NINETEENTH ANNUAL MEETING. 161 



produced. It therefore behooves us to give this subject 

 the most careful consideration. The successful orchard- 

 ist of the future will be the man who among other things 

 studies the conditions existing on his own farm and sprays 

 his trees according to the needs of each variety for the 

 control of the particular troubles which occur in his local- 

 ity. The course of treatment best suited for the orchards 

 of one locality may not necessarily give the best results in 

 orchards situated in another locality, and again the treat- 

 ment for certain varieties of apples may be different from 

 that required for certain other varieties growing in the 

 same locality. The course of treatment should be planned 

 not only with reference to the diseases to be controlled, but 

 also with the reference to the probable effect of the fungicide 

 upon the fruit and foliage of the variety to be treated. 



These are some of the finer points to be considered in 

 connection with spraying, and the orchardist who gives 

 them due consideration will obtain the best results in the 

 production of good fruit. 



In recent years Bordeaux mixture has come into ill 

 favor among the apple growers on account of its injurious 

 effect upon the fruit and foliage, and there is a growing 

 demand for a fungicide which can be used for the control 

 of apple diseases without producing such injury. During 

 the past three years the writer has been working on this 

 problem and not without some success. The self-boiled lime- 

 sulphur wash which was developed primarily for spraying 

 peach trees has been found to be an excellent spray for the 

 control of mild cases of apple diseases and to be entirely 

 harmless to fruit and foliage. The concentrated lime-sul- 

 phur solutions* both commercial and home prepared, when 

 diluted to contain four pounds of sulphur to 50 gallons of 

 water have proved to be about as effective in the control 

 of apple scab and leaf-spot as Bordeaux mixture and to 

 be much less injurious.
