The later hail occurs in the season, the more damage it can do to yield. While canola can keep flowering to compensate from hail that occurs during flowering, hail at the late pod stage can result in unrecoverable yield loss. (The damage to the pod in this photo is minor but could still affect yield if seeds are damaged or…

1. Green and bendable canola stems can often straighten up again (somewhat) if lodged due to wind and heavy rain. 2. If lodged due to disease, these plants are unlikely to straighten up. Plants lodged this early due to disease usually contribute little to yield once harvest rolls around. 3. Lodged plants can be more susceptible to spread of sclerotinia…

Does rain at flowering change the sclerotinia risk and economic return from a fungicide? It could if (1) it results in a dramatic increase in yield potential, (2) if it……

Small amounts of spores can lead to yield-robbing levels of sclerotinia in continued moist conditions. A petal test to confirm the presence of sclerotinia DNA on petals could be used to provide an indication of pathogen pressure at the time of petal collection…

Grasshoppers can thrive in hot weather. The nominal threshold for grasshoppers in canola is 7-12 per square meter, with the low end more appropriate in dry conditions…

In light hail, canola can sometime over-compensate and produce even higher yield. In serious hail situations where entire flowering branches are knocked off, plants that are still actively flowering can produce new branches. This will set back maturity, but with enough season left, these new branches can produce a decent yield…
