SPRAYING FOR APPLES. 



To give a good all-round protection requires from three to five spray- 

 ings each season, as follows : 



1. Winter Spraying. — Use Commercial Lime-sulphur Wash at rate of 

 1 gallon to 8 or 10 gallons of water (see page 19), or, if you prefer, you 

 may make your own Lime-sulphur Wash at strength of 15 pounds lime, 

 15 pounds of sulphur, to 50 gallon? water (see p. 19, or pp. 33 and 34). 



This winter treatment is especially for San Jose Scale. If this pest 

 is not troubling you, you need not use this treatment every year; but 

 it has such a good general effect on the trees that it is best to use it 

 every few years anyway — and it is important for those who have San 

 Jose Scale to use it every year. 



2. Just Before Flower-buds Open. — Use Commercial Lime-sulphur at 

 rate of ly^ gallons to 50 gallons water and add 3 pounds of Arsenate of 

 Lead Paste. (See pages 33 and 34.) 



We do not regard this treatment as absolutely necessary, but it does 

 good and will pay if one can get it done. It checks the very earliest 

 caterpillars and diseases which attack young leaves and flowers. But 

 if one gives the winter spraying already described and gives the treat- 

 ment just after blossoms fall, it will seldom be really urgent to give this 

 one. If you must omit any of the sprayings let it be this one, as we 

 regard it as the least important. This is often called the "Cluster-bud 

 Spray." 



3. Just After Blossoms Fall, Promptly. — Use Commercial Lime-sulphur 

 IV2 gallons to 50 gallmis water and add 3 pounds Arsenate of Lead Paste. 

 (See pages 33 and 34.) 



This is the most important spraying of all for the fruit, and should 

 never be neglected in bearing orchards. Its special object is to kill the 

 Codling Moth which makes the "wormy apple," and as the worm usually 

 enters at the blossom end we must spray promptly after the blossoms 

 fall, as the blossom end is then open and will receive the poison. All 

 the trees will not shed the blossoms at the same time, so we must strike 

 at the best time for the average, or for the ones we prize most, and every 

 effort must be made to lodge some of the spray in the open blossom end 

 of each young apple. 



4. Three to Four Weeks Later. — Use the Bordeaux Mixture at rate of 

 Jf. pounds Lime, 3 pounds Bluestone, 50 gallons water, and add 3 pounds 

 of Arsenate of Lead Paste. (See pages 34 and 35.) 



This treatment, coming three or four weeks after the blossoms have 

 fallen, will be when the apples are about an inch in diameter, more or 

 less. It will reach some Codling Moth which escaped the third treatment 

 and will catch caterpillars which may have started since. As the leaves 

 will be nearly grown, this treatment will usually benefit them for the 

 rest of the season. It also protects the fruit considerably from rots which 

 attack it later in the season.
