REPORT OF STATK HORTICULTURIST. 53 



As the Mcintosh at the present time is our most fancy apple 

 and as it is being planted as much as, if not more than, any other 

 variety, it is especially important that we keep this disease un- 

 der control ; inasmuch as the Mcintosh is the variety that suffers 

 more than any other because of it. 



Apples in sod have appeared to be less resistant to this dis- 

 ease than those under cultivation, showing that it isn't entirely 

 a question of spraying. Cultivation aids at all times. 



SPRAY MATERIALS. 



Inasmuch as Bordeaux mixture has, in many cases, proven 

 very unsatisfactory in orchard spraying, we have recommended 

 the use of lime-sulphur instead. Thus far very little complaint 

 has been made of burning the foliage and there has been no 

 russeting as far as I know. As both a dormant and a summer 

 spray it is proving to be the best. Growers that have tried 

 home boiling have had varying success but a majority have been 

 well satisfied with the results. The mixture has not been as 

 concentrated as the commercial but the effect upon scale and 

 fungus has been as satisfactory and the expense much less. 



Arsenate of lead has been recommended as an insecticide, as 

 it is eft'ective and clings to the foliage longer than any of the 

 other materials. Paris green and arsenate of lime are both apt 

 to burn the foliage and their use has been discouraged for that 

 reason. 



Arsenate of zinc is being heralded as a high quality spray 

 material and has proven satisfactory in many cases where it 

 has been given a trial. Its use will depend upon future results 

 and it might be well for growers to try a little in their spring 

 work. It is much cheaper than the lead and if as effective, will 

 largely take its place in spray work. 



Many inquiries liave constantly come in regarding fungicide 

 and insecticide manufacturers and spray pum.p manufacturers. 

 The following is a partial list recommended :
