FUMIGATION OF APPLES FOR SAN JOSE SCALE. 



with the scale to insure its destruction as completely as possible by 

 spraying, not only to preserve the life of the trees, but to prevent the 

 marking of the fruit. 



In cases of light infestation the intrinsic value of the fruit is but 

 little affected, although the reddish spots or circles disfigure it for 

 market purposes, and its keeping qualities are perhaps reduced. 

 Despite care in packing and grading in infested orchards, a certain 

 amount of scaly fruit will usually find its way into the barrels or boxes, 

 and thus be distributed. In this connection is presented a table 

 (Table I), compiled from the reports a of Dr. C. Brick, chief inspector 

 in the Station fur Pflanzenschutz, at Hamburg, on the condition of 

 American apples received at that port during the years from 1888-9 

 to 1906-7, inclusive, considered merely as to infestation by the San 

 Jose scale, although report is made upon numerous other species of 

 scale insects and certain fungous diseases found present.
