Editorial: Just follow the label

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

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

Monsanto seeks retraction for report linking herbicide to cancer

Reuters — Monsanto, maker of the world’s most widely used herbicide, Roundup, wants an international health organization to retract a report linking the product’s chief ingredient to cancer. The company said Tuesday that the report, issued on Friday by the World Health Organization’s International Agency for Research on Cancer (IARC), was biased and contradicts regulatory

Fun for farmers — watching weeds die

Time-lapse videos help farmers identify signs of herbicide resistance

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

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

Editorial: Changing how we think

Back in the days when Prairie farmers were still in the experimental phase of adopting what is now known as conservation agriculture, I remember interviewing a farmer who had gone all the way and embraced zero tillage. He said it was an exercise in frustration bordering on failure until he realized the transition involved more

Concerns about Roundup Ready alfalfa raised at national forage meeting

Many forage and forage seed importers have zero tolerance for GM crops, including alfalfa

Asingle genetically modified (GM) canola seed cut the value of Heather Kerschbaumer’s timothy seed in half — costing her $20,000. That’s why the seed farmer from Fairview, Alta., fears the introduction of GM Roundup Ready alfalfa. “In my opinion I think it would be a devastating blow to the seed industry, especially for our Peace

Herbicide-resistant black-grass is costing English farmers $55 to $100 an acre in herbicide costs and if Canadian farmers aren’t careful they can expect similar problems with herbicide-resistant grass weeds, Gowan’s John Edmonds warned herbicide sellers last week.  photo: john edmonds, Gowan

Old chemistry conscripted in battle with herbicide-resistant weeds

It’s an expensive fight in Europe that farmers here can expect to have if they don’t adjust first

Avadex and Fortress are old soil-applied, pre-emergence herbicides with a new purpose — helping delay the onset of herbicide-resistant weeds. And fall is the right time to apply both, herbicide retailers were told at a meeting here Sept. 22 held by Gowan Canada. Manitoba already has some herbicide-resistant weeds, including glyphosate- and Group 2-resistant kochia
