The destruction of our fruits to so large au extent for the past few 

 years by fungous pests and insects, shows us the necessity of using 

 every remedy that we know of for the destruction of the causes of 

 this loss. 



The many letters received at this Station asking for specific instruc- 

 tions relating to the use of the best known fungicides and insecticides 

 have led to the issue of this bulletin. 



Our information is based upon the experiments made at this Sta- 

 tion, those of the Department of Agriculture at Washington, the 

 work of many other Stations of the country, and the practice of the 

 large orchardists and vineyardists of the country, who have made 

 successful use of the remedies. 



The time which experiments have been carried on in this line, has 

 not been sufficient to decide in every case and under all conditions, 

 what may be the most economical and the safest remedy or mode of 

 application, but enough has been learned to warrant the recommen- 

 dation of the use of a few of the best known remedies, and we feel 

 confident that if the directions are carefully followed and no 

 unusual conditions present themselves, great benefit may be derived 

 from their use.

 destroy, the characteristics of which have been given in previous
