2. Several projects are now In progress under the Local 

 Experiment Fund, including a study of the roots of dasheen 

 both in the field and in storage, a new disease of the pecan, 

 Japanese persimmon, and cherry, plum and peach. 



Five fungi causing a rotting of dasheen in storage have been 

 studied in the laboratory. In an experiment now in progress, 

 an attempt was made to determine what fungi causing rots in 

 storage would develop in the field from the use of diseased 

 conns. To date, all results have been negative, showing that 

 these fungi, while they are very destructive in storage, do not 

 seriously affect the germination of the corm and are unable to 

 attack the growing plants. 



A Diplodia and Botyrospharia have been isolated from 

 diseased material of pecan and other hosts mentioned above. 

 Many field observations were made during the course of the 

 year. Some inoculation work has been attempted in the green- 

 house and field at Auburn. A study of these troubles will be 

 continued. 



Field and laboratory observations have also been made 

 on the anthracnose of cereals, Physoderma disease of corn, 

 peanut yellows, and several spot diseases of the legumes. 



3. List of projects: 



Adams Fund — Citrus Canker. 



Local Experiment Fund — Storage and Field Rots of the 

 Dasheen. Wilt and Die Back of Pecan, Japanese Persimmon, 

 Plum, Cherry and Peach. Miscellaneous Phytopathological in- 

 ves^tigations. 



4. The Department of Plant Pathology is cooperating to 

 some extent with Dr. W. T. Swingle, of the office of Crop Phy- 

 siology and Breeding Investigations, Bureau of Plant Industry, 

 Dr. K. F. Kellerman, Associate Chief of the Bureau of Plant In- 

 dustry, and Dr. E. C. Stakman, of the office of Cereal Investi- 

 gations and Minnesota Agricultural Experiment Station. All 

 three of these agreements are of recent date so that no results 

 have been obtained as yet. 



Respectfully submitted,
