Frost hits standing canola: What to do?

Check standing canola the morning after a frost, but wait at least four 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 miss a chance to swath now to save some of the yield. Conversely, light to moderate frost damage may take longer to become evident, so scout again after two to three days to reassess and make a decision.
