Three fundamental elements to manage weeds

Q & A with an expert

By
Q: What can I do to reduce potential herbicide-resistance issues? A: Driver weed populations on a farm level tend to remain relatively consistent over time. Some species may move into cropland from field edges and pasture lands and others may leave with reduction in tillage. Generally, the weed species that cause most issues on a […] Read more

Keep kochia off your farm

Why kochia is one of Western Canada’s most problematic weeds, plus how to knock herbicide resistance on the head or prevent its development in the first place

By
Prairie farmers are well known for their hospitality but there’s one visitor they want nothing to do with — kochia. Kochia has become one of the most problematic weeds in Western Canada. A single kochia plant can produce up to 25,000 seeds and can achieve a germination rate of 60 per cent or higher depending […] Read more

How to scout for herbicide-resistant weeds

What to look for and when, plus prevention tips and an update on herbicide-resistant downy brome in canola

By
Get out and scout. Next to diversifying your rotations and herbicide selection as much as possible, it’s a critical part of managing herbicide-resistant weeds on your farm in 2022. Scouting is important because without an accurate and thorough picture of what resistant species exist in your fields, you can’t make the best management decisions. More […] Read more
In 2015, Amazone had developed technology capable of identifying weeds in fallow fields and selectively spraying them. Now the company is field testing a sprayer that can identify weeds in a growing crop.

Amazone field tests sprayer with in-crop selective spraying capabilities

By
In 2021, both John Deere and AGCO announced they were developing selective spraying technologies. Deere introduced its See and Spray Select as an option on model year 2022 400 and 600 series sprayers. That system is capable of identifying weeds in fallow fields and selectively spraying them. It’s what the industry now calls “green-on-brown” technology […] Read more

New herbicides for 2022

Options to deal with existing and emerging weed issues and the rising threat of herbicide resistance

By
As notorious yield robbers, weeds have always been one of farmers’ biggest headaches, and swelling herbicide-resistant weed populations have made weeds an even bigger problem. To help producers deal with existing and emerging weeds and the rising resistance threat, new herbicide solutions are released every year. Here’s a look at some new products coming to […] Read more

Crop advisor casebook: Why is this Manitoba field full of pigweed?

A Crop Advisor's Solution from the September 21, 2021 issue of Grainews

By
Lucas farms near Starbuck, Man., growing corn, soybeans, wheat, oats and canola. I received a call from Lucas at the end of June last year. He suspected he had some herbicide efficacy problems, as he noticed some redroot pigweed was not dying after he sprayed a field of corn with Roundup. “It’s been three weeks […] Read more

Your overview of pre- and post-harvest herbicide applications

Q & A with an expert

By
Q: What can I do to control perennial weeds on my farm?  A: Late or end-of-season herbicide applications present growers with an opportunity to gain long-term control over tough-to-kill perennial weed populations.  The main goal of this application should be weed control and not hastening crop maturity. In fields with weed populations composed of quackgrass, […] Read more

Fall herbicide application timing in canola

To control perennial weeds in canola, there are benefits to both pre- and post-harvest control options — the deciding factor could be tied to your goals

By
When deciding between a pre-harvest or post-harvest spray application to control tough perennial weeds, there are always some key considerations for farmers. The extent of the weed problem and harvest timing are important ones, of course, but other factors such as herbicide cost and killing frost also play into the decision. To control a weed […] Read more
To hit up problem weeds, such as herbicide-resistant kochia (far left photo), Alberta farmer Dallas Vert applies a post-harvest weed control treatment of Valtera. Last year, Saskatchewan farmer Dallas Leduc’s post-harvest application of Roundup ProActive 360 tank mixed with four ounces of 2,4-D worked well on Canada thistle (middle photo) and narrow-leaved hawk’s beard (right) on his farm.

Zap troublesome weeds in the fall

Whether it works best pre- or post-harvest depends on several factors

By
A sampling of western Canadian producers, when asked about their fall weed control measures, have most generally agreed that either a pre- or post-harvest herbicide application is a valuable management tool. Most of the farmers contacted leaned toward a post-harvest treatment with a glyphosate product, although there are a number of caveats that come into […] Read more
