12 



to bring the whole quantity up to 6 quarts. This eaii be kept in 

 an ordinary two gallon stone jar which should be closely corked. 



FORMULA. 



Each quart will contain 2 ounces of the carbonate of copper, which 

 when added to 25 gallons of water, will furnish a solution for 

 spraying, of the same strength and character as that obtained, by 

 the use of the dried carbonate, and one which can be prepared with 

 little labor, and kept ready for use throughout the season. 



CARBONATE OP COPPER IN SUSPENSION. 



When the carbonate is to be used in suspension, instead of adding 

 the ammonia to the sediment, add water until the whole quantity 

 is made up to 6 quarts. Stir this thoroughly until the sediment is 

 •completely suspended (entirely mixed throughout) and pour the 

 thick liquid into a suitable jar, when it will be ready for use. 



Before using shake the contents thoroughly, so that all the sediment 

 may be evenly distributed in the water. Pour out a quart of the 

 thick fluid and mix with 25 gallons of water. 



The cost of the chemicals will vary with the amount purchased 

 ■Copper Sulphate (blue vitriol) is usually retailed at from 10 to 12 cts. 

 per pound, and Sal Soda (washing soda) at about 3 cts. per pound. 

 The strong ammonia should be used which can be bought in half 

 gallon jars at from 20 to 25 cents per pint. 



WHEN TO SPRAY. 



The importance of early treatment cannot be too strongly urged, 

 as after the disease has gained foothold and is working within the 

 tissues, remedies which can only be applied externally are of very 

 little use. The first application should be made hejore the blossoms 

 ■open; the second soon after they have fallen, the third and fourth 

 following in periods of about ten days or two weeks apart. If the 

 season is cool and wet, a fifth application will be necessary, but if 

 moderately dry, four applications, if begun in good time, will in 

 all probability be sufficiently effective. 



HOW TO APPLY THE FUNGICIDE. 



1. For orchard work use some form of a barrel pump. 



2. Use nozzles which will distribute the liquid in a fine misty 

 spray.
