THE CANADIAN HORTICULTURIST. 



J. McP. ROSS. 



The vice-president 

 of the Fruit, Flower 

 and Honey Show, 

 Mr. J. McPherson 

 Ross, of Toronto, 

 has had a wide hor- 

 ticultural experi- 

 ence. For several 

 years Mr. Ross was 

 actively engaged in 

 the nursery busi- 

 ness. He is an en- 

 tertaining speaker 

 and has contributed 

 some interesting ar- 

 ticles to The Horti- 

 culturist. As a mem- 

 ber of the Toronto 

 Horticultural Socie- 

 ty Mr. Ross has held 

 numerous offices, in- 

 cluding that of pres- 

 ident. 



dust sprays, but, although fairly good re- 

 sults are secured against leaf eating insects 

 and the codling moth, it does not appear to 

 be nearly as effectual against apple scab as 

 the liquid Bordeaux mixture. When the 

 trees are growing under proper conditions 

 and receive from three to five applications 

 of Bordeaux mixture, according to the 

 variety and climatic conditions, the injury 

 from apple sc^b is reduced to a minimum. 



SETTLING DOWN TO SPRAYING. 



Prof. John Craig: INlew York fruit 

 growers are using no specially new methods 

 for controlling apple scab. They are real- 

 izing more keenly every year, however, that 

 thoroughness of method is more important 

 than small differences of formula or small 

 variations in time of application, and that it 

 is impra'^tlcable to make exact rules cover- 

 ing time of application and formula used. 

 The character of the season will or should 

 vary the treatment year by year. Our sea- 

 son this year may be considered to present 

 the normal type — perhaps a little more 

 rainv than usual. 



The best growers are settling down to the 

 habit of spraying thoroughly with Bordeaux 

 mixture and an arsenite just before the blos- 

 soms open, again after the blossoms fall, 

 and a third time when it appears desirable. 

 Sometimes they are satisfied with two spray- 

 ings. As a rule, however, three applica- 

 tions are made. Last year the best results 

 were secured by those w^ho sprayed rather 

 late in the season, and so it was the previous 

 season. It is safe to say, finally, that noth- 

 ing specially new in the methods of prevent- 

 ing apple scab have developed during the 

 past year or two, but that fruit growers are 

 becoming each year more impressed with 

 the necessity of doing the work thoroughly.

Prof. H. L. Hutt: It has long been es- 

 tabHshed, by repeated experiments, that 

 apple scab can be controlled by thorough 

 spraying with Bordeaux mixture. The 

 mixture should be applied before the buds 

 open in the spring, then again after the blos- 

 soms have fallen, and should be repeated 

 two or three times at intervals of ten days 

 or two weeks, depending somewhat on the 

 season. If rains are frequent the mixture 

 should be applied oftener. Usually four 

 or five sprayings are sufficient to keep the 

 disease in check. 



It is a good plan to allow hogs in the or- 

 chard to gather up all the fallen and dis- 

 eased apples, as these contain spores which 

 carry over the disease from one season to 

 another. Spraying should not be neglected 

 on trees when not carrying a crop, nor even 

 on young trees not yet in bearing, for the 

 disease lives on the foliage as well as the 

 fruit, and it is only by thorough and system- 

 atic spraying from year to year that it can 

 be reduced to a minimum. 



I have taken The Canadian Horticulturist for 

 years and could not get along without it very- 

 well. I find it very helpful and interesting. —
