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

At Ag in Motion: Harvest weed control still in the mix

'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

Timing of post-harvest spray applications is an important factor to consider. For example, some perennial weeds like Canada thistle require four to six weeks to regrow for a post-harvest herbicide application to be effective, which can be difficult in areas that receive early snowfalls.

Tips and strategies for pre- and post-harvest weed control

While in-field scouting tops the list, also consider post-spray followups, detailed record keeping, weed assessments, water quality and more

By Jim Timlick June 8, 2023

Sometimes the simplest solutions are the best ones. Breanne Tidemann, an Alberta-based researcher with Agriculture and Agri-Food Canada (AAFC), says boots on the ground remains one of the most effective strategies when it comes to weed control. “Don’t rely, especially in the spring, on the 80-kilometre-per-hour drive-by. Get out and get those boots on the […] Read more

Pre-harvest aids

Know why you apply: tips for assessing the need for pre-harvest aids

By Mark Halsall August 15, 2022

Canola can be a challenge to harvest if stands are too thin or too weedy or if there’s uneven ripening due to crop stage differences. Green stalks and weeds not only hinder harvest but can cause problems in storage too. In situations like these, many Prairie farmers opt to use pre-harvest aids as a late-season […] Read more
