“When you’re looking at the sprayer, how it’s physically put together in terms of the structure and how it’s operated, we want to understand how that impacts the potential for spray drift.” – Lorne Grieger , PAMI.

The aerodynamics of crop spraying

Air disturbance from the sprayer itself may be affecting your drift risk

By
We’ve come a long way with sprayers. We’ve made them bigger, we’ve made them faster and with new visual technology and artificial intelligence, we’ve even made them smarter. Now, research by the Prairie Agricultural Machinery Institute (PAMI) along with the College of Agriculture at the University of Saskatchewan and Agrimetrix in Saskatoon is asking, ‘Can
Growers need to understand their seed technologies and the weed spectrum they’re dealing with.

Keeping your herbicides on target

Herbicide resistance, seed technologies add complexity to spray decisions

By
Glacier FarmMedia – Off-target movement of herbicides carries a risk to your crops, the neighbour’s crop and insurance premiums. With the arrival of Group 4 and Group 9 herbicide technologies, growers may think weed management is simpler. But resistant weed biotypes confound that notion and challenge growers and their advisors with tank-mix solutions and application

French court bans sale of two Touchdown glyphosates

Court cites lack of analysis of effects on wildlife

By ,
Paris | Reuters — A French court has banned the sale of two glyphosate-based herbicides produced by Swiss chemical group Syngenta because of a lack of analysis on the chemical’s potential harm to some wildlife. “The decision on Sept. 30, 2020 by French health security agency ANSES to renew the marketing authorization for the chemical

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.
“You need to make every drop of the herbicides count while they’re still working.” – Kim Brown-Livingston.

Herbicide resistance can’t be ignored

A weed control strategy will encompass the entire production system

By
Herbicide resistant weeds have been present in Manitoba since the 1980s but they are now becoming a critical issue that cannot be ignored. Kim Brown-Livingston, Manitoba Agriculture’s weed specialist, called it the biggest problem facing producers. More resistance is cropping up and no new modes of action have been available on the Prairies in the

The case for integrated weed management

Research scientist Charles Geddes says having the right agronomic strategy is key to combating herbicide resistance

Weed control can’t count on knockout punch

The chemical control era is waning, so adoption of new combinations is very important

By
Herbicides have been the No. 1 weapon against weeds since the 1940s. They’ve been effective but the last few decades have shown that genetics are a more powerful force than chemistry. Weeds are gaining genetic resistance to herbicides faster than new chemistries can be developed. “In addition to all of these new cases we’re seeing,

Bayer sued for barring non-U.S. citizen from Roundup settlement

By
Reuters – A new U.S. lawsuit accuses Bayer of illegally excluding a Virginia farm worker from a settlement over claims its Roundup herbicide causes cancer because she is not a U.S. citizen.
