FIFTEENTH ANNUAL MEETING. 59 



but they may be far more convenient for s])raying' a few trees 

 in tlie g-arden. and seem to be especiall}- adapted for spraying 

 in ornamental plantings, where the lime-sulphnr washes are 

 objectionable because they show white on the trees and shrubs. 

 We should not lose siglit of the fact that the lime-sulphur wash 

 possesses fungicidal properties not found in any oil mixtures. 



Orchardists will doubtless practice fall spraying more and 

 more in the years to come. It is true that an occasional bud 

 is killed, but there are usually plenty left, and there is a possi- 

 bility of destroying a much larger proportion of the scales if 

 applied while the young are crawling. The breeding season 

 of the San Jose scale ends about December ist in Connecticut. 

 The leaves are usually off by November ist, so that the whole 

 month of November is available for spraying dormant trees, 

 and this is probably the most favorable time in the whole year 

 for doing the work. 



Your committee believes that there is no better remedy for 

 the pear psylla {Psylla pyricola Forst) than to spray the dor- 

 mant trees with a lime-sulphur wash, as for the destruction of 

 the San Jose scale. During the season following such treat- 

 ment pear trees have been found to be comparatively free from 

 psylla wherever I have examined them. 



Considerable injury was done to young peaches by the rose 

 beetle or chafer {Macrodactylus subspinosns Fabr.) in June. 

 This beetle was very abundant, and eats holes into the young 

 fruits, rendering them imperfect and causing them to shrivel 

 and sometimes to drop. As summer spraying generally 

 results in a serious injury to peach foliage in Connecticut, 

 there is no ]:)racticable remedy. 



The coddling-moth (Carpocapsa ponioncUa Linn.) was 

 fairly abundant, but this is not much to be feared by the 

 orchardist who sprays with arsenical poisons. Where spraying- 

 is not practiced, the insect is more conspicuous, and injures a 

 larger proportion of the fruit in a season where there is a 

 light croj) of fruit than in the case of a heavy crop. Hence 

 there was greater need of spraying in a season like 1905, than 

 in 19(34. 



The apple maggot {RhagoJetis pomonclla Walsh) is not 

 disappearing, but seems to be increasing in Connecticut
