SPRAYING CALENDAR. 



Special Bulletin No. 19. -Horticultural Department. 



Whenever an asterisk (*) is used, it cautions against spraying trees with poisons while they are in 

 blossom. 



tFor the San Jose scale upon apple and other trees use the sulphur, lime and salt mixture. When 

 upoB small trees, kerosene may be applied with an_atomizer. 



Farmers and fruit growers are beginning to understand the impor- 

 tance of the use of insecticides and fungicides to preserve their crops 

 from the attacks of insects and diseases. To supply information as to 

 the best remedies and the methods of preparing and using them, in a 

 form that can be preserved so as to be convenient for reference, the fol- 

 lowing bulletin has been prepared. The remedies have been thoroughly 

 tested, and if the directions regarding their preparation and application 

 are carefully followed, they will be found effectual and can be used with- 

 out danger to the foliage and fruit, or the health of the consumer. 



Explanation : While the entire number of applications given will be 

 found desirable in seasons when insects and fungous diseases are par- 

 ticularly troublesome, and in the case of varieties that are subject to at- 

 tack, a smaller number will often suffice. To indicate those that are of 

 greatest importance, italics have been used, while others, that, although 

 seldom i-equired, may sometimes be of value, are printed in plain type.
