Building a culture of weed control

Experts highlight importance of collaboration to contain problem weeds

Glacier FarmMedia – Distributing the message about problem weeds tends to fall on the shoulders of private and retail agronomists, says Manitoba Agriculture weed specialist Kim Brown. “I reach a fair number of farmers in this province, but we probably have 8,500 registered farmers, and we can’t reach them all. So, we rely heavily on […] Read more

Glacier FarmMedia – Attention to fall weed control is needed as harvest nears its end. Speaking during a Manitoba Agriculture webinar Sept. 25, provincial weed specialist Kim Brown singled out weeds that thrive in salinity, which concerned many producers this spring.

Weeds have adapted but so have Canadian farmers: Bayer

The company says it is sharing information with producers on the value of using strategies to manage weed resistance

WINNIPEG — Bayer began its acquisition of Monsanto in 2016, and the takeover was finalized in 2018. With the transaction, Bayer became the rights holder of Roundup, which Monsanto commercialized in 1974. The patent on Roundup expired in 2000, allowing other companies to produce generic versions of glyphosate, the ingredient in Roundup that kills weeds. […] Read more

Early weed identification means easier control

Misidentifying a young weed can make managing it much harder and more expensive later in the growing season

Glacier FarmMedia – Different weeds might warrant different responses if they’re found in a field. The problem is, they might look frustratingly similar in their early stages. “You need to be going out for waterhemp or Palmer amaranth before they’re four inches tall,” said Manitoba Agriculture weed specialist Kim Brown. Those species have provoked a […] Read more

Outlook focuses on problem Prairie weeds

Glacier FarmMedia – The past few seasons have been a challenging time for farmers on the Canadian Prairies. Extreme heat, lack of precipitation and steep increases in production costs have caused some sleepless nights for many producers. As if those weren’t enough to contend with, another potential threat to crops will soon rear its ugly […] Read more

The gaps in Palmer amaranth, waterhemp prevention

No one wants Palmer amaranth or waterhemp to become bigger weed worries than they already are in Manitoba, and there’s work currently focused on making sure that doesn’t happen, but locally based knowlege is still thin on the ground. The two boogeymen of the weed realm were recently the subject of a successful resolution brought […] Read more

Waterhemp was first confirmed in Manitoba in 2016 and has since spread through eastern and into central Manitoba and has popped up as far west and north as the Rural Municipality of Dauphin near Riding Mountain National Park and the RM of Ellice-Archie along the Saskatchewan border.   |  File photo

Manitoba farm group takes aim at two noxious weeds

Keystone Agricultural Producers will set its sights on two emerging noxious weeds: waterhemp and Palmer amaranth. A resolution brought forward by University of Manitoba agriculture diploma students during KAP’s March advisory council meeting March 27 aims to give more support to farmers to beat back Manitoba’s growing problem. The resolution would see KAP fund testing […] Read more
