454 Brooks : The Fruit Spot of apples 



spring on apples that have lain on the ground over the winter. 

 and thus become the agency in starting the disease the next season. 



8. Spraying with Bordeaux is a preventive for the disease. 

 Applications made late in June or early in July are as effective as 

 those made earlier in the season. 



9. By his references to the work reported from other stations 

 the writer would not be understood to imply that the disease here 

 under special consideration is identical with that described from 

 any other section. However, he does not find anything in some 

 of these reports to show that the Fruit Spot which is common in 

 New Hampshire may not sometimes have been included along 

 with the Fruit Pit in these descriptions. Further, this study leads 

 the writer to the conclusion that because particular pathological 

 conditions may originate without the presence of any foreign 

 agency, this should not be taken as proof that very similar results 

 may not be due to the presence of a parasitic fungus in the host 

 tissue.
