VIDEO: Herbicide resistance and “old soil-applied” solutions for weeds

Crop Diagnostic School: Know your target weed issues... and weeds that have caused you trouble in the past

By Greg Berg July 15, 2015

To help keep herbicide-resistant weeds at bay, some older soil-applied products are rejoining the fight. At the 2015 Crop Diagnostic School, Jeanette Gaultier, pesticide use specialist with Manitoba Agriculture, Food and Rural Development, talks about which herbicide-resistant weeds producers should watch for and what they need to consider before choosing a herbicide for their situation.

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

By Allan Dawson June 8, 2015

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

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

CropChatter: When do I worry about herbicide injury?

June 10, 2013

The 2013 growing season hasn’t exactly been setting records for heat so far, so some growers may be stuck trying to balance optimal temperatures with their chosen herbicide’s recommended application timings. Crop injury in some situations may be unavoidable, since both temperature and incorrect crop staging affect crop tolerance to herbicides. But not all injury

MANA Canada has introduced two new off-patent co-pack products that are analogues of popular products already available in Western Canada. The new Topline herbicide is a cereal product that includes the active ingredients florasulam and MCPA ester, the same active ingredients as Frontline. It’s registered for use on wheat, oat and barley. In a conference

A penny a plant?

By Laura Rance-Unger January 30, 2013

Back in the days when being a farm kid spelled work and a penny was still worth five Mojos at the local store, Grandpa had us all out there one hot, July afternoon hand roguing his seed oats for a penny a plant. If some agronomists are correct, it’s looking like farm kids of the

Practise zero tolerance to avoid resistant weeds

By Angela Lovell January 17, 2013

If Canadian farmers want to avoid the fate of their U.S. counterparts struggling with glyphosate-resistant weeds such as kochia, waterhemp, and common and giant ragweed, then they’d better practise zero tolerance, says an American weed scientist. “That means no survival rate and no weed seed production,” researcher Jeff Stachler told attendees at the Manitoba Agronomists

Are you ready to give up your WeedEx?

By Shannon VanRaes June 30, 2012

The provincial government wants public input before deciding whether to ban cosmetic pesticide use in Manitoba. Although pesticides used in agriculture — including insecticides, herbicides and fungicides — aren’t included in consultations, a possible ban on cosmetic pesticides would still have repercussions for farmers, said Doug Chorney, president of Keystone Agricultural Producers. “We need to

Search For New Herbicides Continues

By Allan Dawson August 4, 2011

For Len Juras, hunting for new herbicides is a bit like living in one of those country-western “hurtin” songs – minus the twang of course. “The biggest lesson I’ve had to learn is letting go,” the senior research scientist for Dow AgroSciences said here last week. “Over the years I’ve had my heart broken many
