Invasive weeds have genetic advantage

A single trait, which developed independently in multiple situations, drives invasive success

By
They say a weed can grow almost anywhere, and researchers at the University of British Columbia have found the reason is genetic. They looked at one successful weedy plant, the Jerusalem artichoke, to see why it survives, thrives and spreads. Understanding how invasive plants evolve and the genetic underpinnings that enable them to thrive in

Hardy Joe Pye Weed

Because it is native to the area it’s tough and responds well to our harsh climate

By
If you like native plants, then you probably already have a Joe Pye Weed (Eupatorium maculatum) in your garden. Native plants are reliably hardy, they respond well to local conditions and are not “finicky” to grow — a good thing — because in our harsh climate conditions plants need to be tough to survive and

Six factors to consider if your soil moisture level is low

By
To date, all indications are pointing to a dry spring, given the below-average precipitation received in many areas of the Prairies this winter. There are exceptions to every rule of course, but a lot of farmers had relatively dry soils going into winter, so we asked some agronomists and provincial crop experts what factors could
Kudzu, or Japanese arrowroot, is an invasive vine that climbs and encases anything it encounters, including native vegetation like these trees in Mississippi. It’s sometimes called ‘the vine that ate the South.’

Scientists want to understand behaviour of invasive weeds

Why are certain plants able to enter a new ecosystem and run riot?

By
Is it possible to predict which non-native plant species will become invasive weeds and when? According to research featured in the journal Invasive Plant Science and Management, the answer is “hopefully yes.” Researchers say invasive species generally follow a three-phase development curve — from lag to expansion to plateau. The length and rapidity of the

Robots are the future of weed control, one researcher says

By
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.

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
