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

Glyphosate resistance: Change now or pay later

A USDA-ERS report shows managing glyphosate resistance is more cost effective than ignoring resistance and farmers need to work together

The United States Department of Agriculture Economic Research Service recently published the results of a study into the economics of glyphosate-resistance management on U.S. corn and soybean farms. Through surveys and computer models it determined the relative costs of ignoring the problem versus taking action to address it. The following is an excerpt from that

Health Canada completes review of glyphosate

Minor labelling changes are proposed

Health Canada is seeking public comments on its proposal to approve the ongoing registration of glyphosate, the widely used weed killer better known as Roundup. The department says its evaluation of scientific information “found that products containing glyphosate do not present unacceptable risks to health or the environment when used according to the proposal label

New herbicides help producers mix up modes of action to fight resistance

Farmers can fend off herbicide-resistant weeds and make money by changing up their weed control program

How can thinking about resistance help us economically in the short and long term?” This was a question posed by Brad Ewankiw, a project manager for FMC Canada, during a presentation on FMC’s new herbicides at North Star Genetics’ annual soybean grower information day in Morris March 27. Ewankiw pointed to pre-emergent residual herbicides as

Glyphosate: Advice to producers remains the same

Without the introduction of herbicide-resistant canola, yields would likely be much lower than they are today

The Canola Council of Canada isn’t suggesting producers make any changes following a move by the International Agency for Research on Cancer (IARC) to label glyphosate as “probably carcinogenic.” Glyphosate, the primary active ingredient in Roundup, along with malathion and diazinon received the designation due to “limited evidence of carcinogenicity in humans and sufficient evidence



Scientist defends WHO group report linking glyphosate to cancer

Reuters — A World Health Organization group’s controversial finding that the world’s most popular herbicide is “probably carcinogenic to humans” was based on a thorough scientific review and is a key marker in ongoing evaluations of the product, the scientist who led the study said Thursday. “There were several studies. There was sufficient evidence in

Glyphosate classified as ‘probably carcinogenic’

Monsanto questions results of report, which also includes diazinon, malathion and parathion

The decision by an international group of cancer experts to classify the active ingredient in Roundup herbicide as “probably carcinogenic” has drawn fire from the product’s main maker. The International Agency for Research on Cancer (IARC), a France-based arm of the World Health Organization, last Friday released its working group’s evaluations on the cancer-causing potential
