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 Mark Halsall March 21, 2024

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

US court cancels approvals for widely used dicamba weedkillers

EPA violated procedures mandating public input, judge rules

By Reuters, Tom Polansek, GFM Network News February 7, 2024

A U.S. court has nullified the government's latest approvals of certain agricultural weedkillers sold by Bayer, BASF and Syngenta, fueling uncertainty among farmers who spray the products on soybeans and cotton genetically engineered to resist them.

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 Jim Timlick January 25, 2024

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

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

By Glacier FarmMedia, John Greig January 25, 2024

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

Cover crops: enough already

The benefits are often 'blown up' while the challenges are understated

By Les Henry January 2, 2024

Cover crops is a topic with a lot of ink spilled in many farm publications in recent years. Some scribblers seem to imply that a farmer is a laggard and an environmental hazard if she/he is not using cover crops on a regular basis. Cover crops actually include a wide variety of cropping sequences, and […] Read more

Agritechnica update: Give a big shock to weeds

By Glacier FarmMedia, GFM Network News November 15, 2023

Farmers are being pushed to find an alternative to desiccants to burn down crops, as companies are increasingly leery of herbicides approved close to harvest. People have been shocking weeds with electricity for 100 years, but the return on the electricity invested and the technology required to do so safely haven’t always worked. Crop.zone is […] Read more

Applying management to pasture weed control

Maintaining a healthy forage stand is best defence against weeds

By Lee Hart September 28, 2023

Peter Tokar and Jacques Saquet are two Manitoba livestock producers who have applied changes in management practices to help control some particularly difficult pasture weed infestations. Tokar, who owns a mixed farm — primarily a beef cow-calf operation — near Swan River in west-central Manitoba, deals with patches of burdock on his pastures. Saquet, who […] Read more

Palmer amaranth pops back up in Ontario

Weed infamous in U.S. for multiple herbicide resistances

By Dave Bedard, GFM Network News August 29, 2023

A single plant that showed up this summer on the edge of a southwestern Ontario cornfield is cause for concern among Canadian farmers, weed specialists warn. Writing Monday in the ag ministry’s Field Crop News, Ontario provincial weed management specialist Mike Cowbrough said the plant in question, found in Wellington County, is confirmed as palmer […] Read more

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'

By GFM Network News July 20, 2023

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

'You’re not going to spray your way out of this'

By GFM Network News July 18, 2023

It’s a relatively new solution to the age-old problem of trying to get rid of weeds without broadcasting the seed or using increasingly less effective herbicides — mechanical separation and pulverization of weed seed. Harvest weed seed control might not be a golden bullet to tackle glyphosate-, fluroxypyr- and dicamba-resistant weeds, but according to Agriculture […] Read more
