lbs. copper sulphate, 6 lbs. lime and 50 gals, water) for the first 

 spraying, arsenate of lead (3 lbs.) being employed with the Bor- 

 deaux mixture (same proportions as above) for the second spraying. 

 The spraying apparatus was faulty, and the trees Avere not 

 sprayed nearly as thoroughly each time as they should have been, 

 yet comparatively good results were obtained. In 1907, when no 

 spraying was done, this fruit grower had a small crop of apples, 

 and even what he had were very badly marked \\'ith the curculio 

 and scab, but this year over two thousand bushels of good clean 

 apples were picked, the orchardist receiving an average of over a 

 dollar per bushel for them. 



SUMMARY. 



1. Spraying plum trees with Arsenate of Lead and Bordeaux Mix- 



ture (3-4-50) two or three times at beginning of Curculio 

 season, at intervals of a week or ten days will prevent at 

 least 509( loss of fruit from Curculio injury, to which must 

 be added whatever injury from fungi is saved by the use 

 of Bordeaux mixture. 



2. Spraying apple trees at the same time will, as our experiments 



and the experiments of others show, control not only the 

 Curculio on the apple, but the Codling Moth as well. 



3. The spraying before the blossoms open gives a result decidedly 



in favor of such spraying. If, however, only two sprayings 

 can be given, the second (May 27th in 1908), and third (June 

 4th in 1908) are the most effective. 



4. Cultivation during July and August, or turning hogs in to gather 



up windfalls is an effective method of control.
