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

 l)eriments the last tw'o seasons indicate that the dilute lime-sulphur 

 is just as satisfactory as the liordcaux for cherries and either is bolter 

 than the self-boiled lime-sulphur. 



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

 the addition of 2 pounds of arecnate 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 an- 

 other 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 the season. 



Large Black Lice may api>ear on the leaves at any time. A spray- 

 ing of tobacco Avater (see page 363) will destroy them if applied l)efore 

 the leaves curl too tightly. 



SPRAYING EXGLISH MORELLO CHERRIES. 



On left: Sprayed three times with commercial lime-sulphur (properly diluted^. Fruit was protected 

 and foliage remained practically perfect through the season. Photo. Oct. 4, 1912. There was no 

 perceptible difference when the Bordeaux mixture was used. On right: Tree not sprayed. The fruit 

 was of no value and the foliage was entirely lost by mid-summer. The photograph was taken Oct. 4, 



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.
