Kim Brown-Livingston says she’s optimistic as she takes the role of provincial weed specialist. “We have a great future,” she said. “We’re going to continue on, and our farmers are doing a really good job of it now.” Brown-Livingston previously held the role of weed specialist from 1998 to 2013 before moving on to work
This year has brought its own quirks to weed control. Kochia is out in force again this year, provincial weed specialist Tammy Jones said. The plants’ fuzzy leaves create their own challenges for herbicide contact, even if the kochia is not showing glyphosate resistance. Glyphosate-resistant kochia has become a significant headache and cause for worry
Kochia was emerging in Manitoba fields last week and most of it is presumed resistant to Group 2 herbicides, says Manitoba Agriculture weed specialist Tammy Jones. Many could also be glyphosate tolerant, but it’s hard to know to what extent, she said in an interview April 24. “I know that it is distributed fairly thoroughly
Invasive weeds are a problem that defies solution, and only seems to get worse. That’s because they’re a community problem that cross property boundaries, according to weed scientist Muthu Bagavathiannan, of Texas A&M. Finding a real solution will involve recognizing the nature of weeds as a community problem, and managing them accordingly, he and other
When Tammy Jones’ phone rang last year as often as not it was farmers fed up with kochia spreading in their fields. The Manitoba Agriculture weeds specialist dubbed the tumbleweed ‘weed of 2018,’ in a talk at St. Jean Farm Days last week. “We saw a lot of it,” she said. “It felt like anyone
Producers may be looking for a way to beat back kochia, but what does that mean for the salinity problems lurking in the soil? Saline patches were common this year after a second season of below-average moisture. Read more: The year of the tumbleweed “The fluctuations in soil moisture are very linked to the soil
It’s a good year to be a kochia plant. That should come as no surprise to growers. The tumbleweed-like plant has become a common sight this year, popping up over crop in what seems like larger and more frequent patches, some of which now show less response to glyphosate. Weather conditions were a large part
Herbicide-resistant kochia is a big problem in the U.S. Great Plains states, and has appeared in limited numbers in Manitoba over the past few years. Now researchers, writing in the latest edition of the journal Weed Science, are beginning to reveal more about how the weed works. Kochia typically begins to emerge in the U.S.
Farmers may lose the war against herbicide-resistant weeds if they don’t start using other forms of control besides chemicals, a University of Manitoba weed scientist says. Herbicide resistance, common in other countries, is starting to appear in Western Canada and it’s just a matter of time before it becomes prevalent here too, Rob Gulden warns.
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
