Herbicide resistance is a global problem that requires a local solution, says
Kate Sanford Mitchell. Farmers, researchers and industry from North America 
to Australia are trying to find effective ways to control resistant weeds.

Farmers don’t create herbicide resistance, but management practices can encourage it

By
While many farmers think about herbicide resistance in Australia, the U.K. and the U.S., the reality is that it’s a Canadian problem, too, says Kate Sanford Mitchell. We need to listen to extension specialists who are sounding the alarm about herbicide resistance, she adds. “Weed resistance is a global problem that requires a local solution,” […] Read more

Top 10 weed management practices

Herbicide resistant weeds are no longer a novelty, they’re the norm

By
Hugh Beckie, a research scientist with Agriculture and Agri-Food Canada, said it’s a challenge to get farmers to implement herbicide-resistance best management practices (BMP) because growers are diverse, and one size doesn’t fit all. But Beckie has found that growers who use BMPs tend to have less herbicide resistance. So, in the spirit of David […] Read more

Fighting herbicide-resistance

Herbicide resistant weeds aren’t a novelty anymore — now they’re just the norm

By
While herbicide resistance isn’t a new problem, it is a growing one. Today 80 countries report herbicide-resistant weeds, says a researcher. And Canada is near the top of that list. Dr. Ian Heap heads the international survey on herbicide-resistant weeds, and reported those findings at the Herbicide Resistance Summit in Saskatoon this March. “North America […] Read more

VIDEO: The potential for post-harvest weed control in Western Canada

From the International Weed Resistance Summit

By
With machines like the Harrington Seed Destructor grabbing international headlines, many in Canada wonder whether post-harvest weed control could be the answer to herbicide resistance. Breanne Tidemann, a Ph.D. student at the University of Alberta, decided to find out. Lisa Guenther caught up with Tidemann at the Herbicide Resistance Summit in Saskatoon this March to […] Read more

From the International Weed Resistance Summit

By
At the Herbicide Resistance Summit this past March, Dr. Hugh Beckie presented the results of the latest weed survey in Saskatchewan. Agriculture and Agri-Food Canada researchers hadn’t finished screening for herbicide resistance. But Beckie expects to see herbicide-resistant weeds on over 50 per cent of cultivated land in Saskatchewan, he told Grainews reporter Lisa Guenther. […] Read more

Saskatoon hosted the International Weed Resistance Summit this March. Speakers at the conference delivered a dose of reality on the growing herbicide resistance program. One of those speakers was Dr. Ian Heap, who leads the International Survey of Herbicide-Resistant Weeds. Grainews reporter Lisa Guenther teamed up with Robin Booker of The Western Producer to cover the […] Read more

Crop Advisor’s Casebook: Cleaver in canola a mystery

A Crop Advisor's Solution from the December 2, 2014 issue of Grainews

By
It was the later part of June when I received a concerned call from Riley, a grower in Marshall, Sask. The grain farmer, who grows primarily canola, wheat and barley on his 5,000-acre spread, was having a problem with cleavers in his canola fields despite his use of an in-crop herbicide. “I don’t’ think it […] Read more

Herbicide tolerant canola, but not GMO

An SU-tolerant canola is just the first of what Cibus hopes will be a long list of trait improvements

By
Jim Radtke may not be a gene whisperer, but his California-based plant genetics company, Cibus, has developed technology that allows it to communicate with and influence plant genes to produce desired traits. Whether it be something like herbicide resistance, or drought tolerance in field crops, or producing a different-colored petal in a flower, as examples, […] Read more

Herbicide resistance rampant in Australia

In Australia, herbicide resistance is an industry-wide problem that needs solutions

By
Western Australia’s farmers are fighting herbicide resistant weeds by doing everything from burning windrows to using chaff carts. But what works in one state doesn’t necessarily translate to another. In the state of Victoria, the longer growing season means much of the annual ryegrass has fallen into the base of the crop by harvest, says […] Read more
