164 BOARD OF AGRICULTURE. [Pub. Doc. 



have fallen, the spraying will be repeated, using both sub- 

 stances. In the seven to twenty days following, the same 

 application will again be made at two different times. This 

 applies more particularly to the apple and the pear, and 

 modifications will suggest themselves for other fruits. For 

 grape vines no Paris green will be needed. The last- 

 mentioned spraying will complete the round, unless the sea- 

 son shall prove to be one of unusual fungoid development, 

 in which case the copper spraying will be repeated whenever 

 it will be likely to be of service in arresting the progress of 

 any one or more fungi. 



If I am asked whether all these several operations are 

 equally essential, I answer No. I consider that the burn- 

 ing and the first spraying, previous to the appearance of the 

 foliage, arc more important than all the others combined, so 

 far as they relate to fungi. If we could exterminate every 

 winter spore, we should have no development of the sum- 

 mer growth. It is very much easier to prevent these mala- 

 dies than it is to cure them. They all arise from spores or 

 seeds, as much as do plants of purslane or corn. " Whatso- 

 ever a man sowcth," or permits to be sowed, " that shall he 

 also reap." In the matter of insects I think the spraying at 

 the close of the bloom to be the more important; but all 

 that I have mentioned arc desirable, and will liberally pay 

 their cost. Under this treatment I shall expect to find that 

 the losses by either fungi or insects will be reduced to the 

 minimum; and by an annual repetition, in the absence of 

 ignorant or negligent neighbors immediately west of me, I 

 shall hope to remain comparatively exempt in the future. 



The application of insecticides and fungicides in a water 

 spray has developed many contrivances for the purpose. As 

 might be expected, some of them arc more ingenious, elabo- 

 rate or expensive than useful. Inventors arc not often fruit 

 growers, nor arc the latter inventors. The different condi- 

 tions required are comparatively simple by themselves, but 

 in combination arc difficult or impossible of attainment. 

 What might be described as the perfection of the process 

 would be the finest possible division of the water, to be 

 deposited like dew upon every part of the foliage. This is 

 brought about by the druggist's atomizer, which, however,
