Neutralizing weeds’ defence system

Researchers identify a new mechanism to battle herbicide resistance

Plants and unseen soil micro-organisms all need precious space to grow. And to gain that space, a microbe might produce and use chemicals that kill its plant competitors. But the microbe also needs immunity from its own poisons. By looking for that protective shield in micro-organisms, specifically the genes that can make it, a team

U.S. judge allows Roundup-related suits to go to trial

Reuters — Hundreds of lawsuits against Monsanto Co. by cancer survivors or families of those who died can proceed to trial, a federal judge ruled on Tuesday, finding there was sufficient evidence for a jury to hear the cases that blame the company’s glyphosate herbicide for the disease.

Wheat shipment halt seen as temporary

Wheat sales are expected to soon resume to Japan and South Korea. Both nations suspended Canadian wheat imports following the June 15 announcement that Canada had discovered several genetically modified (GM) wheat plants in southern Alberta. But both are expected to come back to the market shortly, while exports to others won’t be affected, according

Webinar Australia: Chemical company BASF has launched a free resource for farmers on herbicide resistance, including lessons from Australia.

Transplanting herbicide-resistance advice from Down Under

Australia has something to teach Canadian farmers about herbicide resistance, at least, according to BASF’s latest online resource

On the other side of the world, farmers have learned some valuable insights about herbicide resistance that you can share. In Australia they’ve long been fighting this battle and the land Down Under has learned some tough lessons. The International Survey of Herbicide Resistant Weeds found Canada is third in the world in terms of


A new problem weed arrives in Manitoba fields

A new problem weed arrives in Manitoba fields

Our History: June 2001

One of our front-page stories on June 28, 2001 was on a new problem weed — glyphosate-resistant canola. Several farmers, including some who had never grown Roundup Ready canola, were reporting the plants in their fields. A Monsanto representative acknowledged the problem but said it was not widespread and it was sending workers to hand-pick

Extended-tolerance canola now on deck for 2019

Giving growers a wider window to spray in-crop weeds with glyphosate, the new platform for Monsanto’s future canola trait stacks is now booked to make its way into the Canadian market next year. The U.S. seed and chemical company’s Canadian arm announced last week it plans to commercialize TruFlex canola in 2019, following plot trials


Editorial: In the weeds

Canada has a brewing weed problem, and we’re not talking about the looming legalization of cannabis. This is an older problem, but with a modern twist, in the form of constant selection pressure from chemical control products and the resulting herbicide-resistant weeds. Manitoba farmers have the dubious distinction of being among the first in the

Glyphosate-resistant kochia is still rare in Manitoba, but the time to prevent it from spreading is now.

ON THE GROW: Herbicide resistance is spreading quickly

Manitoba Agriculture is warning about new and looming threats when it comes to resistant weeds

Manitoba’s provincial weed specialist is urging a harder line on herbicide resistance. “Zero tolerance is really where you need to be,” Tammy Jones of Manitoba Agriculture said. “Controlling your escapes. Control them with mowing; control them with tillage. If you really want to, control them with hand weeding, but if you have resistant wild oats

Germany moving ahead with plans to restrict glyphosate

Berlin | Reuters — German Agriculture Minister Julia Kloeckner on Tuesday said she was finalizing a draft regulation to end use of glyphosate herbicide in household gardens, parks and sports facilities, and to set “massive” limits for its use in agriculture. The chemical, made by Monsanto, is at the centre of a heated debate in

AAFC’s Bob Blackshaw talks herbicide-resistance problems and solutions at Brandon’s BASF Knowledge Harvest Feb. 13.

Manage herbicide resistance in the tank and out

Industry is pushing both chemical and non-chemical solutions to growing herbicide-resistance problems in Manitoba

It’s time to expand the tool box when it comes to managing weeds. That was the message to attendees at this year’s BASF Knowledge Harvest in Brandon Feb. 13. As of 2015, there were 65 unique weed-resistance cases in Canada, AAFC’s Bob Blackshaw said, a number that rose from near negligible in 1975 and sat
