The Office of Plant-Disease Survey and Pathological Collections 

 has been collecting specimens and data regarding the occurrence and 

 distribution of plant diseases in the United States for a number of 

 years, but no attempt has heretofore been made to prepare a list of 

 all the known diseases of economic importance in this country with 

 their distribution. It is believed that such a list will be of great 

 value to pathologists and others interested in plant diseases and 

 their control, as it will provide a means of determining quickly and 

 easily what diseases have been reported on our important economic 

 plants and their present known distribution, with the name of the 

 causal organism in the case of parasitic diseases and the common 

 name of the disease. It is hoped also that the list will be helpful 

 in bringing about greater uniformity and certainty in the use of both 

 common and scientific names. 



The list has been compiled from the office records, and much in- 

 formation and assistance nave been given by members of the various 

 pathological offices of the Bureau of Plant Industry and by some of 

 the Plant-Disease Survey collaborators, to all of whom thanks are 

 tendered.
