32 Second Annual Report 



ripens about the middle of August at Ottawa. Seedlings from 

 this may be even more useful. 



Prunus Japonica — This is classed with the cherries although 

 this shrub, like Prunus tomentosa, does not resemble a cherry 

 very much. It is only about three feet in height, but bears a 

 good crop of fruit every year. The fruit is about the size of a 

 Fay's Prolific currant and deep dull red in colour. The quality 

 is rather poor, but this species may prove useful either as a 

 stock or in cross-breeding. 



Seedlings of the Koslov Morello, Compass Cherry, Downy- 

 kaved Cherry, and Prunus Japonica are being grown at Ottawa 

 in the hope of obtaining something better than the original,, 

 and as time permits,, work in cross-breeding will be carried 

 on also. Some of these may also be useful as dwarfing stocks 

 for the ordinary cherries as at present there is no satisfactory 

 hardy really dwarf stock used. The Mahaleb does not dwarf 

 sufficiently and is not hardy enough for the North. It appears 

 to us that there is a good field here for useful work. 



SUGGESTIONS ON THE PREPARATION AND USE OF 

 FUNGICIDES AND INSECTICIDES. 



BY WM. STUART. 



The replies received from a circular letter recently sent out 

 to the fruit growers of the State revealed the fact that {put com- 

 paratively few of them had paid any attention to spraying the 

 past season. Out of ninety-six replies only seven reported hav- 

 ing sprayed at all. Of this number, one sprayed four times, 

 one three, one twice, and four once. Twenty-five reported 

 having more or less scab on their fruit, nine reported damage 

 from codling moth and thirty-one from apple maggot. The 

 fact that twenty-five percent from whom replies were received 

 reported the presence of apple scab, suggested that this fungus 

 was again becoming abundant and widespread as indicated by 

 the dififerent counties of the State from which the reports were 

 received. Should climatic conditions favor the growth of the 

 scab fungus the coming season it will undoubtedly cause a large 

 amount of injury to unsprayed fruit trees. The absence of apple 

 scab in any appreciable amount the past two seasons, following 

 as it did the unprecedented season of 1902, in which sprayed 

 trees suffered almost as badly as unsprayed,, has done much to 

 make the fruit grower careless and even to cause some to regard 

 spraying as an unnecessary evil.
