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

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.

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
