594 ANNUAL REPORT OF THE Off. Doc. 



The best symptoms of this disease are the premature red spotted 

 fruits which occur on the diseased trees, even before they show the 

 yellow discoloration of the foliage. Later a wiry twig growth occurs 

 and a yellowing of the foliage. The yellowing foliage is typical but 

 hard to describe and is often confused with similar discoloration* 

 produced by borers, winter killing, starvation, root aphis and other 

 causes. It will be noted that the last two diseases are controllable 

 by the eradication method. 



It might be well to call your attention to the fact that this is an 

 entirely different style, of treatment from the spraying which has 

 yielded such excellent results in other lines of orchard diseases. 

 But we have parallel cases in diseases of animals and even in human 

 diseases. While there is no remedy for small-pox, typhoid fever nor 

 yellow fever, yet these diseases are controlled by quarantine and 

 isolation and destruction of the infection centres and the mosquito 

 and flies which carry the disease about, paralleling our destruction 

 of the infection centres in pear blight and peach yellows. In dis- 

 eases of animals the foot-and-mouth disease of New England and 

 the pleura-pneumonia have been controlled by killing and burying 

 or destroying the infected herds. Greater triumphs have been se- 

 cured in a way by these quarantine methods than by doping people 

 with medicines. So in our orchard pathology; in case of certain dis- 

 eases like pear blight, peach yellows and the rest of the yellows 

 group, we can achieve greater triumphs by stamping out and con- 

 trolling diseases than by the more expensive annual treatment by 

 spraying.
