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
Reading Time: 4 minutes 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
Reading Time: 3 minutes 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

Ag input firm FMC’s shares tumble after lowering financial targets

Partners 'rapidly reduced inventory levels'

By
Reading Time: < 1 minute Reuters — Shares of FMC Corp. fell more than eight per cent on Monday after the agricultural products supplier cut its outlook for the year on volume declines in most of its major markets. “Towards the end of May, we experienced unforeseen and unprecedented volume declines in three out of our four operating regions, as […] 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
Reading Time: 6 minutes Glacier FarmMedia – 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 […] Read more

Court cites lack of analysis of effects on wildlife

By
Reading Time: 2 minutes Paris | Reuters — A French court has banned the sale of two glyphosate-based herbicides produced by Swiss chemical group Syngenta because of a lack of analysis on the chemical’s potential harm to some wildlife. “The decision on Sept. 30, 2020 by French health security agency ANSES to renew the marketing authorization for the chemical […] Read more

The one-two weed punch farmers are up against

Managing Canada fleabane and waterhemp is an ongoing challenge for IP and Roundup Ready soybean growers

By
Reading Time: 4 minutes The invasion continues. From 2010 to 2015, glyphosate-resistant Canada fleabane spread from Windsor to the Quebec border — more than 800 kilometres in just six years. Along the way, it evolved resistance to Groups 2 and 9 modes of action. Waterhemp has also spread rapidly, with biotypes resistant to Groups 2, 4, 9, 14 and […] Read more

When less is more in weed control

A study shows that soybean yields decline as soil nitrogen increases

By
Reading Time: 5 minutes We all know that canola likes a good shot of nitrogen. Unfortunately, that includes canola volunteers, and a study says you may be better off to starve them and let your soybeans compete on their own.

Is the end of the chemical era drawing near for farms?

The future of weed control is going to require a more balanced approach

By
Reading Time: 6 minutes Glacier FarmMedia – Chemical herbicides have long been the jewel in the crown of weed management, but after seven decades of use, natural selection is turning back the calendar. Herbicide resistance in weeds was first discovered in the 1980s and the problem has steadily increased. With no new chemistries introduced in more than 30 years, […] Read more
