Treatment of Apple-scab or Mildew.

For these diseases at least four sprayings are necessary, and in case of a wet season two additional sprayings are advisable. The early sprayings—say, the first three—may be the Bordeaux mixture, and as the fruit grows large the latter sprayings had better be the ammonio-carbonate solution. The first treatment should take place just before the flowers open, the second when the blossom falls, the third and following sprayings at intervals of a fortnight; in case of fine calm weather longer intervals may elapse. The finest possible spray, just sufficient to dampen the leaves and fruit, is the proper treatment.
