Producers battling herbicide-resistant weeds will need to add diversity to their rotations, says federal research scientist Breanne Tidemann.

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

Wild oats is currently resistant to the most number of herbicide groups of any weed.

‘Wake-up call’ needed for resistance

Provincial crop expert says it’s time to stop pretending it’s not ‘a huge issue’

Reading Time: 3 minutes Weed resistance has been an issue in crop production for many years, but is coming to the forefront as increasing numbers of weeds are no longer responding to herbicides. “Most producers are aware of the issue, but unless it affects them directly, don’t see it as a huge issue,” said provincial crop specialist Harry Brook.

Assessing the threat from a weed starts with identifying it. For example, whitlow grass (left) isn’t a big threat, but scentless chamomile (right) is, says provincial crop specialist Harry Brook. photos: wiki commons

Know your enemy and its destructive potential, says provincial crop specialist

There’s a critical window for controlling weeds, but it depends on both the crop 
and the threat posed by individual species

Reading Time: 2 minutes All crops have a critical weed control period when they are most susceptible to significant yield loss from weed competition. The critical weed control period for canola is around 17 to 38 days after emergence. Peas can be as early as two weeks after emergence. “Other, more competitive crops, like the cereals, have a less […] Read more



A ‘mystery syndrome’ is stunting canola buds, and Alberta researchers still aren’t sure what’s causing it.

‘Mystery’ canola attacker stumps scientists

Researchers have been trying to solve this ‘whodunit’ for years but so far, no one has been able to crack the case

Reading Time: 2 minutes It’s a classic ‘whodunit’ — the Case of the Confounding Canola Killer. And Alberta researchers are still scratching their heads over it 15 years later. “Since 2002, we’ve been finding this ‘mystery syndrome,’ and I don’t have a cause for it,” said provincial oilseed specialist Murray Hartman. “We get one nice flower that turns into […] Read more
