[Special Bulletin No. 36.] 



Farmers and fruit growers are beginning to understand the import- 

 ance 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 applica- 

 tion are carefully followed, they will be found effectual and can be 

 used without danger to the foliage and fruit, or the health of the con- 

 sumer. 



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 

 attack, ^. smaller number will often suffice. To indicate those that are 

 of greatest importance, italics have been used, while others, that, al- 

 though seldom required, may sometimes be of value, are printed in plain 

 type. Whenever an asterisk (*) is used, it cautions against spraying 

 trees with poisons while they are in blossom.
