Beating herbicide-resistant weed populations means making a plan with clear goals and objectives and staying on top of it — and that means not allowing weeds any opportunity to set seed in big numbers.

Farm gets aggressive on wall-to-wall resistant wild oats
Agronomist says managing herbicide-resistant weeds is like starting a fitness routine: make a plan, set goals, stick with it
How farmers can help map, monitor and forecast pest outbreaks
Researchers can help producers develop pest management plans — but farmers’ help is needed to know which pests are where, and how many
Prairie scientists conducting research into field crop pests can always use more help from producers — whether it’s by granting access to farmland, or just by reporting what they see in the field.
New Group 14 tank mix partner may be on horizon
A Japanese firm’s new chemical isn’t like the other PPO inhibitors
Not yet registered in either Canada or the U.S., the Japanese active ingredient-in-waiting could be needed sooner than later, because many growers in Saskatchewan and Alberta are struggling with herbicide-resistant kochia.
Kochia’s expanding herbicide resistance puts pressure on no-till systems
Kochia populations in Saskatchewan and North Dakota are now resistant to group 14 herbicides, leaving fewer options for Prairie farmers
Based on preliminary data from a recent Prairie-wide kochia survey, AAFC’s Charles Geddes suspects Group 14-resistant kochia is now present in multiple fields in Saskatchewan and expects it could soon be confirmed in other regions as well.
New Bayer genetics to open up soybean herbicide tolerance
Bayer’s Vyconic genetics to be integrated with the company’s soybean varieties in coming years
If all goes according to plan, by 2027 soybean farmers throughout Canada will have new soybean varieties with tolerance to five key herbicides. Bayer Crop Science Canada on Monday announced its Vyconic soybean trait set, calling it “a leap forward in weed control, enabling farmers to manage their fields with unparalleled flexibility.” Vyconic features tolerance […] Read more
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
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
