That the scab starts early is also well known, and fruits may be attacked before the blossom stage is past. The sprayings with Bordeaux or cupram should begin early and be timed as for the leaf blight above mentioned. Some varieties are more susceptible than others, and in the setting of orchards the selection should be miade with this in mind.
