Reading Time: 2 minutes Kochia is spreading through Alberta faster and further than ever expected. But how can farmers best manage the invasive weed?
Kochia spreading unexpectedly in Alberta
The invasive weed is now being spotted further north than ever before
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.
Weed seed destructors rare on Canadian farms
The devices are slowly gaining momentum in this country
Reading Time: 2 minutes Glacier FarmMedia – About 30 weed seed destructors were used last fall on farms across Canada, says an Agriculture Canada scientist. That isn’t a lot, as the country has some 50,000 grain farms that buy about 2,000 new combines every year. But adoption of the destructors, which pulverize weed seeds before they exit the combine, […] 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
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
Controlling herbicide-resistant kochia requires some different strategies
While tillage in general can harm soil health, a strategic targeted approach can help bury the seed
Reading Time: 3 minutes It’s time for a new mode of action for kochia control, but not one found in a jug of chemical. “We’ve had several years in a row of favourable conditions for kochia growth. That also can contribute to selection pressure for resistance, when herbicides are some of the primary measures that we’re using to manage […] Read more
How do you manage resistant pests?
Reading Time: < 1 minute Farmers are being asked to share their strategies on how to manage weed, insect and disease resistance. The contest offers prizes (iPads and Tim Hortons gift cards) for winning entries. “The Pest Management Challenge is an opportunity to get people talking and to encourage the adoption of resistance management best practices,” said Jennifer Hubert, an […] Read more
Wild oat a growing resistance challenge that can’t be ignored
Keep an eye on your fields this summer and be ready to tackle the problem when you see it
Reading Time: 2 minutes If you rely solely on crop protection products to fend off wild oats, you’re not going to like the eventual bottom line. Herbicide-resistant strains of the weed are going to mean you’ll eventually run out of luck. It’s not a new problem, but every year it gets just a little bit more concerning. “Resistance is […] Read more
