Canola can lose flowers to many stresses, including insects, heat, heavy rain, and late herbicide application. Canola plants that lose flowers can recover without a yield penalty — or not much of one — if conditions improve by early to mid flower. The chart above shows that canola plants produce far more flowers than pods, providing a cushion to compensate for flower loss early. The plant can utilize the later flowers if needed. If not needed, these late flowers won’t likely amount to much.

Canola can recover from hail up to 20% flower
Canola hit with light hail at up to 20% flower may recover with only minimal to moderate yield loss. Plants will flower longer and compensate. However, canola that flowers longer…
