Plant stressors that may cause missing pods in canola
By Top Crop Manager
Aug. 20, 2013 - Each year across Western Canada, many producers and agronomists encounter canola crops
with blanks or missing pods on the main stem.
Typically, a missing pod can result from any stress on the plant because stress inhibits proper fertilization of the flowers. According to the Canola Council of Canada, it is important to accurately determine the cause of the
stress in order to take steps to reduce its impact on future crops. In many cases the cause may seem obvious, but it is often a good idea to investigate further to ensure there are no other contributing factors.
The Canola Council has an excellent fact sheet that outlines possible reasons for missing pods. Check it out here: http://canolacouncil.org/media/515806/missing_pods_or_blanks.pdf.
