Orchard Spraying. 



Spraying is now generally practised by our best apple 'growers and 

 the most successful growers are the firmest believers in the value of, and 

 necessity for, thorough, intelligent spraying. 



Thorough, intelligent spraying means (1) the use of a good spray- 

 pump and outfit, (2) a knowledge of the enemies to be treated, (3) 

 a knowledge of the remedies which have been found most effective, and 

 their preparation, and (4) the proper time for the application of the reme- 

 dies. It should be remembered that prevention of fungous diseases is 

 possible, but their cure is hardly practicable. 



The following spray Calendar for an apple orchard will be found very 

 helpful to the grower who makes an honest effort to spray successfully.
