summer. The work thus far has been confined to testing different methods of pro- 

 pagating from cuttings, using green wood tips under glass and in the open air ; also 

 spring and fall planting in the open of hardwood cuttings. 



Interesting results are being developed, but the work is not sufficiently advanced 

 to report upon at this date. 



v.— EXPEEIMENTS WITH FUNGICIDES. 



The annual losses to orchards during the past eight or ten years from the disease 

 known as apple-scab (Fusicladium dentriticum pckl.) has been so heavy as to 

 cause some hitherto profitable varieties to be discarded in certain localities, and to 

 raise the question of their usefulness in future planting. These failures among old 

 and well-tried varieties have also brought about enquiry and experiment as to the 

 best means of combating the disease. 



A series of experiments along this line were conducted at Abbotsford, Que., dur- 

 ing the past season, on the farm of Wm. Craig & Son. I am indebted to Mr. Wm. 

 Craig, jr., for his labour in superintending the work, and furnishing me with some 

 of the facts upon which the following deductions are based. 



I am also indebted to Mr. F. T. Shutt, Chemist to the Experimental Farms, for 

 valuable assistance in planning the lines of experiments, and for the preparation of 

 the copper carbonate and other necessary materials. 



The trees selected were of the Fameuse variety, planted fourteen years ago on 

 a loose, gravelly soil. During the past four years this orchard has not yielded more 

 than 25 per cent, of first-class apples. 



Five rows in the centre of this orchard were selected, each row, which contained 

 fourteen trees, being treated with a different mixture. A row of trees untieated was 

 allowed to remain on either side of those operated upon. Four applications were 

 made, one on each of the following dates : 14th and 26ih June, and 17th and 29th 

 July. At the time of the first application the fruit was about the size of garden peas. 



When the fruit was picked it was divided into three grades, numbered 1, 2, 

 and 3. The results are given in this way : — 



Row 1. — Treated with 



Copper carbonate 1^ oz. 



Ammonia 1 qt. 



Water 22 gals. 



Result : Per cent. 



No. 1 33 



No. 2 25 



No. 3 42 



Row 2. — Treated with 



Copper carbonate 3 oz. 



Water 22 gals. 



Result: Percent. 



No. 1 50 



No. 2... 25 



No. 3 25 



Row 3. — Treated with 



Copper sulphate 1 lb. 



Ammonia 1^ pts. 



Water 22 gals.
