Producer Steve Snider manages weeds the mechanical way, using mow tilling (pictured), harrowing, and plowing to tackle tough weeds like Canada thistle.

Three ways to manage tough weeds on organic farms

Using green manure, increasing seeding rates, and incorporating mechanical weed control can help organic producers manage weeds on their operations

Reading Time: 3 minutes The biggest challenge on Steve Snider’s organic farm is weeds — and killing them properly isn’t a one-size-fits-all operation. “The key to remember in organics is there’s no one answer,” said Snider, who has been growing organic grain on his farm near Edberg for 30 years. “It’s not like conventional agriculture. You can’t control weeds […] Read more

Herbicide resistance becoming the new reality in Alberta, says weed expert

Researchers in Lacombe are investigating mechanical ways to deal with resistant weeds, but there’s no ‘silver bullet’

Reading Time: 3 minutes Some Alberta farmers are in denial about weed resistance — and they’re in for a rude awakening, says a federal weed scientist. “We spend over $12 an acre on average, and about $500 million a year on wild oat control alone (on the Canadian Prairies),” said Neil Harker. “That’s the weed we put the most […] Read more

The basics of combating resistant weeds are simple — rotate herbicides by group; scout; employ good sanitation methods and diverse rotations, said Hugh Beckie.

Herbicide resistance is everywhere you look

This year it’s Alberta’s turn to be surveyed by Ag Canada — but researchers already know the news won’t be good

Reading Time: 3 minutes If you’ve found herbicide-tolerant weeds in your field, you’re not in the minority. Weed resistance is increasing worldwide, so it’s really important that Prairie growers understand growing herbicide tolerance, says one of the country’s top resistance experts. “Group 2 really overshadows all the other groups in terms of weed resistance,” said Hugh Beckie, a research […] Read more

This is not what you want to see — resistant kochia was thriving in this wheat field in southern Saskatchewan in 2015.

This is not good — triple-resistant kochia has entered Alberta

Glyphosate-resistant kochia was bad but there’s a new strain that’s much worse

Reading Time: 3 minutes Kochia, one of Western Canada’s most abundant and economically devastating weed species, has won another major battle in overcoming herbicide. This summer, the first known Group 4 herbicide-resistant kochia was identified in a durum wheat field in southwestern Saskatchewan. And samples currently being tested from a farm in southern Alberta are also suspected to be […] Read more

Controlling winter weeds now will pay off later

It’s cheaper to control winter weeds in the fall, and they won’t compete with your spring crop

Reading Time: 2 minutes You’ve been busting your butt during harvest and you’ve scouted your field many times during the growing season. But if you’re direct seeding, it’s worth scouting just one more time for winter weeds after you harvest. “It depends on what kind of production system a producer has,” said Mark Cutts, crop specialist with Alberta Agriculture’s […] Read more
