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

By
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

By
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

By
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

By
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

Editorial: Just follow the label

By
How should farmers and the agricultural community react to news that a French agency has labelled glyphosate as “possibly carcinogenic”? We’ve already seen the battle of the competing press releases questioning the science. The usual anti-GMO suspects are no doubt having a heyday. Farmers, as usual, will be stuck in the middle. Rather than picking

Glyphosate classified as ‘probably carcinogenic’

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

By
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

Forage Seed Canada seeks allies to keep Roundup Ready alfalfa out

Forage seed growers fear they and hay exporters will lose valuable markets because of GM contamination


By
Heather Kerschbaumer just lost another forage seed sale because of GM contamination, reinforcing her opposition to allowing Roundup Ready alfalfa production in Canada. The Fairview, Alta., seed grower and president of Forage Seed Canada says the association is seeking allies to help block Roundup Ready alfalfa from commercial Canadian production until certain conditions are met.

Fun for farmers — watching weeds die

Time-lapse videos help farmers identify signs of herbicide resistance

By
The weed science team at Ohio State University has come up with a set of videos that farmers might enjoy even more than binge watching “House of Cards” — weeds slowly dying after being sprayed with herbicides. For every second of movie time shown, one hour of real time passes in the time-lapse videos. The

Kochia: ‘the cockroach of the plant world’

Weed can duplicate extra copies of a gene 
which is resistant to glyphosate

By
A Kansas State University weed scientist says he’s figured out why glyphosate-resistant kochia is like a “cockroach of the plant world.” Mithila Jugulam, assistant professor of agronomy, led a study that looked at how kochia evolved resistance to the herbicide. The researchers found that kochia has evolved to have multiple copies of a gene code

An ag-minister’s advice goes wrong

Our History: January 2001

By
The advice may have been good, but the timing was wrong. As reported in our Jan. 25, 2001 issue, Agriculture Minister Rosann Wowchuk speaking at Ag Days unveiled a 70-page report touting Manitoba’s advantages in beef production, saying the province had all the resources to double its cow herd. On the other hand, a report
