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

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

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

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

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



U.S. EPA to require weed-resistance restrictions on glyphosate

Reuters — U.S. regulators will put new restrictions on the world’s most widely used herbicide to help address the rapid expansion of weeds resistant to the chemical, Reuters has learned. The U.S. Environmental Protection Agency (EPA) confirmed it will require a weed resistance management plan for glyphosate, the key ingredient in Monsanto’s immensely popular Roundup

At least one local farmer has resorted to removing kochia by hand

Glyphosate is arguably the world’s most important herbicide, but glyphosate resistant weeds are on the rise. Two Manitoba fields have glyphosate and group 2 resistant kochia. To delay glyphosate resistance farmers should reduce glyphosate use when possible. That’s the message Manitoba Agriculture, Food and Rural Development weed specialist Nasir Shaikh gave farmers Aug. 7 during the Manitoba
