In Alberta, kochia patches could form in new parts of the field or neighbouring fields where tumbleweeds may have blown, says AAFC’s Shaun Sharpe. Approaches and compacted areas may also be potential areas of invasion and spread as well as along roadsides, grid roads and field margins and around sloughs. Weed specialist Clark Brenzil highly recommends preventing the growth of kochia by planting perennial forages in ditches and even in saline (or otherwise non-productive) areas in fields.

Weed issues to watch in 2022

How different factors, such as moisture, temperature, herbicide resistance and others, may affect weed populations this year

By
After a series of dry years on the Prairies — with 2021 being driest of all — the provincial weed outlook for 2022 is varied across Western Canada and field to field. From kochia invading new territory to a possible increase of overwintering weeds — such as later-emerging false cleavers, Canada thistle, shepherd’s purse and […] Read more
A herbicide layering strategy uses a pre-seed treatment on emerged weeds while using soil-applied products simultaneously to control weeds that emerge a couple of weeks after the initial application. The pre-seed treatment helps to remove early-emerged weed pressure while the soil-applied application, when activated by moisture, provides extended control to help reduce weed pressure prior to the application of an in-crop herbicide. This type of strategy not only helps with early weed removal and allowing the crop to establish and take advantage of the nutrients and moisture available, but it also provides farmers more options for an in-crop application that will best target the later-emerging weeds that have to be dealt with.

Take a layered approach to herbicides

Develop an effective herbicide layering strategy — it could be one of your most powerful tools in the fight against herbicide resistance

By
It’s no secret that herbicide-resistant weeds are making life increasingly difficult for many crop growers in Western Canada, but the situation is far from hopeless, says an agricultural expert. Canada currently ranks third in the world for herbicide-resistant weeds, trailing only the United States and Australia in that category. Studies have shown there are currently […] Read more

Syngenta releases new grass and broadleaf cereal herbicide

Farmers can address herbicide resistance concerns and avoid rotational crop restrictions with Erebus Xtreme

By
For Prairie farmers battling problem weeds, herbicide-resistant wild oats are one of the worst as they’re now found throughout Western Canada. One of the best ways to combat herbicide resistance is to rotate active ingredients, which is why Syngenta has introduced Erebus Xtreme, a new cross-spectrum herbicide aimed at helping cereal growers control herbicide-resistant wild […] Read more

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
Among the most serious weed resistance concerns on the Prairies are wild oat and green foxtail, both seen here in this photo from Manitoba’s Interlake region in 2020.

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

Tips to conserve soil moisture and manage weeds this spring

Plus, where tillage fits in and how and when it could be used

By
Although it has only been on most farmers’ radars for the last couple of decades, no-till production has become a modern-day success story, with well over half of Canadian farmland now being farmed under its practices. However, no till relies heavily on herbicides to manage weeds and retain soil moisture. And with key herbicides like […] Read more

Anticipate herbicide damage

After a very dry year followed by a cold winter, watch for residual herbicides

By
Last year, it was very dry over much of the Prairies. Your lower-than-expected yields have got you calculating how much nutrients/fertilizer are left in your grain or oilseed fields. Also to consider is how much herbicide residue is left in some of your fields. What crops do you intend seeding this spring? Canola, perhaps, due […] 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: Has herbicide injury damaged 60 acres of lentils?

A Crop Advisor's Solution from the August 24, 2021 issue of Grainews

By
Charles farms in Elrose, Sask., where he runs a 4,500-acre mixed grain farming operation, which includes lentils. He called me one day and said one of his 320-acre lentil fields had taken a turn for the worse. Approximately 60 acres of the field showed what he thought looked like significant herbicide injury, while the other […] Read more
