Weed scientists say it’s a matter of when, not if, wild oat populations here will develop resistance to glyphosate —  as they’ve now done in Australia.

Glyphosate-resistant wild oats are in Australia, and that’s bad news here

Aussies usually see resistance first, with Canada close behind – and that means a ‘scary’ scenario for Prairie farmers

Glyphosate-resistant wild oats have been found in Australia and that should be a wake-up call to any farmer who thinks it couldn’t happen in Canada. “This is the first confirmed case of glyphosate-resistant wild oats in the world,” said federal research scientist Breanne Tidemann. “It’s something we’ve been concerned about but no one has ever […] Read more

The Harrington Seed Destructor has come a long way since it was first developed in 2012. Originally a tow-behind unit that attached to the back of the combine, the new weed seed management tool is now a mill that can be integrated with the combine — at half the price.

Is the weed seed ‘destructor’ ready for prime time in Alberta?

Invention is now cheaper and easier to use, but it's still ‘a hard sell’ for farmers

In the battle against herbicide-resistant weeds here in Alberta, the Harrington Seed Destructor might just win us the war — if farmers can justify the $100,000 price tag. “If herbicides are still working, it can be hard to convince producers to spend that kind of money to purchase this kind of equipment,” said federal research […] Read more


Kochia has taken over this abandoned well site and stands nearly as tall as Kevin Serfas. The Turin farmer says his calls to the energy companies that own several dozen similar sites on his family’s farming operation go unanswered. And managing the weeds would require “a full-time guy,” he said.

Farmers lose — and weeds win — when energy companies walk away

When well sites are abandoned, the rent cheques 
often stop while the noxious weeds flourish

“Kochia six feet tall and completely covering the whole leases. We have many that look like this. When I phone, no one even answers the phones.” This tweet from Lethbridge-area farmer Kevin Serfas in August likely could have been written by any one of hundreds of Alberta producers with abandoned well sites on their farms.

This Alberta field is being overrun by kochia — likely a type resistant to two or even three modes of action. Canada already ranks third in terms of herbicide-resistant weed and the problem is quickly worsening, says a leading expert.

In the weeds: Canadian farmers can’t stay ahead of herbicide resistance

The problem is huge, rapidly getting worse, and non-chemical weed control is becoming a necessity

Farmers won’t be able to spray their way out of this — Canada is now third in the world when it comes to weeds able to survive pesticides that used to kill them. “We’re quickly being overrun by herbicide-resistant weeds,” said federal research scientist Charles Geddes. “There have been difficult herbicide-resistant weeds in the past, […] Read more


Uneven boom height is one of several issues that can lead to “underdosing” when spraying.

Spray variability may be costing you big bucks

Several factors can cause uneven spraying — and they almost always come down to speed

In some parts of the field, as much as half of the herbicide you spray may not hit the target, says a spraying expert. And while there are a host of factors involved — including turns, boom height variability, and turbulence — more often than not, the culprit is speed, said Tom Wolf. The result […] Read more

These Manitoba Department of Agriculture photos show that weeds are more obvious when looking 
down at a wheat crop (r) than looking at it sideways.

It’s the time of year when crop scouting pays big dividends

Weed escapes, herbicide resistance, disease, and pests can all be assessed after spraying, says expert

Spray, then scout, says provincial crop specialist Mark Cutts. “It is very important to recognize that scouting after a herbicide application is vital to weed control, said Cutts. “In the majority of cases, producers will find that the chemicals have worked. However, in certain situations, field scouting may show the weeds weren’t properly controlled. Producers […] Read more


Ensuring legumes aren't seeded too deep is a critical step in establishing a high-legume pasture.

Going beyond grass: The case for forage legumes

Alberta producers offer the wisdom of their experience — and their gains — from high legume pastures

If you’re fearful that seeding pasture with legumes will be a waste of time and money, several Alberta producers have some tips for you. A new video from Alberta Agriculture and Forestry features producers offering their advice — some of it hard earned — on topics such as seedbed preparation, nutrients, and weed control. Having […] Read more

A late spring means hurry up and go, but early weed control is 
still critical, says crop specialist Harry Brook.

Weed pressure ramps up in late spring

Weeds that emerge a week before the crop can cause up to 50 per cent yield loss

In a late spring like this one, you might be tempted to skip spraying for weeds to make up for lost time — but that decision could cost you. “The last few years, we’ve had early springs, so people weren’t feeling like they were under the gun,” said Harry Brook, crop specialist with Alberta Agriculture […] Read more


Scouting for weed escapes after spraying allows you to assess both the effectiveness of the application and spot an emerging resistance issue.

Timely and effective field scouting covers many bases

Provincial crops specialist says scouting not 
only pays dividends this year, but allows you to fine-tune practices for future years

Plant density, weed escapes, early signs of disease, and pest populations should all be on your scouting checklist, says a provincial crop specialist. Evaluating the plant population for a given crop lets producers see if the number of plants (per square foot or square metre) matched the target goal that was established at the time […] Read more

Now in its third year, Ag in Motion is Western Canada’s only major outdoor farm show, where you can see, hear and feel the latest in ag technology. It will be held July 18-20 at Langham, just 15 minutes northwest of Saskatoon. For more information or the full program, visit www.aginmotion.ca.

Seeing results where they count

More than 25 companies will showcase their products in more than 100 acres of crop plots

At Ag in Motion, seed, crop protection and fertilizer companies, as well as grower associations and industry members will showcase field crop products as they should be seen — in the ground. Ag in Motion is home to over 100 acres of crop plots from over 25 companies and organizations, with both numbers growing every […] Read more
