SUMMARY. 



1. The apple-scab fungus, Fusicladium dendriticum, attacks apple- 

 trees very early in the season, even before the petals fall to the ground. 

 (Pages 266, 269.) 



2. The tirst application of a fungicide should be made early, no 

 later than immediately after the petals fall ; an application made just 

 before the buds open would probably be of value. (Page 269.) 



3. The time for combating the apple-worm is immediately after 

 the petals fall, and the treatment should be repeated once or twice 

 until the apples begin to hang down. (Page 267.) 



4. Apple-trees should be pruned so that all parts may easily be 

 reached by a spray; well-pruned trees allow free access of light and 

 air among their branches, which prevents fungi from obtaining so 

 strong a foothold. (Page 267.) 



5. The injury done by the apple-scab fungus was decidedly re- 

 duced where the Bordeaux mixture was used. (Page 272.) 



6. When Paris green was added to the Bordeaux mixture, the 

 fungicidal action of the combination was more marked than when Lon- 

 don purple was used in place of Paris green. (Page 272.) 



7. Paris green has a certain fungicidal value, but in this respect 

 it does not nearly equal the Bordeaux mixture. (Page 272.) 



8. The value of Paris green as an insecticide does not appear to 

 be materially affected, whether it is applied alone or in combination 

 with the Bordeaux mixture. (Pages 273, 274.)
