Three concepts to consider while setting the combine this harvest: (1) Can dockage be too low? (2) Change combine settings based on crop conditions. (3) Frost damaged seed might not be a total write off.
Reseeding looked like the right idea in many areas throughout the summer, but the real test is at harvest. If there was no risk of frost and the significant loss of grade and yield that results, we’d have a lot more canola go in after the soils reached 10°C and the spring frost risk was […]
Harvest is a great time to assess the incidence and severity of canola diseases, an important step in management for next year. Post-swathing disease scouting is possible but results are not as accurate as pre-swath scouting.
Yes, keep going. The recommendation to wait at least 4-6 hours after a frost to assess the extent of frost damage only applies to canola that was not quite ready to swath. If you were already swathing or were going to swath a crop that day, there is no benefit to waiting.
Have you seen patterns like this? Potassium in swathed crop is mobile and if several rainfall events fall on the swath before combining, potassium will bleed out below the swath. Since a six-foot swath contains all the straw from a 30-foot or wider cut, the K is concentrated. K-loving crops following canola can find sufficient K below the swath, but inadequate between swaths.
Moist conditions mean more soil clinging to machinery wheels. This increases the risk of moving clubroot as well as weed seeds and insect pupae around the farm. With the discovery of a potential new clubroot pathotype, growers will want to take time to sanitize equipment between fields.
Storage risk is reduced significantly when canola moisture is 8% or lower and temperature is 15°C or lower. Turn on the fans to cool that hot canola.
Good residue management in the fall will help enhance drill performance, allowing for increased seed survival and an overall better field uniformity in the spring. Changing the angle of vanes on the back of the chopper will help with the width and uniformity of residue spread.

Fall is a good time to control perennial and winter annual weeds. The message this week includes two reminders: Wait for post-harvest regrowth. And know the best timing for the weeds present. The photo shows narrow-leaved hawk’s-beard.
Take these steps to control fall weeds and avoid herbicide carryover damage in fields planned for canola in 2015…
The onset of lower temperatures and shortened days in the fall trigger perennials such as Canada thistle, dandelion and quack grass to start moving sugars to below-ground tissues. Winter annuals and biennial are also doing this, but they don’t need a temperature trigger. Spraying these weeds in fall takes advantage of this downward flow into the below ground buds on the crown or creeping roots of perennials, providing better control for next year.
