Scientists are continuing to discover just what a difficult foe the weed Palmer amaranth can be. It can cause yield losses as high as 80 per cent for soybean growers and has already developed resistance to six classes of herbicide since its discovery in North America 100 years ago. It’s recently been found in North

Herbicide resistance quietly growing problem in Manitoba

Multi-pronged weed control strategies that go beyond chemicals are urged by researchers

By
Farmers may lose the war against herbicide-resistant weeds if they don’t start using other forms of control besides chemicals, a University of Manitoba weed scientist says. Herbicide resistance, common in other countries, is starting to appear in Western Canada and it’s just a matter of time before it becomes prevalent here too, Rob Gulden warns.

Editorial: Peace and prosperity

By
Maybe it’s time for agriculture to climb down from its wartime footing. For decades now it’s been a battle as farmers fight nature, red in tooth and claw, to prevent crop damages and loss. It’s hardly surprising when you consider the historical context out of which our modern Green Revolution agriculture sprang. It took off

The farms that are winners tomorrow will be run by farmers who are proactively understanding and defusing production problems today. There are a number of growing issues that could be a disaster tomorrow, but growers can prevent them if they’re committed to doing the right thing now. The best example, and the one that’s a

Monsanto aims to give farmers better information in weed resistance fight

The company is countering its competitors who tout their herbicides 
as tools in the fight to avoid herbicide-tolerant weeds

By
Monsanto Canada is fighting what it says is “fear-based rhetoric floating around about farming practices and (weed) resistance in Canada.” In a recent full-page advertisement in several farm newspapers, including the Manitoba Co-operator, Michiel De Jongh, Monsanto Canada’s president and general manager, said Monsanto should’ve addressed herbicide-resistant weeds sooner. “When you began to battle herbicide

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

Tank mixing weed killers helps delay herbicide-resistant weeds

But don’t forget to rotate crops, including fall seeded and perennials, 
advises AAFC’s Hugh Beckie

By
Tank mixing two herbicides with different modes of action targeting the same weed is a good way to delay the development of herbicide-resistent weeds, a study by weed scientists at the University of Illinois and United States Department of Agriculture concludes. “We don’t say that mixing is the end-all solution,” study co-author Pat Tranel of
