The Take-all Disease of Cereals and Grasses 



15 



McKinney (1921) called attention to reports of its appearance in Arkansas 

 and Oregon. The writers state also that a " similar " trouble, of which 

 investigations have indicated " a difference cause," has appeared in 

 Virginia. Later, in a numeration of the various collections of take-all 

 which have been made, McKinney (1923) alludes to the fact that the 

 material collected in Virginia was in reality take-all, perithecia having 

 apparently been^discovered subsequently by members of the staff of the

 In L922 take-all was reported from Indiana and from additional localities 

 in New York (Kirby, 1922), and it was shown that the disease was present 

 in Kansas. 2 In 1923 specimens of the fungus which were collected in 

 Tennessee in May were identified by the writer. 3 In addition the disease 

 was reporled from California (Mackie, 1923), and during July of 1923 

 Dr. J. A. Clark informed the writer that a considerable area of wheat 

 infested with take-all had been found in North Carolina.
