Owing to the fact that the entire developing apple cannot be completely covered with spray, and thereby given complete protection, until the young fruits have separated in the clusters, this spray should be delayed until they sufTiciently develop. In large orchards, however, it will not be possible to wait until all of the spurs are in this condition. The orchardist should arrange his spraying so that the greatest proportion of the crop is sprayed while in this condition. If mildew is severe add the iron sulphide mixture. 4. Calyx Spray. All orchardists are familiar with the value of applying arsenate of lead at this period in the devolpment of the young apple. Apply the spray a few days following the dropping of the petals. Owing to the fact that it is necessary to protect the fruit from further scab infection, lime- sulphur must be used. In orchards where mildew control is a problem, continue the use of the iron sulphide mixture. 5. Ten-Day Spray. The so-called ten- day or two-weeks spray is primarily used for furthering scab protection. It is through the use of this application and the following one that "shot fun- gus" or the appearance of numerous scab spots on the fruit, usually early in July, is prevented. It is a very impor- tant spray during most seasons and must not be omitted. 6. Thirty-Day Spray. This applica- tion is made just previous to the hatch- ing of the first brood of codling moth and is therefore a very important appli- cation. During certain seasons it is necessary to use a spray in order to prevent further scab development. The use of lime-sulphur is dangerous at this time, due to the possibility of burning, and before using it consult with the nearest investigator. We have been ex- perimenting for two seasons with self- boiled lime-sulphur in this application and t
