CHAPTER XV 



ENEMIES OF THE POTATO 



THE potato is less subject to diseases and 

 pests in the higher mountain country 

 where it grows wild, than in any other part 

 of the world. 



Thousands of tons of tubers — the bulk of the 

 crop of the world, in fact — are produced where 

 the grower must fight many kinds of fungous and 

 insect enemies. 



The large amount of work being done along the 

 line of securing disease resistant varieties — either 

 by selection or hybridizing — has resulted in the 

 production of some varieties of market value for 

 the disease infested regions, and doubtless more 

 will be produced. 



The enemies of the potato may be divided into 

 two classes; diseases and insects. 



The diseases include: 

 Bhghts, 

 Scab, 



Rot of various kinds. 

 Black leg, 

 Black scab or European wart disease. 



Among the insect enemies are: 

 Flea beetles, 

 Colorado potato beetle, 

 Potato bug, .
