92 Botany in the Extension Work. 



by which the ravages of this disease throughout the State might 

 be reduced. Tlianks to the kindness of two larg-e canning com- 

 panies at Rome and Oneida, N. Y., excellent opportunities were 

 afforded for testing the spraying of beans on large areas and with 

 the most modern apparatus. Moreover, these companies stood all 

 expenses in the way of materials and paid our traveling expenses. 

 The result of the summer's work seems to indicate that spraying for 

 this disease is not efficient at least so far as large field operations 

 are concerned. It is thought that we must look to other means for 

 the control of this disease. Repeated tests of seed in the laboratory 

 have shown that practically all of the seed offered in the markets is 

 badly diseased. During the next year it is planned to carry on 

 extensive tests of bean seed offered in the market and it is hoped 

 we may be able to devise a plan for the growing of clean beans for 

 seed. I believe that the solution of the problem lies in the obtaining 

 of seed entirely free from tlie disease. 



Second, the work on the Alternaria Blight of Ginseng was con- 

 tinued throughout the past season and the solution of the control 

 of this disease finally worked out. We were able to establish beyond 

 a doubt that thorough and systematic spraying would grow plants 

 perfectly free from the disease. 



Third, work on the fire blight of pears and apples was also carried 

 on to some extent in continuation of the work begun last year. It is 

 hoped that this work may be continued again next year. 



Fourth, spraying experiments on the Septoria Leaf Blight of 

 tomato were repeated again the past year with results that seemed 

 to indicate that this disease may be entirely controlled if the spray- 

 ing is properly done and the removal of the diseased leaves as iast 

 as they appear is systematically attended to. 



Fifth, some preliminary spraying experiments were also m.ade for 

 the control of the rust of hollyhocks. Two sprayings with Bor- 

 deaux mixture gave remarkable results in the control of this disease. 

 It is planned to complete the work on this problem next year. 



Sixth, some investigations were also made on the nature of the 

 root rot of peas. This disease caused considerable loss in the pea 

 fields of the State. The work was of a preliminary nature, and it 

 is expected that it may be carried on during the coming season. 



Three bulletins are now in preparation and it is hoped that at least 

 one of these may be ready for publication during the early part of 

 the coming year. These bulletins will be The Alternaria Blight of 

 Ginseng, The Fire Blight of Apples and Pears, and The Septoria 

 Leaf Blight of Tomatoes.
