must be taken to coat the under sides of the leaves, for that is 

 where the leaf hopper is usually found. 



The bud moth, which is a small reddish brown worm that 

 bores into the swollen buds, eats out their contents and later 

 attacks the foliage, is usually not troublesome when the regular 

 spraying schedule outlined in this paper is practiced year 

 after year. In orchards where it is especially troublesome it 

 may be necessary to make a special application of arsenate of 

 lead just as the buds begin to expand. In that case about 2| 

 pounds of the powdered arsenate of lead should be used to each 

 50 gallons of water, and an especial effort made to coat the buds 

 with a fine misty spray. Possibly something could be done by 

 adding lead arsenate to the first treatment at the rate of 2^ 

 pounds to 50 gallons. 



Russetting and burning Apples with Spraying Mixtures. 



Some varieties of apples, such as Williams, Ben Davis and 

 Grimes, are easily russeted with lime-sulphur at summer 

 strength. In our experience apples may be russeted by material 

 applied when the buds show pink, and when the petals fall or 

 later. It is suggested that growers who have varieties espe- 

 cially susceptible to russeting and that are rarely troubled with 

 scab use self-boiled lime-sulphur as a substitute for the appli- 

 cations recommended in treatments 2 to 6 inclusive. Further- 

 more, self-boiled lime-sulphur has been found to be very effective 

 in stopping the ravages of the rose bug. 



When lime-sulphur, summer strength, is applied to apples 

 under high temperatures, especially if applied very heavily, it 

 is likely to produce a most serious burning of the apple fruit. 

 This type of burning is one which the apple does not readily 

 outgrow. The writer has seen enormous damage done in this 

 way. It is the writer's experience that Bordeaux mixture, 

 which is sometimes used in place of lime-sulphur in sprays 

 recommended in treatments 2 to 6 inclusive, is very likely to 

 russet and burn in wet weather, while lime-sulphur is very likely 

 to russet and burn in hot dry weather.
