PLATE io 
A. —Section through the ear node of a normal appearing stalk of Reid Yellow 
Dent. Note that the nodal tissues show no disintegration. 
B. —Section through an ear node of a stalk of Reid Yellow Dent, showing the 
disintegration of the nodal tissues due to the effects of aluminum and iron compounds. 
Fungi, especially Gibberella saubinetii, are very frequently isolated from these tissues, 
but not constantly. Diplodia zeae also has been found in stalks in certain fields. 
This nodal condition, however, has not been found to be associated with any specific 
organism.
