" Fruit growers, as a rule, understand that fungi- 

 cides should be used as preventives, as when the 

 spores have germinated and have penetrated the 

 tissues the fungus has passed beyond the reach of 

 a surface application. While some benefit may 

 derive from spraying after the fungus is at work," 

 writes Prof. L. R. Taft of the Michigan experiment 

 station, " it is largely, if not entirely, in the way of 

 preventing the spread of the disease to other parts 

 of the plant or fruit. 



" In a general way, then, it can be said that the 

 only way to obtain perfect results from spraying 

 is to make the first application before the attack, 

 and renew it sufficiently often to keep all parts of 

 the trees covered with the fungicide during the 

 period of activity. 



*' So far as the insecticides are concerned, early 

 sprayings are also necessary, as nearly all of the 

 more troublesome insects injure plants by eating 

 the foliage or other exposed parts. Although they 

 can generally be held in check after the effect of 

 their work has been noticed, it is better to apply 

 the remedy just before the larvae are likely to 

 appear. 



" As a rule, it is advisable to spray, not only 

 apples, but all other fruits just before the blossoms
