News of glufosinate-resistant kochia in the U.S. is concerning as farmers are losing options to control waterhemp, also of the pigweed family.

Glufosinate-resistant waterhemp appears in U.S. Midwest
Signs of such resistance are also developing in kochia, a U.S. weed scientist warns
Geco, Gowan team up on predictive weed control using multi-year imagery
AI tools forecast patch-prone zones so farms can adjust treatments before weeds emerge
A new partnership between Geco and Gowan brings predictive weed mapping to more Prairie farms, using multi-year imagery to forecast patch-prone zones and support targeted herbicide plans.
FMC rolls out new burnoff herbicide combo for cereal growers
Avireo pairs up a Group 27 herbicide with a Group 14
FMC Canada has launched Avireo, a unique co-pack combination in the pre-seeding and pre-emergence burnoff market for use by wheat, durum and barley growers in the four western provinces.
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
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.
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
