These five questions are based on content from the handy crop protection guides from Manitoba, Saskatchewan and Alberta. Manitoba and Saskatchewan guides are the same with different covers. Alberta has its own, often called the “Blue Book” Here are links to online posting for all three:
With hot, dry conditions, canola seedlings already under pressure from intense flea beetle feeding dried out and died.
The Canola Council of Canada agronomy team looked at this photo above and discussed whether the field should be sprayed now or in a few days after more weeds have emerged. Consensus was that the field could have been sprayed a few days earlier. Angela Brackenreed, who scouted the field, says the weeds just became visible in the past three days, so the crop is actually well ahead of them. She confirmed that the grower plans to spray today as long as conditions allow.
Weeds are coming up strong. As part of the Canola Council of Canada’s Keep It Clean campaign, we remind growers to use only registered pesticides when required. Refer to product labels for proper use instructions. Here are strategies to improve weed control results for each HT system: Clearfield Group 2 products for the Clearfield system […]
Tank mixes used for pre-seed burnoff ahead of cereals often contain Group 2 and Group 14 products that can hang up in sprayer plumbing. These residues can be particularly damaging to canola.
Common canola-crop herbicides and surfactants left in a tank for any extended period of time are very good at removing these residue deposits from tank walls and sprayer plumbing, causing them to mix in with the spray solution. If wind or rain delays spraying, the concentration of scrubbed-free herbicide residue in the tank can continue to increase.

Western Canada has a short growing season. Crops in Western Canada start to take up nutrients early and uptake escalates quickly. For these reasons, the ideal timing for fertilizer application is at seeding. This saves an extra pass over the field and ensures that the expected fertilizer requirement is in place when the crop needs it. But there are times when an in-crop top up of nitrogen or sulphur makes sense.
In one case this year, a grower seeded 2.2-gram thousand seed weight (TSW) canola seed at 5 lb./ac. With very good seed survival due to warm, moist soils, the crop now has 20 plants per square foot. Is the intense competition between these crowded plants likely to result in lower yields?
What to do about crusting? Gophers. Herbicide injury. Keep It Clean. And more…
The “Windy” app for iPhone and Android and wind speed, gust and direction information at will back up what you already observed outside the sprayer cab…that it’s too windy for spraying, again. So how do you spray weeds in a timely fashion when every day seems too windy?
