Seventeenth Annual Report oe the 



that conditions so far as San Jose scale is concerned have changed 

 materially within the last few years. At one time it was deemed 

 necessary to destroy all infested trees but at the present time all 

 inspections are for the purpose of pointing out to the owners of 

 the orchards the presence of San Jose scale with suitable treatment 

 which can be carried on by the owners. Occasionally it is neces- 

 sary to serve notice upon the owners, requiring them to spray their 

 trees within a reasonable time limit, though the large commercial 

 orchardists are inclined to do what they can to save their orchards 

 and fruits. The lime and sulphur solution is found sufficient for 

 controlling the spread of the scales and is furthermore reported to 

 be useful as a fungicide. In the case of peaches, both San Jose 

 scale and leaf curl yield to proper treatment. Black knot of the 

 plum is prevalent in some areas and a large number of trees have 

 either been destroyed or thoroughly pruned and the owners 

 instructed as to future care. The following is a list of orchards 

 inspected, together with the number of trees the orchards con-

PEACH DISEASES 



The summer inspection for peach yellows and little peach has 

 been carried on in some portions of the peach belt, particularly in 

 the western New York belt referred to in the report of last year. 

 It will be remembered that a few years since we began a systematic 

 inspection of an area of about 60 square miles in Niagara County, 

 working on the theory that if every diseased peach tree were 

 annually cut out, the disease would be exterminated. The result 

 of the work this year shows that a smaller percentage of diseased
