Herbicide resistance flirts with crisis mode

Although not one-size-fits-all, integrated weed management may come to the rescue

By
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

Moving from dry to wet

Improved moisture conditions can mean different strategies

By
Farmers in Western Canada can breathe easy. Rains across most of the Prairies this spring have gone a long way toward recharging groundwater levels and lowering the risk of drought across the region. “We had an extremely warm winter with lower-than-normal precipitation in most areas,” says Trevor Hadwen, agroclimate specialist for Agriculture and Agri-Food Canada.

Kochia tumbling into Prairie pulse crops

Scouting — and testing for herbicide resistance — will be important this spring

By
Glacier FarmMedia — Concerns about the spread of kochia are growing for Saskatchewan’s pulse producers. Michael Brown, agronomy manager for Saskatchewan Pulse Growers, and Martin Carr, agronomy manager for WinField United, have seen the pesky tumbleweed spread throughout Saskatchewan, Alberta and the United States. The weed is resistant to some herbicides, among them Groups 4, […] Read more

Into the weeds: 2024 in preview

Prairie specialists consider which weeds are most likely to succeed as the season proceeds

By
The past few seasons have been a challenging time for farmers on the Canadian Prairies. Extreme heat, lack of precipitation and steep increases in production costs have caused some sleepless nights for many producers. As if those weren’t enough to contend with, another potential threat to crops will soon rear its ugly head: weeds. Grainews […] Read more

Garden seeds lead to problem weeds

The names in the garden catalogues may sound pretty, but the plants are far from that in pastures or fields

By
Glacier FarmMedia — Manitoba rancher Herman Bouw was casually perusing a gardening seed catalogue when a particular ornamental grass item caught his eye. The plant was listed as “squirrel tail grass,” but Bouw thought it looked awfully similar to a species with a more cursed name on the Prairies. A comparison of scientific names confirmed […] Read more

Weed alerts on the southern front

A North Dakota weed expert cautions Prairie farmers about kochia, waterhemp and Palmer amaranth and their evolving herbicide tolerances

By
Of all the things shared by Prairie farmers on both sides of the Canada-U.S. border, an abiding love of their land, fretting over the weather and a no-nonsense, ‘get ‘er done’ attitude are among those that come to mind. Unfortunately, this also includes weed problems. Weeds know no borders, of course, so when weed trouble […] Read more
A recent study conducted by Agriculture and Agri-Food Canada on the use of weed seed control technology at harvest was the first such project to be conducted in Canada.

Weed-fighting tool gets a closer look

A recent AAFC study looked at the effectiveness of harvest weed seed control technology

By
Mechanical weed seed control at harvest has been around for a while in Australia, but it’s a relatively new technology in Canada and adoption rates remain comparatively low. A recent study conducted in Western Canada looked at the efficacy of that technology and the role it could play in alternative weed control strategies as concerns […] Read more

Pre-spraying boosts effectiveness of electric weed-killing machine

Crop.zone has partnered with John Deere on a new, wider machine for in-crop weed control

By ,
Glacier FarmMedia — German company tested its electric desiccation system on Canadian farms this growing season, as it works to bring weed control through electricity to large-scale operations. Crop.zone is unique in that it combines an application of liquid to the plant at the front of the tractor, and an electric shock at the back, […] Read more

Herbicide is only part of the pasture weed control program

Proper grazing management doesn't give weeds a place to start

By
Western Canadian livestock producers looking to control weeds on pasture should consider an integrated pasture management program that uses several tools from the tool box, says a specialties business leader with Corteva Agriscience. Mark Versluys says applying a herbicide to knock back some of the more difficult weeds is an excellent start, but that needs […] Read more
