More than one million acres of Canadian farmland have glyphosate-resistant weeds growing on them, including 43,000 in Manitoba, according to an online survey of 2,028 farmers conducted by Stratus Agri-Marketing Inc. based in Guelph, Ont. The shockingly high Canadian numbers met with skepticism from some experts who suggest farmers might be mistaking hard-to-kill weeds with glyphosate resistance. But others say the farmers are probably right. Even though there hasn’t been a single documented case of a glyphosate-resistant weed in Manitoba, the 281 Manitoba farmers surveyed said they believe there’s glyphosate-resistant kochia on 23,000 acres in this province.
