PART III 

 SPECIAL PLANT PATHOLOGY 



CHAPTER XXXIII 



LIST OF SPECIFIC DISEASES OF PLANTS 



The remarkable growth of the work of the United States Depart- 

 ment of Agriculture, and that of the agricultural experiment stations of 

 the different states, has been along the most diverse lines. Mycology 

 has been given prominence and the number of trained workers in this 

 field has increased to such an extent, that a separate organization, 

 known as the American Phytopathological Society, has been found 

 necessary. The meetings of this society have been largely attended 

 and the papers read have been of the greatest value and interest. The 

 organ of the society, "Phytopathology," has published already a con- 

 siderable number of important papers, and it has set a high standard for 

 the future work along mycologic and pathologic lines. One of the 

 specific problems, which it has attempted to do through special com- 

 mittes appointed for the purposes, has been to suggest the use of com- 

 mon names of fungous diseases based on recognized rules of procedure 

 and to prepare a list of the common and important diseases of economic 

 plants in the United States and Canada. The preliminary report of 

 the committee on common names has been made, but considerable 

 time must elapse before the list of common and important diseases is 

 completed. 



As this book will be printed and issued before the preliminary list of 

 the American Phytopathological Society of fungous diseases appears, 

 it has been deemed advisable to compile a list from various sources of 

 information for the common host plants in the United States and 

 Canada, using the "Literature of Plant Diseases" given by W. C. 

 Sturgis in the Report of the Connecticut Agricultural Experiment 

 Station for the year ending Oct. 31, 1900, part III, pages 255-293, as 

 the basis of such a list.
