Feds back autonomous weederbot’s Halifax manufacturer

ACOA funding to support field-level trials

The federal government’s economic development agency for Atlantic Canada is putting up money for a new round of on-the-ground tests of a self-guided field-weeding robot. Halifax MP Andy Fillmore on Wednesday announced a $550,000 repayable investment from the Atlantic Canada Opportunities Agency’s (ACOA) Regional Economic Growth Through Innovation program for Halifax-based Nexus Robotics. Nexus, the

University of Manitoba researchers Mario Tenuta, Don Flaten and Xiaopeng Gao, along with provincial soil fertility specialist John Heard, were at the field tour site July 23 to answer questions.

Self-guided 4R tour brings new research in era of COVID-19

Through video, University of Manitoba researchers presented new research on increasing nitrogen use efficiency in grain corn

Soil fertility specialists from the University of Manitoba brought the latest “4R” research to the public while keeping a healthy distance, thanks to an innovative self-guided field tour July 23-25 near Carman. “The beauty of a self-guided tour is that people can do it at their leisure,” soil ecology professor, Mario Tenuta told the Manitoba


Delivering equipment demos directly to farmers from the field

Ag in Motion Special Event Feature

From air seeders to UTVs, Ag in Motion Discovery Plus promises to give farmers a chance to check out the latest equipment options from the comfort of their home or office. “Our digital event will deliver a variety of equipment demonstrations directly to farmers from the field,” says Rob O’Connor, Ag in Motion show director.

Fields north of Brandon still show significant standing water and the first hints of crop damage a week after rainfalls that locals counted in the inches.

Sky high demand for aerial sprayers after flood

A significant number of producers were calling in air strikes after 200 millimetres of rain kept their own sprayers out of the field

The same storms that put parts of Westman underwater early this month also had aerial applicators scrambling to keep up with demand. Planes from Westman Aerial Spraying had little downtime in early July. Barry Cooper, business to business operations manager with Heritage Co-op, says they have seen more demand than there are planes available to

Weather conditions that can volatilize dicamba herbicide

Avoid applying all herbicides during temperature inversions too

In addition to drift caused by wind the herbicide dicamba can end up off target due to volatilization, also referred to as vapour drift, and temperature inversions. Last week’s stories on dicamba (see ‘Related Articles’ below) prompted a reader to ask about the weather conditions for both. The University Minnesota explains it on its website

Canadian, U.S. farmers diverge on dicamba spray issues

While U.S. farmers have been devastated by dicamba drift, it’s been a non-issue in Canada

Canadian farmers haven’t experienced the same dicamba drift debacle their U.S. neighbours have — but that doesn’t mean they won’t also pay a price for this high-profile failure. Spray expert Tom Wolf says a cooler climate and differences in the way the product is used here have spared Canada the worst immediate effects. The bill

Dicamba spray drift declining in Canada

The climate and how the herbicide is used here both are factors

There haven’t been many dicamba drift complaints in Canada since Monsanto commercialized dicamba-resistant soybeans in 2016. In 2019 Health Canada received just “16 reports of dicamba-related environment incidents in Canada related to drift and over-the-top application of dicamba to soybean,” a Health Canada official wrote in an email June 10. Health Canada, which regulates pesticides in Canada through the

Precautions to take when applying dicamba

The best way to avoid dicamba drift is to follow label directions. Although dicamba can be applied to Xtend soybeans from pre-emergence to early flowering, applying pre-emergence has advantages. One is if your crop isn’t up, your neighbour’s might not be either and can’t be damaged by drift. “Dicamba provides residual control for a short


Windy weather puts the brakes on spraying

A delayed spring left less room for pre-seed herbicide. Then the wind picked up

High winds may have left producers with bigger weeds than they would like. Winds were enough to cause some sandblasting damage in Manitoba’s young crops in late May and early June. Weather stations in Carman reported wind gusts near or above 50 kilometres an hour in the first two weeks of June, with some days clocking gusts of

Breaking down the recirculating sprayer boom

Non-profit Sprayers 101 demonstrates the concept and benefits of a recirculating sprayer system

Looking at the back of a modern sprayer the pile of hoses and valves in a traditional plumbing system can seem complicated, and even more so when you start to look at recirculating sprayer booms. Hoping to mitigate that confusion, Dr. Tom Wolf and Dr. Jason Deveau have “Everything you never wanted to know about
