Tom Wolf, co-founder of Agrimetrix and Sprayers 101, models the importance of sprayer cleaning to avoid accidental application of canola-unfriendly chemicals.

Tank cleaning key to avoid Group 2 herbicide injury in canola

Agrimetrix co-founder Tom Wolf explores how a clean spray tank can curb unintentional damage in the field

It may take a concentration less than 1/250th for Group 2 herbicides to start damaging canola, according to sprayer specialist Tom Wolf. “That’s quite a dilute mixture,” he said. “You’d never think it would do anything.” Wolf was one of many presenters at Canolapalooza 2017, held in Portage la Prairie June 22.

Different varieties of blackleg resistance are put on display during Canolapalooza June 22 in Portage la Prairie.

Gene labelling tools hope to better target blackleg

Researchers say better gene classification will help match blackleg-resistant canola varieties to races of the fungus found in the field. AAFC Saskatoon has unveiled tools to quickly identify avirulence proteins (which facilitate plant infection) in submitted samples, attendees of Canolapalooza heard June 21 in Portage la Prairie.

Redbacked cutworm larvae and pupae. The pest overwinters as eggs and populations can show quite variable staging. Many will now be into their later larval stage.

Fairly average year for cutworms, flea beetles

Cutworms may be taking a bite out of your canola, but with proper planning 
they won’t eat into yields


Cutworms and flea beetles continue to affect some canola fields in the province, but experts say that while cutworm damage may be marginally lower this year than last, beetle damage may have scuttled ahead of previous years. Still, the margins are slim at best. “I think every year is a flea beetle and cutworm year,”

Apothecia are small golf tee-like structures that release the sclerotinia spores that can infect canola crops.

Decision time on sclerotinia control in canola not far off

There’s lots to consider, including the value of the crop and the disease risk

In Manitoba the potential for major canola yield losses due to sclerotinia exists every year with weather being the main driver. Farmers will soon have to decide whether to apply a prophylactic fungicide or not. “The (sclerotinia) inoculum is always there (in Manitoba) so the part of the disease triangle to consider is the environment


It was an early frost last week — likely too early to cause frost damage like this, since most of the canola was still in the ground when it hit.

Minimal frost damage on canola after mercury dips

Canola-growing regions in Manitoba will largely recover from any damage suffered 
during a mid-May period of frost, agronomists say

The third week of May was a frosty one, but so far it seems the canola crop is largely fine. Producers are reporting minimal damage after temperatures dropped below freezing across the province for several successive nights. “Certainly, at this point it’s not a big concern,” David Van Deynze, MASC vice-president of insurance operations, said.

The Canola Council of Canada says production goals and longer rotations can both happen.

Canola Council of Canada sticks to 2025 production goal

Experts are advising longer rotations for canola in the face of disease pressures, 
but the Canola Council of Canada says it won’t affect its production goals for 2025

The Canola Council of Canada says advice to lengthen rotations will not change its 2025 yield goals of 52 bushels an acre for a total 26 million tonnes. Typical wheat-canola rotation has fallen out of favour with agronomy experts, who argue that longer rotations are needed to manage disease such as blackleg, verticillium wilt or


Two online calculators are available to help you get your canola stand just right this spring.

What’s your canola-seeding rate?

New online calculators can help get this key decision just right

When it comes to putting in canola, few decisions are more important than getting the seeding rate right. Now there are two new online calculators that you can find at www.canolacalculator.ca that will help determine the correct plant stand for an individual field. The calculators determine target plant density and seeding rate, and allow farmers

Manitoba Agriculture’s John Heard says many farmers are being forced to 
adjust their fertility strategy after a tough fall.


Farmers adjust fertility plans after tough fall

There’s still plenty of opportunity to get nitrogen on if you missed the fall application window

While spring banding of fertilizer has become more popular recently, there’s still plenty of growers putting it down in the fall. That is, unless they run into a season like last year. Many farmers throughout Manitoba struggled to just get the crop off, never mind getting their fall work done. Now they’re left with the

Much of the attention focused on newcomers to Canada these days is laced with fear that they will bring change. What is often overlooked however, is that change can bring good things to a country — including economic growth. Canada’s canola story — a stunning success by any measure — is a case in point.
