Kochia: ‘the cockroach of the plant world’

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

By Manitoba Co-operator Staff February 26, 2015

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 Manitoba Co-operator Staff February 3, 2015

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

Manitoba Ag Days Inventor's Showcase: Invention from the Netherlands could make big impact on the Prairies

By Greg Berg January 30, 2015

Invented by Harrie Hoeben of the Netherlands, Wingssprayer is designed to allow producers to use fine droplets while crop spraying without worrying about spray drift. The system virtually eliminates wind interference at the spray heads while also opening the canopy so herbicides or pesticides properly cover the plant and treat it further down. Wingssprayer’s Manitoba office is located in Rivers,

Will it or won’t it? Producers discuss Roundup Ready alfalfa

Customer preferences should count when assessing new technology

By Shannon VanRaes January 28, 2015

It’s become a perennial issue for forage seed growers. Will or won’t Roundup Ready alfalfa be released in Canada? The question loomed large at the Manitoba Forage Seed Association’s annual conference in Winnipeg last week, where the issue was raised no less than four times. “We basically feel that there isn’t a need for it,

Concerns about Roundup Ready alfalfa raised at national forage meeting

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

By Allan Dawson December 15, 2014

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

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

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

By Allan Dawson October 6, 2014

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

Editorial: the ‘wicked problem’ of herbicide-resistant weeds

It's not only a problem of chemistry, but human behaviour itself

By Laura Rance-Unger October 6, 2014

When I first tuned into a recent summit on herbicide resistance being broadcast live by webinar from Washington, D.C., my first thought was that I had virtually stumbled into the wrong conference. The keynote speaker wasn’t a weed scientist. He is a sociologist. But as I listened, it became clear this speaker, and the ones

VIDEO: Glyphosate resistance on Manitoba fields

At least one local farmer has resorted to removing kochia by hand

By Allan Dawson August 19, 2014

Glyphosate is arguably the world’s most important herbicide, but glyphosate resistant weeds are on the rise. Two Manitoba fields have glyphosate and group 2 resistant kochia. To delay glyphosate resistance farmers should reduce glyphosate use when possible. That’s the message Manitoba Agriculture, Food and Rural Development weed specialist Nasir Shaikh gave farmers Aug. 7 during the Manitoba

At a time when soil erosion is recognized as one of the biggest threats to the world’s ability to continue feeding itself, it’s disturbing to see weed scientists advising tillage to address invading “superweeds.” There is no question that addressing the lengthening list of weeds that have developed resistance to glyphosate must be a top
