437. Enemies. Barley probably suffers more from 

 the attacks of chinch bugs than any other cereal. This 

 may be due to the fact that the chinch-bugs are especially 

 fond of this crop. It is thought by some that barley is less 

 able to resist their attacks than the other cereals. The 

 Hessian fly also attacks barley. 



Barley is affected by black stem-rust and the orange 

 leaf-rust. There are also two common smuts of barley. 

 These are the covered smut and the loose smut (Fig. 60). 

 The treatment for the covered smut is the same as for 

 covered or stinking smut of wheat, page 339. The loose 

 smut of barley cannot be prevented by the use of formalin. 

 It can be controlled by the modified hot-water treatment, as 

 given for loose smut of wheat, page 338, with the exception 

 that barley is treated for 13 minutes at a temperature of 

 126 F. instead of 10 minutes at a temperature of 129 F. 

 as for wheat.
