DISEASES. 153 



Often a white fungus occurs and permeates the 

 entire ear. 



This disease was first investigated in 1882, 

 and most of the information known of its char- 

 acter is derived from studies made of it by 

 Prof. T. J. Burrill of the Illinois experiment 

 station.* The malady is widely prevalent, with- 

 out doubt, yet is mainly known in Illinois and 

 Nebraska. It is thought that animals eating 

 cornstalks affected by this bacteria will die of 

 what is called "cornstalk disease." 



While this trouble is not confined to special 

 kinds of soils and conditions it has been found 

 most prevalent on rich land. 



Thus far the writer knows of no method 

 proposed to prevent the occurrence of this 

 disease. 



Rust occurs on Indian corn, but only to_a 

 slight extent and at uncertain periods. The 

 loss from this disease is probably very imma- 

 terial.
