How to fall apply Avadex and Fortress

Getting the application technique right will make these products more effective

By
Apply Avadex and Fortress in the fall after the surface soil temperature is below 4 C and within three weeks of soil freeze-up. This situation generally occurs by October 1 across Western Canada. A single heavy harrow pass is sufficient for incorporation in minimum- and zero-till fields. Good soil contact is necessary for these herbicides
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

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

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
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

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

Manitoba’s first glyphosate-resistant weed confirmed

The good news is, the weed was found at only two sites out of 283 surveyed last fall

By
Manitoba has its first official glyphosate-resistant weed, and as expected, it is kochia. But out of 283 fields surveyed last fall, only two were found with glyphosate-resistant kochia. Both are in the Red River Valley. “I was surprised about where it was found,” Bruce Brolley, Manitoba Agriculture, Food and Rural Development’s (MAFRD) crops knowledge centre
