Weeds like kochia, pictured here in lentils, got a competitive advantage from the hot, dry conditions this summer. And more seeds returning to the soil seed bank could boost weed pressure in the coming year.

Drought may have set up weeds nicely for 2022

And while disease levels dropped last year, they could easily come roaring back in 2022

Reading Time: 4 minutes This summer’s hot, dry conditions made weeds harder to manage this year — and that’s not good news for next year. “This year, precipitation was one of the biggest driving factors for what we saw showing up in fields,” said federal research scientist Charles Geddes. “We ended up seeing a lot more flushes of weeds […] Read more

Spot spraying can reduce herbicide application by up to 90 per cent, says distributor Croplands Equipment. And ensuring weeds get a full dose of a herbicide can combat resistance.

Spot spraying gets lots of looks but many farmers seem hesitant

Some are holding off on ‘green-on-brown’ weed tech until it costs less and does more

Reading Time: 3 minutes When it comes to precision-farming technology, automated spot spraying of weeds would be a science fiction dream come true. If it lives up to its promise, farmers would save countless dollars in reduced herbicide use, benefit the environment, and maybe even gain the upper hand in battling herbicide resistance. In Canada, the face of spot […] Read more


There are 75 regulated and prohibited noxious weeds in Alberta.

Weed-free forage program relaunched

Some counties are now offering inspections to ensure invasive weeds are not present in hay

Reading Time: 2 minutes A program aimed at preventing the spread of invasive and noxious weeds via hay is getting a second shot. Alberta’s first go-round with a Certified Weed Free Forage program a decade ago never fully took off but the Alberta Invasive Species Council has revived the initiative. “Use of certified weed-free forage is a best management […] Read more

This is not a pretty picture but it’s one that’s increasingly common as herbicide-resistant weeds, such as kochia, become the rule rather than the exception.

The clock is ticking on old-school ways of weed control

Resistance is rampant and producers need a more strategic approach, including herbicide layering

Reading Time: 3 minutes Time’s just about up. Crop growers won’t be able to spray their way out of problem weeds for much longer if herbicide resistance continues to spread, says one of the country’s top weed scientists. “We’re seeing multiple-herbicide resistance show up in a few different weed species on the Prairies,” said federal research scientist Charles Geddes.

This fellow’s ancestors hailed from Serbia, but the Rhinusa pilosa — a.k.a. stem-galling weevil — now makes its home in Alberta and B.C., where it feeds on yellow toadflax, a weed that infests pastures.

There’s foreign workers in the bug world, too — and they attack weeds

Bringing in weed-attacking pests is a laborious process but it’s often the only option for pastures

Reading Time: 3 minutes There are many ways to control weeds. Rose De Clerck-Floate’s favourite is to reunite them with their longtime enemies from the old country. “All of the weeds here can come from other parts of the world, mostly Europe and some from Asia, and establish here without the organisms that keep them in check in their […] Read more

Canopy Growth to buy rival Supreme Cannabis

Deal comes as pot demand lights up

Reuters — Canopy Growth Corp. said Thursday it will buy rival Supreme Cannabis for $323.3 million, as the world’s biggest cannabis producer bolsters its portfolio to tap surging demand. Shares of Canopy, up 15 per cent this year, fell around 4.6 per cent to $36 after it announced the cash-and-stock deal for Supreme, which owns […] Read more


Weed seed bank is higher this year and late spring favours weeds, too, says federal research scientist Breanne Tidemann.

Wet fall and late spring a recipe for increased weed risk

Pre-seed burn-off will depend on what’s popping up in your fields, so scout early, says weed scientist

Reading Time: 2 minutes You won’t hear weeds complaining about the weather — which adds up to another headache for producers. “Because we were so dry last spring, there were quite a few fields that didn’t get a pre-seed burn-off because there was nothing growing yet. I don’t think that’s going to be the same circumstance this year,” federal […] Read more
