AAFC’s Breanne Tidemann says kochia (seen here) appears to be spreading to areas of Alberta where it wasn’t seen previously.

Into the weeds: 2024 in preview

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

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

Glacier FarmMedia — Manitoba rancher Herman Bouw was casually perusing a gardening seed catalogue when a particular ornamental grass item caught his eye.

A comparison of scientific names confirmed […] Read more


Planting perennial forages in ditches is recommended to help keep kochia from getting a toehold.

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

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

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

Vietnam to call off thistle seed ban in grain imports

Move will restore regular grain trade, Cereals Canada says

Vietnam is expected to resume nearer-to-normal grain trade with exporting nations such as Canada, after it loosens a significant restriction on weed seed content.

At Ag in Motion: Herbicide resistance fight needs integrated seed management

'Those seedlings we don’t manage to kill (are) probably the most herbicide-resistant'

Harvest weed-seed control takes aim at reducing herbicide-resistant weeds that western Canadian farmers find more and more every year. At the Ag in Motion outdoor farm show this week, field residue management manufacturer Redekop won the Innovations Award for Environmental Sustainability for its harvest Seed Control Unit, which destroys more than 95 per cent of […] Read more
