New Bayer genetics to open up soybean herbicide tolerance
Vyconic trait set offers tolerance to five herbicides and will be integrated with the company’s soybean varieties in coming years
Bayer’s Vyconic soybeans offer tolerance to five herbicides, a first for Canadian crop growers. This new advancement could help farmers combat resistant weeds and manage fields.
Why herbicide effectiveness varies
Peter Sikkema discusses how to hedge your bets when controlling weeds
Herbicides are incredible weed control tools, but their effectiveness can be significantly degraded by a variety of environmental, human and other factors.
Bayer looks to AI to combat herbicide resistance faster
Bayer's Icafolin will be its first new mode of action herbicide in some 30 years when it launches in 2028
Weeds are growing resistant to the herbicides already on the market, and agribusiness companies like Bayer are in a desperate search for new modes of action to help farmers kill them.
Waterhemp is the new “oh-no” weed
Ontario biotypes are resistant to up to five different herbicide groups
It’s no longer a matter of ‘if’ waterhemp comes to your farm, it’s ‘when.’ Those were the words of Richard Anderson, a business representative with BASF, speaking last month at the Southwest Agricultural Conference at University of Guelph’s Ridgetown Campus. It was probably the most pertinent take-home message from a panel discussion on tackling waterhemp, […] Read more
Crop-killing weeds advance across US farmland as chemicals lose effectiveness
Losing battle with weeds adds pressures to farmers already stressed by inflation, extreme weather
Crop-killing weeds such as kochia are advancing across the U.S. northern plains and Midwest, in the latest sign that weeds are developing resistance to chemicals faster than companies including Bayer BAYGn.DE and Corteva CTVA.N can develop new ones to fight them.
Palmer amaranth pops back up in Ontario
Weed infamous in U.S. for multiple herbicide resistances
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
Herbicide resistance fight requires integrated seed management
‘You’re not going to spray your way out of this’
Seed control at harvest is not a golden ticket to tackle weeds resistant to glyphosate, fluroxypyr and dicamba, but it’s among a range of solutions needed to stem the tide, says Agriculture and Agri-Food Canada researcher Breanne Tidemann. “You’re not going to spray your way out of this,” she said about herbicide resistance during her […] 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'
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'
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
