This disease may be treated in essen-

 liitter-rot fungus often continues its 

 destructive work after the fruit is har- 

 vested, care should be taken in stor- 

 ing to remove all fruit showing ev - 

 dence of the disease.

 soms fall 



Use No. 

 mant. 



4 or No. 5 when trees are dor- 



Cut all dead and diseased tissue, clean 

 and wash with bordeaux mixture. 



Dig a trench around the tree, cuttiug off 

 all roots, as the disease is communi- 

 cated from tree to tree through the 

 i-oots; destroy all affected trees. 



"When aphis appear use spray No. 6. 



When fruit has set, if slug appears, dust 

 leaves with air-slaked lime. 



Cut out gum pockets, split outer bark 

 from roots to branches when sap be- 

 gins to flow; wash with bordeaux mix- 

 ture. 



Use same sprays as for apple. 

 Use spray No. 8. 



Spray with No. 7 before buds open- 



Use No. 8 as buds begin swelling. 



Use either No. 12 or No. 13 just before 

 blossoms open.

 two weeks, up to 

 within three weeks

 aphis appear on fo- 

 liage.

Note.— Bordeaux mixture is a sovereign preventive for all fungous growths, using 

 the modified form when trees are in foliage. 



Note.— Lime should always be fresh slaked and the combined fungicide and insecti- 

 cide sprays should be used soon after making.
