A gritty new tool in the war against weeds

Weed and feed your crop with blasted soybean meal

By
Researchers with the University of Illinois have come up with a new tactic in the war against weeds: blasting. “Abrasive weeding,” a strategy that may prove most useful for small-scale organic growers, is proving to be “surprisingly effective,” university researchers say in a release. In conjunction with plastic mulch, abrasive weeding reduced final weed biomass
There are signs indicating glyphosate-resistant kochia is still rare in Manitoba, but farmers need to be vigilant to keep it that way.

Signs indicate glyphosate-resistant kochia still relatively rare in Manitoba

Farmers are being asked to submit suspected cases for testing and encouraged to remain vigilant

By
Glyphosate-resistant kochia still appears to be relatively rare in Manitoba, but that’s no reason for farmers to become complacent, the provincial government’s weed specialist says. In fact, the situation calls for more vigilance, rather than less, Jeanette Gaultier, weed specialist with Manitoba Agriculture, Food and Rural Development (MAFRD) said. Glyphosate-resistant kochia was confirmed in just

Less nitrogen equals less volunteer canola

Tighter row spacing may put the squeeze on late-emerging or slow-growing weeds, but not so for volunteer canola

By
Looking to reduce volunteer canola in your soybeans? Hold off on that extra nitrogen, or better yet, find a field that’s been depleted. Standing amid research plots at the Ian N. Morrison Research Farm near Carman, University of Manitoba PhD student Charles Geddes explained some of the work being done to combat volunteer canola during

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

By
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.

Manitoba overhauling Noxious Weeds Act

Noxious weeds will be listed in three tiers with control action 
based on the threat to agriculture and natural areas

By
The Manitoba government is overhauling one of the oldest laws on its books — the Noxious Weeds Act — to bring it into line with current weed threats in the province. If passed, Bill 32, the Noxious Weeds Amendment Act, will put into statute much of what is already common practice — controlling weeds commiserate

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
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

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

Southwestern Manitoba — semi-arid to semi-fluid

Dedicated minimum- and zero-till farmers are now dragging out tillage 
equipment that’s been in store for years

By
When Ryan and Wade Flannery began working on the drilling rigs to supplement grain farming, they did not imagine that several years later they would be working for oil companies year round. “We (initially) went to the drilling rigs for something to do for the winter and now it’s turned into a full-time deal,” said

Tips for herbicide weed control when it’s cool and wet

When weeds are growing slowly they absorb less herbicide, while stressed crops are more susceptible to injury

By
Cool, wet weather, especially in southwestern Manitoba, has delayed seeding and now it’s complicating weed control. Muddy soils have delayed, or prevented farmers from doing a pre-plant weed burn-off allowing weeds to get bigger than the optimum stage for herbicide control.

Get on controlling foxtail barley early

The weed is becoming more prevalent in the southwest

By
Foxtail barley is getting worse in southwest Manitoba and it’s best controlled before seeding, says Lionel Kaskiw, Manitoba Agriculture, Food and Rural Development’s farm production specialist in Souris. “It seems to be a weed that has taken over since 2011 in some fields and producers are having some issues on how to control it,” Kaskiw
