Hoist. W. A. Graham, 



"■} 



Commissioner of Agriculture. 



Sir: — I submit lierewith results of some work iu the control of 

 tobacco wilt on the Granville Branch Station farm. The results of 

 these investigations, Avhich were made by Mr. E. G. Moss, Assistant 

 Director of this station, and Dr. F. A. Wolf, Plant Pathologist of the 

 Experiment Station, show that wilt can be satisfactorily controlled by 

 a system of cropping or rotation in which tobacco is not grown on the 

 infested fields for a period of years. I recommend that this paper be 

 published as the December Bulletin. 



Very respectfully, 



B. W. Kjlgore, 



Director, Test Farms. 

 Approved for printing: 



W. A. Graham, 



Commissioner.
