II. SPKAY PUMPS AND SPRAYING.* 



WENDELL PADDOCK. 



SUMMARY. 



We are constantlj^ in receipt of inquiries concerning spraying 

 apparatus and methods of spraying, which show that elementary 

 instruction on this subject is still needed. The following pages 

 were prepared to meet this want, and the bulletin is addressed 

 to those persons who are seeking such information. 



Some of the spraying machinery now on the market that has 

 been tested at this station is illustrated and described and the 

 addresses of the firms manufacturing it are given. The formulas 

 of the prindpal mixtures used in spraying are given and many 

 necessities and conveniences are mentioned. v 



Important notice. — Do not spray trees or plants when in bloom. 

 It is in no instance necessary or desirable. By so doing not only 

 are we liable to injure the delicate parts of the flowers, but what 

 is more imi)ortant, to poison the bees and other insects that are 

 our friends. It would be impossible to grow some of our fruits 

 commercially without the aid of insects in fertilizing the blos- 

 soms. 



INTRODUCTION. 



Since spraying has become one of the operations of culture 

 with so many farmers and fruit growers, it would seem as if 

 explicit directions were now almost superfluous. Numerous bul- 

 letins on the subject have been issued by our experiment stations, 

 and the pages of agricultural and horticultural papers are alive 

 with discussions on the subject. However, that there are many 

 localities in the State where the methods of spraying are not 

 understood is revealed by the numerous letters of inquiry that 

 are received at this Station.
