lieve if the orchards had been properly sprayed we could have 

 saved the trees inthe majority of cases. It seems that thorough 

 spraying is of prime imi^ortance and that the ai^plications should 

 come about as follows, with Bordeaux mixture: 



First spraying in spring, while the trees are yet dormant, 

 using the 4 to 4 mixture. This is to catch the spores that 

 might be lodged in the bud scales. 



The second spraying need not come until about ten days after 

 the petals of the flower have fallen. This application is delayed 

 because the leaves and flowers are opening at the same time 

 and it is difficult to spray without injuring the fruit crop. 



The third spraying should come immediately after the fruit 

 crop is harvested, and it is not safe to use over a 2 to 2 mixture 

 at this time. This is about the time that the first infected 

 leaves are falling and I take it that this is a dangerous time for 

 new infection. If a fourth spraying seems to be necessary, it 

 should come about twenty or twenty-five days later, 



I am satisfied that this treatment will save our trees, even if 

 it does not insure us a crop of cherries.
