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……

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…

Usually the best response to a light frost is to leave the crop standing to mature fully and continue to clear green…

This has been a common question after last week’s heavy frost. Growers wonder whether frost-damaged canola should be swathed or left standing for straight combining. By now, any pod splitting or pod drop due to tissue damage from the heavy frost has probably happened. This usually starts within a day of the frost event. If the crop is still sound,…

With light frost in the forecast, crop left standing will still have a chance to mature further and yield more. A heavy frost will lock in high green counts and likely increase yield loss with pod splitting and pod drop. Swathing before the heavy frost event may prevent this green lock, but the crop needs to dry down to a…

Frost on pods can stop plant development and lock in green. It can also cause pods to split. However, a light frost may have no effect at all, and the crop will be better left to mature fully. To determine which situation applies in a frost situation, do the following…

Check standing canola the morning after a frost, but wait at least 4-6 hours after frost to allow the full extent of severe frost damage to become evident. The crop may look undamaged that morning but by lunch time, wilting, desiccation and pod splitting may begin. If you scout early and then not again, you may underestimate the damage and…
