FOREWORD. 



Special Bulletin No. 54. 



All fruit trees, bushes and vines are attacked by many insects and 

 diseases that may destroy the crop entirely or very seriously lessen its 

 value. Fruit tuyeis and dealers do not care to huy or handle fruit 

 from orchards that have not hecn ivell sprayed. 



Proper, thorough and systematic spraying will protect the tree or bush 

 and may cause the difference between success and failure in the produc- 

 tion of a profitable crop. 



This outline aims to give methods of control for the more common 

 insects and diseases only. For pests not included, T\Tite to the Depart- 

 ment of p]utomology or the Department of Horticulture, Michigan Agri- 

 cultural College, East Lansing, Mich., as the case may be. Or consult 

 special bulletin 24, '^Insects Injurious to Fruits in Michigan," and 

 regular bulletin 233, ''Insects of the Garden."
