GENERAL TREATMENT FOR CHERRIES. 



Cherry trees may be infested with San Jose scale. If found, the 

 treatment is the same as that recommended for the apple. 



Just Before the Blossoms Open, spray with dilute lime-sulphur, or 

 bordeaux mixture. This is to prevent the rot and leaf spot troubles. 

 Especially valuable on the English Morellos for the latter. Our ex- 

 periments the last two seasons indicate that the dilute lime-sulphur 

 is just as satisfactory as the bordeaux for cherries and either is better 

 than the self-boiled lime-sulphur. 



Just After the Blossoms Fall, make a spraying like the above with 

 the addition of 2 pounds of arsenate of lead to every 50 gallons of spray 

 solution. This spraying is directed against the rot and leaf spot, cur- 

 culio and slug. 



Ten Days or Two Weeks Later^ it may be necessary to make another 

 spraying like the previous one for the rot and leaf spot. The need for 

 this spraying will depend upon the susceptibility of the variety to the rot 

 and to the weather conditions of tJie season. 



Large Black Lice may appear on the leaves at any time. A spraying 

 of tobacco water (see page 120) will destroy them if applied before the 

 leaves curl too tightly. 



Slugs sometimes appear after the fruit is harvested, a spraying of 

 arsenate of lead (2 or 3 pounds in 50 gallons of water) will destroy them. 



GENERAL TREATMENT FOR GRAPES. 



Grape vines are not often subject to attacks by scale insects so there 

 is seldom need for a spraying with strong lime-sulphur before growth 

 starts. 



Do not use the dilute lime-sulphur at any time for grape spraying. 

 It stunts or checks the growth of the berries. Use the bordeaux mix- 

 ture. 



Downy Mildew commonly called "Red Grape" was very destructive 

 last season and caused large financial losses to growers who did not 

 spray. 



Black Rot has been a serious disease in recent seasons. Growers 

 cannot afford to risk the loss it may cause by neglecting to spray. 



These diseases and others will be prevented very largely by spraying 

 as follows: 



When the Shoots Are About 8 to 10 Inches Long, spray with bord- 

 eaux mixture for black rot and downy mildew.
