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.
Cancer agency reclassifies another herbicide ‘probably carcinogenic’
Syngenta says IARC’s report shows no ‘causal link’ between atrazine and cancer
The WHO’s cancer research agency has now put atrazine, a herbicide well known to corn growers, in the same potential-hazard category where the agency put glyphosate.
A rancher’s ‘bitin’ list’
A Little Bit Western: Invasive weeds, gophers, grasshoppers and raccoons are all on this rancher’s naughty list
This Saskatchewan rancher comes up with her ‘bitin’ list,’ channeling her inner Tyler Childers.
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.
Using steam as a weed control alternative to chemicals
Two application methods highlight efficacy rates and cost differences
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.
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.
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.
Grow forages, starve weeds
Forages disrupt weed routines and slow herbicide resistance — if you can use them
“Forages actually can be used to combat resistant weeds,” Kim Brown says. “A perennial forage stand will last for several years, but in a spring annual crop rotation, you’re dealing almost exclusively with annual crops most of the time.”
