alarming, lie must catch the insects by jarring them onto sheets. 

 There are those who declare that they attract the curculio away 

 from the cherries by planting plum trees in the cherry orchard, 

 but I greatly doubt the elficiency of this procedure. A complete 

 account of the curculio may be expected in a forthcoming bulletin. 



The leaf-blight or shot-hole fungus {Cylindrosporium Padi, or 

 Septoria cerasina, the same which attacks the plum), is often a 

 serious enemy, particularly upon the English Morello. The leaves 

 begin to assume a spotted character, generally before the fruit is 

 picked, they soon turn yellow, and they fall prematurely. 

 Thorough spraying with Bordeaux mixture is as efficient in holding 

 the leaves on the cherry as it is on the plum. The trees should 

 generally be sprayed twice between the falling of the blossoms and 

 the coloring of the fruit. If the cherries are more than half grown 

 when the last spraj^ is applied, the ammonical carbonate of copper 

 may be used in place of the Bordeaux, to avoid discoloring the fruit. 

 But it is doubtful if the last spray should be delayed until this time. 

 It may be necessary to spray once after the fruit is ofE, 



A thin grayish powderly mildew {PodosjyJimra Oxyacanihce) fre- 

 quently attacks the fruits and leaves of the sour cherries, particu- 

 larly when the trees are overshadowed by larger trees or buildings. 

 I have never known it to be serious upon the fruit, as it appears 

 about the time the fruit is ripening, covering the cherries with a 

 very delicate coat, like dust. In this case a late spraying with 

 ammonical carbonate of copper would certainly be effective. The 

 only emphatic injury which I have ever seen from this fungus 

 upon cherries occurs aftei- the fruit is off, when it may attack the 

 ends of the shoots, checking the growth. At this time, if the 

 injury threatens to be serious, Bordeaux mixture may be used. 



The black-knot, which seriously invades sour cherry trees, is fully 

 treated in our Bulletin 81. 



III. THE SWEET CHERRY INDUSTRY. 



Unlike most other fruits, the sweet cherry has never attained a 

 prominent position as a horticultural industry in western New York. 

 There is not a single orchard of it west of Albany, so far as I know. 

 Along the Hudson, however, there are three or four orchards. It 

 is from the few trees scattered on eveiy farm throughout the State, 

 that the cherry crop is mostly harvested. It should not be concluded.
