Does the early weed controller always get the worm?

Q & A with Nutrien Ag Solutions

By
Q: Is early weed control always a solid tactic? A. It’s been well established that competition from early-emerging weeds is most detrimental to crop development. Weeds emerging along with the crop compete for moisture, fertility and light before the crop has a chance to get the upper hand by developing its root system and getting […] Read more

Managing Saskatchewan’s toughest weeds

You’ve seen these weeds before, and you’ll probably see them again


By
No matter which crops Saskatchewan farmers grow, the same weeds appear year after year. While the culprits are consistent, how you manage them is not, especially as herbicide resistance cases mount. For nearly 50 years, Canada thistle, wild oats, wild buckwheat and green foxtail have appeared in the top-five list of problematic weeds in Saskatchewan. […] Read more

Herbicide carryover may be high risk

If it was dry after last year’s application, there may be soil-residual herbicides

By
Crop selection for the 2019 growing season could prove challenging for growers in some parts of the Prairies, as a lack of rainfall means soil-residual herbicides could impact crop establishment. Moisture after application is critical for herbicide breakdown. In areas where rainfall was patchy at best, growers need to be conservative when selecting crops to […] Read more

Residual herbicide and crop injury

When the worst happens: what questions to ask and how to soil test for a bioassay

By
Your cereal, oil seed or legume crop clearly shows that it has been significantly damaged by herbicide application or residual herbicide that was applied to cropland one or more years previously. You are considering possible legal action. What do you do next? First of all, you just don’t take a few photographs, complain about significantly […] Read more

Get back to basics to fight kochia

Using multiple and rotating modes of action can reduce selection pressure

By
In recent years, kochia has become a real issue across the Prairies. Kochia loves hot, dry weather, and as a prolific seed producer, the tumbleweed-shaped weed can spread quickly. What’s worse, kochia has a growing history of resistance, which can make it a tricky weed to manage. Agriculture and Agri-Food Canada research scientist Charles Geddes […] Read more

Avoiding herbicide mis-use

Herbicides have made it easier to feed the world, but beware of residuals and improper use

By
Herbicides are an integral and essential aspect of modern productive farming. Without our effective and efficient herbicides our dollar costs for food production would be double or triple what we now pay. Can your even visualize hand weeding agricultural and horticultural crops? As a youth I earned pocket money hand hoeing turnips and beets and […] Read more

Bourgault Tillage Tools debuts a new weed control option

One of the newest implements to hit the market in Canada this year, the Weed Clipper (video), came from Bourgault Tillage Tools, and it was on display in the Innovations Show Place at Canada’s Farm Progress in Regina in June. Designed to cut fast growing weeds that are taller than the crop, the Weed Clipper gives […] Read more

Herbicide diversity tackles kochia

As the weed works hard to outmanoeuvre chemicals, farmers expand the toolbox

By
Joe Wurz takes kochia control seriously. The southern Alberta farmer at the Lathom Hutterite Colony takes all weeds seriously, but a few years ago when he observed some healthy-looking kochia plants standing in a patch of dead kochia on farm fields near Brooks — all had been sprayed with glyphosate — he suspected herbicide tolerance […] Read more

Extending rotations, in the field

Part 1 of 3: How real farmers are extending their rotations

By
There seems to be no shortage of articles, presentations and research exhorting farmers to lengthen rotations. Longer rotations benefit everything from weed control to disease suppression in crops. But what are farmers doing to maintain or extend rotations? Grainews spoke to three farmers to find out how they’re managing their rotations. And while each farmer […] Read more

Reporter’s Notebook: How will we be farming in 20 years?

Lisa Guenther points to two agronomic problems shaping our future cropping plans

By
Agriculture has undergone big changes in the last century. Yesterday’s farmers would be amazed by the technology contained in a tractor and seeder these days, or by the vaccines that protect livestock from disease. Or even by the phones we tuck into our back pockets, and occasionally drop in the muck. It’s an interesting exercise […] Read more
