For the dormant season's spraying a nozzle of the Bordeaux type will do 

 the most thorough work, especially on the older trees. The angled nozzle 

 suits the writer best for all purix>ses. 



Permit me again to draw your attention to the necessity of thorough and 

 systematic work by spraying at the right time and with the right mixture. 

 Much of the unsatisfactory results obtained in combating fungus pests has 

 been due to insufficient knowledge of the pest under control. By reading 

 this bulletin carefully, the fruit-grower should be able to obtain at least 

 a " fighting " knowledge of the pest. It is to be hoped that fall spraying 

 in the future will be carried on generally, regularly, and systematically, 

 especially in the Coast districts.
