To date, AAFC’s Dr. Hugh Beckie has not seen Palmer amaranth in the Prairies. However, he says, 
“if it did come up it would be through the floodwater in the Red River Valley.”

Palmer amaranth continues to spread north

Producers should learn to spot the tall, fast-growing 
weed before it becomes a problem

By
Amaranth is extremely nutrient-rich. It was important to the Aztecs, and is still cultivated in South America and Mexico. It germinates easily, grows rapidly and produces huge numbers of seed. But the crop that sustained the Aztec economy famously wreaked havoc on the American cotton industry, and is now affecting corn and soybean producers in […] Read more

Kochia not confirmed ‘triple resistant’ — yet

Producers should take action against kochia based on threat severity

By
Triple-resistant” kochia — kochia resistant to herbicides in Groups 2, 4 and 9 — hasn’t yet been confirmed in Alberta despite recent media reports, says Hugh Beckie, a weed scientist with Agriculture and Agri-Food Canada. Surveys have turned up two-way resistant kochia, specifically Group 2 plus Group 4, and Group 2 plus Group 9 resistant weeds, but […] Read more

EU chemical agency says glyphosate not carcinogenic

By
Helsinki | Reuters — Glyphosate, the key ingredient in Monsanto’s Roundup herbicide, should not be classified as a substance causing cancer, the European Chemical Agency concluded on Wednesday, potentially paving the way for its licence renewal in the EU. A transatlantic row over possible risks to human health has prompted investigations by congressional committees in […] Read more

Controlling cleavers without quinclorac

With quinclorac off of the herbicide menu, farmers will need to use other tools

By
Last spring, the Western Grains Elevator Association (WGEA) and the Canadian Oilseed Processors Association (COPA) advised growers that they would not accept quinclorac-treated canola grown and harvested in 2016. The reason for this announcement was to make sure that grain shipped to customers in other countries remains in compliance with regards to Maximum Residue Limits […] 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
Researchers found no adverse effect on oat yield with the glyphosate application. In fact, 
they saw a slight yield bump and significantly greater test weight.

Oats not affected by pre-harvest glyphosate

Despite buyers’ concerns, variety and environment have more impact than glyphosate

By
In the spring of 2015, Grain Millers announced they wouldn’t buy oats that had been treated with pre-harvest glyphosate. Christian Willenborg was alarmed. “I was alarmed because I really hadn’t heard of an issue. I hadn’t seen an issue,” said Willenborg, assistant professor at the University of Saskatchewan and editor-in-chief of the Canadian Journal of […] 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
Once you suspect resistance, sending the seed for testing can confirm or allay your fears.

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
