Rapeseed has strong moisture resistance. Excessive soil moisture in a short time after drowning in the field does not generally cause serious yellowing of leaf color. Severe yellowing of rapeseed leaves should be considered whether it is affected by herbicides from previous crops. It is recommended to further inspect the rape root system. If the root growth is basically normal, only the leaves are slightly yellow, you can continue to observe for a period of time, and you do not need to rush to destroy the seed. If the root system is dark and there are few root hairs, further investigations should be conducted and countermeasures taken.
