Rethinking weed management

Not every weapon against herbicide resistance comes out of a sprayer

Farmers up against herbicide-resistant weeds need to rethink their cropping systems and add more angles in their approach to long-term weed control. This advice came from Dr. Drew Lyon of Washington State University during his presentation at the Manitoba Agronomists’ Conference in December. While Lyon’s discussion primarily focused on integrated weed management (IWM) in dryland […] Read more

Herbicide researchers pick new fights

Different modes of action may overcome a lull in herbicide discovery

Herbicide development has slowed in recent years, but innovative research methods could soon drive significant progress in the field. For decades, the pace of discovery of new modes of action — that is, how a herbicide interferes with the plant’s normal functions — was robust. From the 1950s through the 1980s, an average of one […] Read more


Boom stability, boom height and travel speed are critical to uniform herbicide application and curbing variability in spray coverage.

Tackling herbicide resistance with smarter spraying

Tom Wolf from Sprayers101.com shares insights on how spraying techniques and technologies can help farmers stay ahead of resistance

With herbicide resistance on the rise, farmers can no longer spray their way out of weed problems — but smarter spraying can help prevent making resistance worse. That was the message from spray application specialist Tom Wolf, who spoke recently at the Manitoba Agronomists’ Conference. Wolf, from Saskatoon, is known for his contributions to Sprayers101.com, […] Read more

The evolving fight against volunteer canola 

As its prevalence grows, farmers are adopting integrated strategies to manage one of the Prairies' most persistent weeds

While chemistries out there continue to work for most farmers, the days of spraying their way out of volunteer canola issues are receding in the rearview mirror.  “I’m not going to say that herbicides don’t work because there are quite a few herbicide options still to manage volunteer canola,” says Charles Geddes, a research scientist […] Read more

Herbicide combo launched against resistance in wild oats

Product features a dual mode of action with Group 1 and Group 2, meant to remove guesswork from weed control

Glacier FarmMedia – Wild oats and kochia are the most problematic weeds in Western Canada. They’re everywhere, and often come with resistance to herbicides. “The story behind wild oat being one of the biggest grassy weed issues and kochia being one of the biggest broadleaf weed issues, is generally consistent across the board for the […] Read more

Maul of the wild

Farmers who missed two-decade-old advice on wild oat management now face the fallout, but new research and technology might still turn the tide

Any Prairie farmers who ignored a 2005 paper on managing herbicide-resistant wild oats, back when it first dropped, might feel like they’re getting an “I told you so” finger wag if they were to read it today. Authored by Hugh Beckie, a former AAFC researcher known for his contributions to weed management and herbicide resistance […] Read more


Ryan Ruchkall uses a drone to collect field data on kochia and wild oat at EMILI’s Innovation Farms. EMILI is working with Geco Engineering to assess the performance of Geco’s weed mapping technology for predicting weed locations and detecting emerging herbicide resistance.

Integrated weed management faces new future

Intercropping, predictive weed control could redraw battle lines in the fight against herbicide-resistant weeds

Glacier FarmMedia — Herbicide resistance in weeds is rising and there are no new chemistries on the horizon, so farmers will need fresh approaches to integrated weed management strategies. “I think the best management practice that someone could do for weed resistance is the one you’re not currently doing on your farm,” says Rory Cranston, […] Read more

VIDEO: Herbicide alternatives to glyphosate studied

With glyphosate coming up against weed resistance – and outright bans as a herbicide in some countries – there’s likely a time on the horizon where it won’t be a crop grower’s ‘go-to’ herbicide for weed control. So, what other herbicide options are on the market that could help fill the gap? At this year’s […] Read more

Herbicide resistance flirts with crisis mode

Although not one-size-fits-all, integrated weed management may come to the rescue

They’re big numbers underscoring a big problem. In Saskatchewan, over 15 million acres of weed patches are resistant to Groups 1 and 2 herbicides. Of 31 known herbicide sites of action, 21 have confirmed resistance to a weed species. And, with 56 confirmed cases, Canada is third in the world for herbicide-resistant weeds. These are […] Read more
