THE EEPOET OF THE 



No. 36 



The Meteorological Eecords of the six months (March till August) were as 

 follows : — 



Attacking Fruit Trees. 



San Jose Scale (Aspidiokis perniciosiis). While the area of infestation 

 does not appear to have decreased to any extent, it may be supposed that the con- 

 stant spraying, which process may now be considered the rule and not the exception, 

 among the great majority of fruit growers in the Niagara District, is affecting 

 its numbers. The district south and east of St. Catharines still remains the worst 

 infested. There are a great many old apple orchards in these districts, and they 

 harbour the San Jose to a very marked extent. 



Owing to the extensive and energetic operations of the National Land, Fruit 

 and Packing Company — a Company which in the last year has rented large numbers 

 of apple orchards throughout Ontario, and to a large degree around St. Catharines 

 and in the district south, and which has pruned, reheaded and sprayed these infested 

 orchards, many of which are under their control — we shall no doubt find, in a few 

 years, marked results against the Scale, and, for the good of the district as a whole. 

 We sincerely hope so. 



Excellent results, ending with the complete destruction of the Scale have been 

 evidenced this last year by two applications of Commercial Lime Sulphur at thr 

 1-10 strength, before the buds fully burst in the Spring and when the ground was 

 still frozen. Single applications of 1-10 in the early Spring have not given the best 

 results, probably owing entirely to the degree of efficiency in application. A single 

 application of 1-8 or stronger has been recommended, and is now being recom- 

 mended as efficient, by local Inspectors. But it would appear that the fault 

 does not lie in the strength of the application so much as in the degree of efficiency 

 of application, consequently on a badly infested tree and especially on a large 

 number of trees, I would prefer two applications of 1-10 or even weaker to a 

 single application of 1-8 or stronger. 



Codling Moth {Carpocapsa pomonella). It has been predicted that owing 

 to the failure of the apple crop of 1910, we would notice a marked decrease in the 

 percentage of "wormy" apples this year — because it was supposed a lessening in 

 food supply would in turn affect the numbers of the moth. I have not seen any 

 direct evidence of this coming about, but it is true I have not sufficient data at 

 hand. I had occasion to be away from the Niagara District at the time when the 

 second brood was in operation, consequently I have no facts to guide me. If th^ 



• The maximum thermometer was broken, and no maximum records were kept from 

 March 20th till May 18th. Consequently the average for March is too low, while the 

 average for May is too high.
