Spring weeds rise up well ahead of seeding efforts

Weed forecasts have farmers expecting to reap the consequences of last year’s lack of field work

By
Farmers are gearing up for spring seeding, but the weeds have already made it to the field. Manitoba’s provincial weed specialist, Tammy Jones, says producers are already starting from behind on weed control this year, thanks in large part to harvest conditions last fall. Why it matters: Seeding is stressful enough as is, but farmers
“We’ve actually sent people out into fields with cameras in Saskatchewan and Alberta and Manitoba to actually capture the weeds and crops that are growing right here.” – Daniel McCann, Precision.ai.

Smart spot spraying still has a way to go

Farmers need to be 100 per cent confident these new technologies will work when they hit the field

By
Like any developing technology, spot-spraying systems are far from perfect. In a Manitoba demonstration this July, attendees noted that the WEEDit system missed some smaller weeds during a single pass. That could be addresses by adjusting sensor sensitivity or by turning on “dual mode,” which sprays a constant quarter-rate to take care of less hardy
Manitoba Agriculture has recently confirmed more cases of Tall waterhemp in the province. It’s a tier-one noxious weed that must be destroyed no matter where it’s found.

New cases of Tall waterhemp found in Manitoba

This is a Tier 1 noxious weed that Manitoba Agriculture wants to prevent from spreading

By
Tall Waterhemp has been confirmed in four new Manitoba fields and there are rumours of more, Manitoba Agriculture weed specialist Tammy Jones said in an interview Aug. 2. Tall Waterhemp is a Tier one noxious weed that must be destroyed no matter where it’s found, but that can include hand weeding within crops where practical,

Weeds develop defences

Kochia gets hairy and lamb’s quarters get waxy under harsh conditions

By
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
Kochia or tumbleweeds can spread across fields by the tumbling action and get caught in fencelines. This is an example of landscape-scale weed spread issues.

It takes a village to stop weeds

Researchers say the community nature of the problem of invasive weeds hasn’t been adequately incorporated into control efforts

By
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

Manage herbicide resistance in the tank and out

Industry is pushing both chemical and non-chemical solutions to growing herbicide-resistance problems in Manitoba

It’s time to expand the tool box when it comes to managing weeds. That was the message to attendees at this year’s BASF Knowledge Harvest in Brandon Feb. 13. As of 2015, there were 65 unique weed-resistance cases in Canada, AAFC’s Bob Blackshaw said, a number that rose from near negligible in 1975 and sat

Fall is the best time for controlling foxtail barley

It might be too late in the season now, but there are ways to tackle this weed in the spring too

By
Fall is the best time to control many perennial weeds with glyphosate, including foxtail barley, but it might already be too late. Weed surveys show foxtail barley is on the increase, Manitoba Agriculture weed specialist Jeanette Gaultier said Sept. 20 on her last day in the position, during the Westman Crop Talk webinar. “In the

Keeping kochia in check

New research indicates the importance of early-season control of herbicide-resistant kochia

By
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.
The introduced invasive species spotted knapweed is easily identified once the plant produces its distinctive bright-pink flowers. But at this stage it is already well past the stage where controlling its spread is easy or feasible, warns the Invasive Species Council of Manitoba.

Spotted knapweed could do more harm than leafy spurge

The ISCM declared August Invasive Species Month and is highlighting the risks associated with the potential spread of spotted knapweed

By
The Invasive Species Council of Manitoba wants all Manitobans to be on the lookout for an invasive plant species now spreading across Manitoba that has the potential to do as much or more damage as leafy spurge. Spotted knapweed was first detected in southeastern Manitoba in 2009 but has more recently been found at sites
