The latest estimates are that as much as 50 per cent of the crop area in Western Canada could be affected by Group 1- and/or Group 2-resistant wild oats.

Ag in Motion: Managing herbicide resistance

Diversity is defined in the dictionary as “the condition of having or being composed of differing elements.” In weed control, diversity means using multiple strategies, or an integrated weed management approach. For herbicides, this means using all of the modes of action available to reduce the risk of weed resistance. This may be obvious, but

Seeding nearly complete at 90 per cent, Northwest areas slowed by wet conditions

Manitoba Crop Report and Crop Weather report for May 29, 2017

Moderate to cooler than normal temperatures last week. Strong southerly winds on Wednesday caused soil blowing and drifting on soils with dry topsoil and poor crop residue. Low to moderate rainfall amounts reported in most regions with the highest precipitation in the North West where some fields are excessively wet and will require days of

Mustard acres feeling squeeze from canola

CNS Canada –– Following the largest mustard crop in more than a decade in 2016, supply/demand fundamentals are expected to spur a reduction in Canadian mustard seedings in 2017. However, with more and more cropland moving into canola, mustard acreage increases may be limited in future years when supplies are tight again. After growing the

Glyphosate-resistant kochia is the latest warning sign for Manitoba farmers.

Herbicide resistance quietly growing problem in Manitoba

Multi-pronged weed control strategies that go beyond chemicals are urged by researchers

Farmers may lose the war against herbicide-resistant weeds if they don’t start using other forms of control besides chemicals, a University of Manitoba weed scientist says. Herbicide resistance, common in other countries, is starting to appear in Western Canada and it’s just a matter of time before it becomes prevalent here too, Rob Gulden warns.


Sandblasting might be a way to kill weeds and leave crops unharmed, lowering the environmental impact of weed control measures and giving organic growers other options.

Abrasive weeding mechanically controls weeds without tillage

A Minnesota-based USDA agronomist had the idea 
after a bumper apricot crop

A new research project in the U.S. Midwest aims to blast weeds away — literally. The technique is known as abrasive weeding and it basically amounts to sandblasting weeds. It all started when Minnesota experienced a bumper crop of backyard apricots in 2007. Frank Forcella, a USDA weed scientist and agronomist, was left with a

How to fall apply Avadex and Fortress

Getting the application technique right will make these products more effective

Apply Avadex and Fortress in the fall after the surface soil temperature is below 4 C and within three weeks of soil freeze-up. This situation generally occurs by October 1 across Western Canada. A single heavy harrow pass is sufficient for incorporation in minimum- and zero-till fields. Good soil contact is necessary for these herbicides


Editorial: Peace and prosperity

Maybe it’s time for agriculture to climb down from its wartime footing. For decades now it’s been a battle as farmers fight nature, red in tooth and claw, to prevent crop damages and loss. It’s hardly surprising when you consider the historical context out of which our modern Green Revolution agriculture sprang. It took off

Clubroot figured out canola in Alberta. Then it began destroying canola.

Editorial: Long-term plans essential

The farms that are winners tomorrow will be run by farmers who are proactively understanding and defusing production problems today. There are a number of growing issues that could be a disaster tomorrow, but growers can prevent them if they’re committed to doing the right thing now. The best example, and the one that’s a


Monsanto aims to give farmers better information in weed resistance fight

Monsanto aims to give farmers better information in weed resistance fight

The company is countering its competitors who tout their herbicides 
as tools in the fight to avoid herbicide-tolerant weeds

Monsanto Canada is fighting what it says is “fear-based rhetoric floating around about farming practices and (weed) resistance in Canada.” In a recent full-page advertisement in several farm newspapers, including the Manitoba Co-operator, Michiel De Jongh, Monsanto Canada’s president and general manager, said Monsanto should’ve addressed herbicide-resistant weeds sooner. “When you began to battle herbicide

Weeds are more obvious when looking at a wheat crop down (r) than looking at it sideways, says Manitoba Department of Agriculture weed specialist Jeanette Gaultier.

Recent rains help crops and weeds

Herbicide-resistant weeds make controlling weeds even harder

Most Manitoba farmers needed the rain, but wet fields have delayed weed spraying, says Manitoba Department of Agriculture weed specialist Jeanette Gaultier. Dry soils delay weed emergence, but the recent rains and warmer weather have triggered germination, creating a green carpet of weeds in some fields. “The crop is going to pop, but so are
