II. investigation. 



During the year, satisfactory progress has been made on all the 

 problems under investigation. On a number of these the work has 

 for the present been practically completed. 



(a) Hollyhock diseases. — The work on the diseases of holly- 

 hocks has been brought to a close and the main results of the 

 investigation will be ready for publication this winter. 



(b) Gladiolus diseases. — The work on the bulb rots of Gladio- 

 lus will also be completed and ready for publication this fall. This 

 investigation which has been done by Mr. Wallace, a graduate 

 student in the department, has been chiefly an examination into the 

 nature and causes of several serious rots of gladiolus bulbs occur- 

 ring on native and imported stock, of which up to the present 

 practically nothing has been known. Unfortunately it has not been 

 possible to do anything as yet on the control of these diseases. 

 As Mr. Wallace has now taken up another line of investigation, 

 further work on this problem must rest. It seems desirable, there- 

 fore, to publish what has thus far been discovered. This investi- 

 gation has been made possible by the cordial cooperation and finan- 

 cial support of Mr. Cowee of Berlin, N. Y., the largest grower of 

 Gladioli in this country. 



(c) Ginseng diseases. — With the cooperation and financial sup- 

 port of the ginseng growers of the State, we have been able this 

 season to complete the work on the Alternaria Blight, the most 

 common and destructive disease of cultivated ginseng in this State. 

 A bulletin on the subject is now in ])rcparation. With the ($200) 

 two hundred dollars placed at the disposal of the Department of 

 Plant Pathology by the ginseng growers of the State, we have been 

 able to employ Mr. W. H. Rankin as special assistant in the work. 

 A new and serious disease has been discovered, the Alildew, in 

 some of the gardens in the State. The nature of the malady, which 

 is well known in Japanese ginseng, has been carefully investigated 

 and means for controlling it carefully tested. It is expected that 

 a bulletin on this disease will be ready for publication by spring. 



A rot of the fibrous roots, particularly of seedlings and two- and 

 three-year-olds, has been very widespread and destructive in the 

 gardens of the State this season. This has proved to be caused by 

 a fungus, TJiielaina baslcola, well known as the cause of a serious 

 root rot of tobacco in Connecticut. A careful description of the
