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 USDA Economic Research Service May 12, 2015

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

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 Julienne Isaacs April 21, 2015

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 Shannon VanRaes April 14, 2015

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: Black swan?

By John Morriss April 13, 2015

Among the many topics in the science news releases last week was one from the University of East Anglia in the U.K. “A new study pinpoints five strains of yeast capable of turning agricultural byproducts, such as straw, sawdust and corncobs, into bioethanol — a well-known alcohol-based biofuel,” the release said. We’ve seen similar news

It’s easier than ever to sell snake oil as a fertilizer, supplement or replacement, so for farmers it’s “buyer beware,” warns Don Flaten, a professor of soil science at the University of Manitoba. “It’s what I’d call the Wild West,” Flaten told agronomists attending an Agvise Laboratories meeting here March 18. “With the Wild West

Fun for farmers — watching weeds die

Time-lapse videos help farmers identify signs of herbicide resistance

By Manitoba Co-operator Staff March 18, 2015

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

If you Google “SMAP” two things will come up — a Japanese boy band from the ’90s and a NASA satellite project that will attempt to measure soil moisture on a global scale. The latter is the subject of new soil research from the University of Manitoba. The satellite, set to launch on January 29,

Dispelling common misconceptions about herbicide-resistant superweeds

Herbicide resistance is a major problem, but it is not necessarily a result of gene transfer from genetically modified crops

By Weed Science Society Of America October 28, 2014

Use of the term “superweed” has exploded in recent years and is frequently featured in news reports about herbicide-resistant weeds choking out crops. While there is no science-based definition for superweed, the term is often used to describe weeds believed to have special capabilities that are helping them outcompete other plants in ways never experienced

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

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

Dutch biologist Ingrid van der Meer often meets with disbelief when she talks about her work on dandelions and how it could secure the future of road transport. The reaction is understandable, given most people regard the yellow flowers as pesky intruders in their gardens rather than a promising source of rubber for tires. “People
