Even less competitive crops can benefit from an integrated weed management strategy.

Crop establishment important for weed management

Combining many tools into an overall integrated weed management strategy is a winner

By Angela Lovell October 30, 2018

There are many components to integrated weed management (IWM) including crop rotation, seeding rates, chemical, cultural and mechanical controls, but one of the most vital aspects of any successful IWM is crop establishment, says Dr. Rob Gulden of the University of Manitoba. At this year’s Crops-A-Palooza event in Portage la Prairie, researchers including Gulden manned

Editorial: In the weeds

By Gord Gilmour May 17, 2018

Canada has a brewing weed problem, and we’re not talking about the looming legalization of cannabis. This is an older problem, but with a modern twist, in the form of constant selection pressure from chemical control products and the resulting herbicide-resistant weeds. Manitoba farmers have the dubious distinction of being among the first in the

Glyphosate-resistant kochia is still rare in Manitoba, but the time to prevent it from spreading is now.

ON THE GROW: Herbicide resistance is spreading quickly

Manitoba Agriculture is warning about new and looming threats when it comes to resistant weeds

By Alexis Stockford May 17, 2018

Manitoba’s provincial weed specialist is urging a harder line on herbicide resistance. “Zero tolerance is really where you need to be,” Tammy Jones of Manitoba Agriculture said. “Controlling your escapes. Control them with mowing; control them with tillage. If you really want to, control them with hand weeding, but if you have resistant wild oats

Robots are the future of weed control, one researcher says

By Manitoba Co-operator Staff January 22, 2018

Forget about that old hoe — it’s time to go high tech with weed control. Researchers at the University of California-Davis say robotic weeders are already making headway in high-value vegetable crops, fuelled by a lack of chemical controls and lack of affordable labour. Steven Fennimore, an extension specialist at the university, pegs the cost

How dense is the perfect canola stand?

Economic-focused studies say lower stand density might mean bigger profit, while other experts warn that it might be short-term financial gain for long-term agronomic pain

By Alexis Stockford July 25, 2017

Have canola growers been targeting too-dense stands? According to one oilseed specialist that might be the case, but not everyone agrees. Murray Hartman, oilseeds specialist with Alberta Agriculture and Forestry put forward the controversial suggestion during a presentation at Canolapalooza June 22 in Portage la Prairie.
