Fruit rot checked. — So far as the fruit rot is concerned rather 

 encouraging results were obtained, although comparatively few 

 of the trees fruited, and even on unsprayed trees the rot was not 

 generally abundant. A careful estimate made when the fruit 

 was picked showed some advantage from the treatment. Especi- 

 ally in one group of trees the amount of rotted fruit was slight 

 while on unsj^rayed trees of the same variety which stood near, 

 from one-twentieth to one-fifth of the fruit rotted. In preventing 

 the rot, the eau celeste seemed to be as effective as the Bordeaux 

 mixture, but generally it injured the foliage much more than 

 Bordeaux mixture did. 



Foliage injured hy spraying^ — The results of the treatment for 

 the leaf -spot in 1895 were not very encouraging, because so much 

 of the foliage was injured by the spray. The last spraying was 

 made June 15, and from that time till the close of the season the 

 unsprayed trees were, generally speaking, in better condition 

 than were the trees which had been sprayed. 



As a rule the leaves were hurt much less by the Bordeaux mix- 

 ture than by the eau celeste. We were much surprised to find 

 an exception to this in the Reine Hortense of series I, where the 

 leaves were hurt much more by the Bordeaux mixture than they 

 were by the eau celeste. 



Experiments of 1896. 



Because the experiments in 1895 did not give conclusive evi- 

 dence on the points under investigation, the ^ork was continued 

 the following year. Mr. C. K. Scoon, of Geneva, N. Y., kindly 

 offered his orchard for the use of the Station for this work. 

 In view of the iiljury to the foliage which followed the use of 

 the Bordeaux mixture in 1895 it was decided to compare heavy 

 and light applications of this mixture in 1896 to see whether 

 heavy applications were more apt to do injury than light applica- 

 tions of a mixture having the same strength. Further investi- 

 gations as to the best time to do the spraying and the least 

 number of treatments needed were also planned. One hundred 

 and fifty-five trees were included in the experiments; part of
