Canada, now is the time for growers to assess the toll that diseases have taken on the crop. The “what to look for” list at this time includes the main suspects: blackleg, sclerotinia and clubroot. In this episode of the Canola School, Keith Gabert of the Canola Council of… Read More
