THE CANADIAN HORTICULTURIST. 



Fortunately, we have now included 

 among our fruit testing stations the 

 Government pioneer farm at Dryden, 

 and have forwarded them a good col- 



lection of hardy trees of various fruits, 

 and we hope the results may be helpful 

 to our friends in Southern Manitoba. 



THE PEACH CURL. 



Fig. 1630.— Treated Leaf. 



THE nature of this fungus and its 

 life history, has been several times 

 fully described in these pages, but 

 it remains to instance another 

 clear case of successful treatment of it 

 by spraying. Mr. W. M. Orr, in 1898, 

 was the first in Canada to try white- 

 washing his peach trees in winter season 

 "with a view of preventing the curl. His 

 success was very marked, and was 

 given to the public in his annual report. 

 This spring, Mr. A. H. Pettit, of 

 Grimsby, sprayed his large peach 

 orchard, first in February, and then 

 again in March, using for first applica- 

 tion one peck of lime to 40 gallons 

 Bordeaux mixture, and the second 

 time, one half bushel. One row right 

 through the orchard was left unsprayed 



— embracing nearly every variety. As 

 the growth began the result became 

 more and more apparent, every other 

 row being free from curl leaf except the 

 one unsprayed, on which the foliage was 

 very considerably affected and the 

 ground beneath was strewed with dead 

 leaves, while under the others none 

 could be seen. Numerous visitors 

 studied effects of the treatment and 

 were convinced of its effectiveness, and 

 believe that, had the season being a wet 

 one, the difference between the treated 

 and the untreated trees would have been 

 still more marked. Our engravings are 

 taken from the leaves of the treated 

 (fig. 1630.) and untreated (fig 1631.) 

 trees.
