teed on apples, damaging sometimes as much as 50 per cent, by 

 biting long, narrow, irregular channels that heal with a brown, corky- 

 scab. Experience has shown that the best results are obtained from 

 the third or after-blossom spray, even the residue of a spray apphed 

 two weeks before the emergence of the larvae being of more value in 

 poisoning the larvae than one apphed at full strength two days after 

 their emergence. 



In orchards for the spray inunediately after the blossoms the follow- 

 ing are recommended : — (1) Standard lead arsenate paste 12 lb. to 

 15 lb. to 100 gals, water ; no fungicide is required, the arsenate at 

 this strength being itself efl&cient for this purpose. (2) Sodium 

 sulphide (soluble sulphur 3 to 3| lb., Sulphocide, 2 to 2| quarts, Spra 

 sulphur 31b.), calcium arsenate 1^ lb. (in serious outbreaks 1| to 

 2 lb.), hydrated or water-slaked hme 20 to 25 lb., water 100 gals. 

 (3) Lime-sulphur 1-006 sp. gr., or 2 gals, commercial concentrate 

 to 100 gals, water, and calcium arsenate 1| to 2 lb. to 100 gals. In 

 applying lime-sulphur for the third spray, the under-side of the leaves 

 should not be wetted.
