A U.S. propane industry group is touting the concept of injecting steam into soil to kill weed seeds, but other research shows difficulties in heating soil to a high enough temperature to kill weed seeds with a mobile implement.

Using steam as a weed control alternative to chemicals
Two application methods highlight efficacy rates and cost differences
What would happen if Roundup disappeared?
Bayer hints it might stop selling Roundup due to legal problems. What could it mean for farmers?
As Bayer hints it may soon exit the glyphosate business, the once-hypothetical scenario of farming without Roundup is suddenly on the table.
Get your kochia under control — by burying it
An AAFC scientist found covering kochia with chaff was the most effective at killing it
For the last few years, AAFC scientists in Saskatoon have been studying methods to “artificially” bury kochia seeds in the soil as a possible way to control the tumbleweed.
A Saskatchewan farmer is combining weed control with harvest
The Seed Terminator, an attachment that destroys weed seeds on their way out of the combine, is being put to work on a farm north of Saskatoon
Josh Lade’s farm is all-in on a combine attachment called the Seed Terminator, on which he’s spent mid-six figures over the past seven years, making sure it’s put to work on every acre controlling what he calls “the fittest weeds of the year.”
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
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
What the weed seed smasher survey says
Farmers share insights from working with weed seed control technology
A recent study conducted by Agriculture and Agri-Food Canada provides a glimpse into why some Canadian producers are using harvest weed seed control, the effectiveness of the technology and some of the challenges associated with it. The 49-question online survey was conducted between the spring and fall of 2023. A total of 10 producers from […] Read more
Wake weeds up and let Mother Nature sort them out
Researcher finds value in wood vinegar in unique weed-killing process
Glacier FarmMedia — It makes some intuitive sense: stimulate weeds’ growth at the wrong time of the year and let the winter frost kill them off. The challenge, says a scientist, is finding the right stimulant to wake them up. Shaun Sharpe, a weed researcher with Agriculture and Agri-Food Canada (AAFC) in Saskatoon, may have […] 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
Redekop partnering on new system for weed seed destruction
Canadian manufacturer's work with U.S. company allows for light technology to destroy weed seeds
One way to defeat the problem of weed resistance is to keep as many weed seeds out of a field as possible. Redekop’s Seed Control Unit (SCU), which pulverizes seeds coming out of the back of a combine, is one tool to help do that. But it can only be used on Class 8 and […] Read more
