Is the water in your sprayer neutering your herbicide?

Calcium, magnesium, sodium, iron and potassium cations in sprayer water will bond with herbicide molecules, such as glyphosate, making them ineffective

Clint Jurke had never, not once, tested the quality of his sprayer water until a colleague said it would make a good topic for an article. “I like to think I’m pretty good at agronomy,” said Jurke, agronomy director for the Canola Council of Canada and farmer from Lloydminster, Sask. “I scout, follow labels’ rates,

What’s on your spring burnoff checklist?

Set yourself, and your crop, up for success from the get-go

By
It’s been a long, cool spring and farmers have had extra time for field preparations. Sprayers and seeders are poised and ready for action and, when the temperature hits growing degrees, everything will happen fast. The first happening should be the spring burn-off. “I’m a big fan of burn-off spraying,” said Manitoba Agriculture weed specialist

Weed wave expected when warm weather returns

Once it warms up, it’s going to be important to get a good spring burnoff and establish a competitive crop

By
Unseasonal snowfall and a cool spring may have pushed thoughts of spring weed control down the list of things to think about. But it’s important to get a plan in place now, because when it does warm up, things will happen quickly, said Kim Brown-Livingston, Manitoba’s provincial weed specialist, during an April 19 CropTalk webinar.

Late harvest hampers fall weed control efforts

Narrow regrowth window, cooling temperatures play role in limiting applications

By
Manitoba’s weed specialist says this year’s late harvest has thrown a wrench into many farmers’ fall control plans. Normally, it is recommended that farmers wait four to six weeks after harvest to allow weed regrowth before spraying. “This year, we just don’t have the calendar days to do that,” said Kim Brown-Livingston, Manitoba Agriculture and

Glacier FarmMedia – A plot of white beans at Agriculture and Agri-food Canada’s (AAFC) Harrow, Ont. research farm is part of a new four-site study taking a sandblasting-style approach to weed control in Canadian crops. “No, it’s not a joke,” begins a news release from the federal agriculture ministry about the research into what’s being

Old invention shows promise for weed control in potatoes

Originally designed for insect larvae, the potato vine crusher lowers germination rate of weed seeds

By
An invention originally designed to control European corn borer in potatoes has shown potential to reduce weed seeds during potato harvest. Dr. Andrew McKenzie-Gopsill, a research scientist with Agriculture and Agri-Food Canada, recently discussed the advantages of minimizing weed seeds during harvest to reduce pressure in potato crops. Then a colleague suggested an invention that

Add the weather forecast into your calculations when planning fall weed control. It’s prime weed control season for perennial weeds like Canada thistle and winter annuals and acting now can help you, come spring. “A lot of the winter annuals are starting to become problems because if we don’t do any kind of control in

Now’s the time to find resistant weeds

Herbicide-resistant weeds are on the rise and pre-harvest is a good time to find them

Delaying the onset of herbicide-resistant weeds isn’t a lost cause. In fact the more vigilant a farmer is the more success they’ll have, says Ingrid Kristjanson, a farm production extension specialist with Manitoba Agriculture and Resource Development (MARD). With farmers checking crop maturity as harvest grows near, it is also a good time to scout

Spring weeds rise up well ahead of seeding efforts

Weed forecasts have farmers expecting to reap the consequences of last year’s lack of field work

By
Farmers are gearing up for spring seeding, but the weeds have already made it to the field. Manitoba’s provincial weed specialist, Tammy Jones, says producers are already starting from behind on weed control this year, thanks in large part to harvest conditions last fall. Why it matters: Seeding is stressful enough as is, but farmers

Field work gap means spring shifts for organic growers

Organic farmers are starting from behind this spring after little field work got done last fall

By
Organic farmers are gearing up for a more complicated start to the growing season after missing much of their field work last fall. Last year’s “harvest from hell” is still sending shocks through Manitoba operations, with wet weather leaving many farmers with unharvested acres and incomplete fertilizer applications. For the organic sector, that same delay
