ChemChina, Syngenta win U.S. antitrust approval for deal

By
Washington | Reuters — The China National Chemical Corp., or ChemChina, has won U.S. antitrust approval to buy Switzerland’s Syngenta on condition that it divest three pesticides, the Federal Trade Commission said on Tuesday. To win approval for the $43 billion deal, the companies agreed to divest ChemChina’s generic production of the herbicide paraquat, the […] Read more

Producers focus on herbicide rotation

Farmers figure it’s better to avoid herbicide resistance than manage around it

By
John Berger and Spencer Hilton are southern Alberta farmers doing all they can as part of their crop and herbicide rotation programs to reduce the risk of weeds developing herbicide resistance. Berger, who along with son Brad, crops about 5,000 acres near Nanton, south of Calgary, actually stockpiled some particularly effective chemistries when Monsanto sold […] Read more
“It’s tempting to spray while it’s calm, but if there’s no wind the droplets will often stay suspended for a while behind the sprayer,” says Dr. Tom Wolf.

Herbicide drift not always wind-based

Spray drift can also happen when it’s calm, and the consequences can be dire

By
As many farmers have found out the hard way, herbicide doesn’t always go where you direct it. “Any time an application of spray is made, there are always small droplets that can move away from the intended target,” said Dr. Tom Wolf, applications specialist with Agrimetrix Research & Training. Generally speaking, herbicide drift is linked […] Read more

Dicamba drift gets real

Will new spray chemistry lower the risk of dicamba drift in 2017?

By
In 2016, so many U.S. farmers spaying dicamba had spray drift problems that the U.S. Environmental Protection Agency released a compliance advisory in August citing “an unusually high number of reports of crop damage that appears related to misuse of herbicides containing the active ingredient dicamba.” The EPA advisory said: “Extension experts across the country […] Read more

Are there resistant weeds in your fields?

The answer to this question is probably yes. Testing can give you a definite answer

By
Every season more farmers face the challenge of herbicide-resistant weeds. “Herbicide resistance is the genetic capacity of a weed population to survive a herbicide treatment that, under normal use conditions, would effectively control that weed population,” said Dr. Jeanette Gaultier, weed specialist with Manitoba Agriculture. It’s sometimes described as evolution happening at an accelerated pace […] Read more
Agriculture Canada researcher Bob Blackshaw, right, with Univeristy of Alberta master’s student Mat Vercaigne talk to producers during a field day in Lethbridge on “forgotten” herbicides that can help manage resistance.

Old, new products deliver multi-modes of action

The challenge is to hit weeds with two or more active ingredients to reduce resistance

By
Old chemistry, new formulations, multiple modes of action — these are all elements farmers can include in their weed control toolbox heading into 2017, say weed researchers and crop protection specialists. One of the most important elements these days for either preventing or managing herbicide resistance in weeds is to approach control with multiple modes […] Read more
Weed researchers are studying several options to control herbicide-resistant weeds. Researchers need to test each product or practice alone, and in combination.

Use diversity to fight resistant weeds

The latest in using integrated weed management tools for hard-to-manage weeds

By
A three-year study in Arkansas has found that a combination of fall management practices and herbicide use are the most effective ways to control herbicide-resistant Palmer amaranth, when combined with a herbicide program. But Arkansas isn’t Alberta. So what can western Canadian farmers learn from this study? More and more often the message in weed […] Read more

Stem Shock: new herbicide in development

A new mode of action based on RNA could soon be killing a weed near you

By
It’s been over 20 years since chemical companies released a new mode of action in herbicides. But a B.C.-based company is cooking up a whole new type of herbicide. “We use a different mode of action for the actual killing of the plants than a lot of traditional herbicides. Most herbicides, by reducing the specific […] Read more

How we make sharing a crucial piece of farm equipment work on our farm

I’m not dead, I’m just married!” These were my words to Grainews editor Leeann when she wondered if I was writing another column anytime soon. That was several weeks ago. Being married and also farming in two different locations has certainly blown my hair back these last several months. The logistical challenges, not to mention […] Read more
