Grain buyers want you thinking about residues before you harvest

It hasn’t happened yet, but exceeding pesticide residue limits on exported grain could cause a ‘big problem’

By
Grain growers are again being urged to heed the labels on their pre-harvest pesticides and avoid going over maximum residue limits. “We’re selling our crops mostly into export, and our exports markets are very sensitive to residual levels of different crop protection products that we use,” said Alberta Wheat Commission chair Kevin Auch, who farms […] Read more

Managing herbicide resistance

Gowan Canada will host a speaker series 
on Wednesday and Thursday at Ag in Motion

By
Diversity is defined in the dictionary as “the condition of having or being composed of differing elements.” In weed control, diversity means using multiple strategies, or an integrated weed management approach. For herbicides, this means using all of the modes of action available to reduce the risk of weed resistance. This may be obvious, but […] Read more

Tips for wild oat and volunteer canola control

Agronomy tips... from the field

By
Wild oats and volunteer canola are two prevalent weeds that need to be controlled each year. When selecting your wild oat herbicide, be aware of the chemistry groups that you are using throughout your crop rotation. Group 2 herbicides have become a popular choice for wild oat control, but be careful that you’re not overusing […] Read more

Play it safe with pre-harvest glyphosate

Follow the label and consult grain buyers for guidelines

By
When it comes to pre-harvest perennial weed control, Prairie farmers need to play it safe this fall. As of this year, grain from crops treated with glyphosate might have market access concerns, according to the Keeping it Clean program, a joint initiative of the Canola Council of Canada, Cereals Canada and Pulse Canada. “Glyphosate residues […] Read more

Lay the groundwork for a strong soybean season

Agronomy tips... from the field

By
Want to set the stage for a strong soybean crop? Start by seeding into warmer soils. Light tillage can help break up crop residue and spread it evenly across your field. Working up soil also attracts sunlight and heat more effectively. Aim to seed into moisture to give your beans a better start. If possible, […] Read more

New blackleg resistance labels for canola

By
The canola industry has agreed to voluntarily enhance blackleg resistance labels on canola seed. Seed companies will still use the current R, MR, MS, and S labels. But they will also start adding information indicating which major genes are present in a blackleg-resistant variety. Each blackleg-resistant variety leans heavily on a single major gene for […] Read more
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

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
