The nursery business, alea, is very large in Westem New York. 

 It is especially prominent in the vicinity of Rochester^ Geneva 

 and Dansville. Several thousands of acres are devoted to the 

 growing of nursery stock, 



GEXBRAL STATEtMENT OF RESULTS. 



On account of the drought most fruit diseases were probably 

 much less destructive than usual. In many cases the expense of 

 spraying was wholly wasted because there was nothing to spray 

 for. Many localities were practically exempt from the common 

 fruit diseases which are ordinarily very destructive. In some 

 other localities, however, certain of these diseases caused much 

 damage. These variations were due to differences in local con- 

 ditions, chiefly rainfall. So far as its influence on fungous dis- 

 eases is concerned the total amount of rainfall is not nearly so 

 important as the manner of its distribution. Frequent, light 

 showers are more favorable to the growth of parasitic fungi than 

 heavy showers at long intervals. 



It will be observed that the accounts of several of the diseases 

 discussed in this bulletin are very incomplete. We met with 

 many puzzling things upon which we were unable to make suffi- 

 cient observations for want of time. The field was entirely too 

 large to be covered thoroughly in a single season. Still we think 

 it best to publish these observations even though they be frag- 

 mentary. They at least furnish suggestions for further study. 



APPLE DISEASES.^ 



The heavy gale of September 12 blew off large quantities of 

 apples. In many orchards from 25 to 50 per ct, of the fruit 

 fell. So far as the apple crop is concerned this wind was by far 

 the greatest disaster of the season. No disease has caused wide- 

 spread destruction; in fact, no disease has been at all conspicu- 

 ous except in a few localities. 



Scab (Fusicladium dendriticum (Wallr.) Fckl.). — This has done 

 very little damage. We have observed no orchard in which it 

 has caused sufficient injury to warrant the expense of spraying. 



*In this bulletin no account is taken of damage caused by insects.
