Think beyond the herbicide jug when dealing with wild oats
With no new chemistries on the horizon, Prairie farmers will need to focus on cultural control
Glufosinate-resistant waterhemp appears in U.S. Midwest
Signs of such resistance are also developing in kochia, a U.S. weed scientist warns
News of glufosinate-resistant kochia in the U.S. is concerning as farmers are losing options to control waterhemp, also of the pigweed family.
Farm gets aggressive on wall-to-wall resistant wild oats
Agronomist says managing herbicide-resistant weeds is like starting a fitness routine: make a plan, set goals, stick with it
Beating herbicide-resistant weed populations means making a plan with clear goals and objectives and staying on top of it — and that means not allowing weeds any opportunity to set seed in big numbers.
Rethinking weed management
Not every weapon against herbicide resistance comes out of a sprayer
Farmers up against herbicide-resistant weeds need to rethink their cropping systems and add more angles in their approach to long-term weed control. This advice came from Dr. Drew Lyon of Washington State University during his presentation at the Manitoba Agronomists’ Conference in December. While Lyon’s discussion primarily focused on integrated weed management (IWM) in dryland […] Read more
Maul of the wild
Farmers who missed two-decade-old advice on wild oat management now face the fallout, but new research and technology might still turn the tide
Any Prairie farmers who ignored a 2005 paper on managing herbicide-resistant wild oats, back when it first dropped, might feel like they’re getting an “I told you so” finger wag if they were to read it today. Authored by Hugh Beckie, a former AAFC researcher known for his contributions to weed management and herbicide resistance […] Read more
Integrated weed management faces new future
Intercropping, predictive weed control could redraw battle lines in the fight against herbicide-resistant weeds
Glacier FarmMedia — Herbicide resistance in weeds is rising and there are no new chemistries on the horizon, so farmers will need fresh approaches to integrated weed management strategies. “I think the best management practice that someone could do for weed resistance is the one you’re not currently doing on your farm,” says Rory Cranston, […] Read more
Into the weeds: 2024 in preview
Prairie specialists consider which weeds are most likely to succeed as the season proceeds
The past few seasons have been a challenging time for farmers on the Canadian Prairies. Extreme heat, lack of precipitation and steep increases in production costs have caused some sleepless nights for many producers. As if those weren’t enough to contend with, another potential threat to crops will soon rear its ugly head: weeds. Grainews […] Read more
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
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
Herbicide-resistant weed update for Saskatchewan
Your biggest herbicide-resistant weed threats for 2023 based on the latest survey results
As any farmer will attest to, herbicide-resistant weeds are a growing concern on the Canadian Prairies. In fact, it’s estimated they cost farmers in Western Canada as much as $530 million annually in lost yields and alternative weed management practices. Charles Geddes, a research scientist with Agriculture and Agri-Food Canada (AAFC), who specializes in weed […] Read more
Take an integrated management approach on problem weeds
Q & A with an expert
Q: A dead weed is a good weed, so how do we better control and kill weeds in our crops? A: Implementing an integrated pest management strategy that incorporates best practices will help manage weeds. Pesticide use in agriculture allows us to grow more food, but it’s not a bulletproof solution to weed management. The […] Read more
