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
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
Face herbicide-resistant wild oats head on, say producers
New video gives the view of three Prairie farmers who have been hit by resistant weeds and battled back
Reading Time: 4 minutes Don’t turn a blind eye: Admit you’ve got a problem and get on top of it right away. The issue is herbicide-resistant wild oats and that’s the advice from a trio of Prairie producers in a new video from the Resistant Wild Oat Action Committee. “It’s definitely something that it pays to get on sooner […] Read more
Group fighting resistant wild oat has new resources for producers
The threat is already serious and poised to get much worse without concerted management efforts
Reading Time: 2 minutes When it comes to herbicide-resistant wild oat, the odds favour the bad guy. “The last herbicide-resistance survey (Beckie et al. 2020) indicates that 69 per cent of wild oat fields have herbicide resistance,” Alberta Wheat agronomy research extension specialist Jeremy Boychyn noted in an article in May. “Additionally, 62 per cent of those fields are […] Read more
The lowdown on wild oat resistance
Reading Time: < 1 minute Currently, 69 per cent of wild oats on the Prairies have some type of herbicide resistance, and there are limited control options if the weed has developed both Group 1 and 2 resistance. In light of this, the Resistant Wild Oat Action Committee is working to develop increased awareness, beginning with a series of infographics. […] Read more
Glyphosate-resistant wild oats are in Australia, and that’s bad news here
Aussies usually see resistance first, with Canada close behind – and that means a ‘scary’ scenario for Prairie farmers
Reading Time: 5 minutes Glyphosate-resistant wild oats have been found in Australia and that should be a wake-up call to any farmer who thinks it couldn’t happen in Canada. “This is the first confirmed case of glyphosate-resistant wild oats in the world,” said federal research scientist Breanne Tidemann. “It’s something we’ve been concerned about but no one has ever […] Read more
Millions of Alberta acres have resistant weeds
Kochia and wild oats top a long list of resistant weeds that are now present in Alberta, says crop specialist
Reading Time: 2 minutes When it comes to herbicide resistance, producers should be looking for trouble. The ongoing spread of resistant weeds means producers should be actively scouting for it, said provincial crop specialist Harry Brook. “We now have glyphosate resistance in kochia in southern Alberta and it continues to spread,” said Brook. “These should serve as a wake-up […] Read more
Saskatchewan herbicide resistance a heads-up for Alberta
More than half of fields surveyed had a resistant weed, with Group 1-resistant wild oat at the top of the list
Reading Time: 3 minutes Alberta’s herbicide-resistant weed survey is underway this summer, but the results from Saskatchewan paint a grim picture of what to expect here. “Since 2009, there’s been an 89 per cent increase in the land area affected by herbicide-resistant weeds,” said federal research scientist Breanne Tidemann. “We are in a fairly steep incline in terms of […] Read more
Half of Alberta fields have herbicide-resistant wild oats
The short-term gain from growing profitable crops too frequently will bring long-term pain, say weed experts
Reading Time: 4 minutes For Craig Shaw, herbicide resistance is a wreck waiting to happen. “It’s manageable at the present moment, but I wouldn’t guarantee it will remain manageable moving forward,” said Shaw, who has widespread herbicide resistance on his farm near Lacombe. “We’ve learned our lesson in terms of staying on top of weed control and making sure […] Read more
Brace yourself — winter annual weeds worse than usual this year
Dry conditions earlier this spring gave winter annuals an edge and for some growers, it’s too late to manage them
Reading Time: 2 minutes The dry conditions of early spring could lead to a spike in winter annual weeds. “Winter annuals could be a problem,” said Neil Harker, research scientist with Agriculture and Agri-Food Canada. “We really haven’t had a lot of spring moisture, so the ones that were already established, like stinkweed and flixweed and winter annual cleavers, […] Read more
Winter cereals match herbicides in controlling wild oats
Producers might be ‘fairly shocked,’ but study finds winter cereals are as effective as herbicides in wild oats control
Reading Time: 2 minutes Winter cereals control wild oats just as well as herbicides do, suggests a study underway in Lacombe. “When we had two years of winter cereals — either running or with an early-cut silage in between — we had as good of wild oat control as when we went three years of alfalfa or canola-wheat-canola-wheat with […] Read more
