THE APPLE 



spraying is intended to destroy scale, insects, and the winter spores 

 of fungus and lichens. Trunks of trees should be sprayed as well 



as branches. 



The time for the 

 second spraying is 

 when buds show pink. 

 For this, full-strength 

 Bordeaux mixture with 

 2 pounds of arsenate 

 of lead added to each 

 50 gallons of the spray 

 material should be 

 used. This spraying 

 will destroy apple scale, 

 fungus, bud moth, can- 

 kerworms, and case- 

 bearers.

calyxes have closed, the 

 commercial lime-sulphur 

 solution, properly diluted 

 to summer strength with 

 2.\ pounds of arsenate of 

 lead added to every 50 

 gallons of the spray, is 

 recommended. This early 

 summer spraying is very 

 important, because if the 

 codling moth is to be de- 

 stroyed, the poison must 

 be forced into the calyx 

 cups before they close. 

 This spraying will also 

 destroy scab, blight, etc.
