404 Report of the Horticulturist op the 



Experiments op 1895. 



Messrs. W. D. Barns & Sou, Middle Hope, N. Y., kindly offered 

 their orchard for the purpose of the experiments and cordially 

 cooperated in the work. The details of the work were under 

 the Immediate supervision of Mr. Paddock, the Assistant Hor- 

 ticulturist of this Station. 



One hundred and fourteen trees were set apart for the experi- 

 ments. They include three varieties, namely: Reine Hortense, 

 Early Richmond and Montmorency. Some of each variety were 

 left untreated for the sake of comparing them with treated trees, 

 some were sprayed with Bordeaux mixture and some with the 

 eau celeste soap mixture. 



Three series of treatments were planned. The treatments of 

 the first series were made May 1, May 14 and May 29. The treat- 

 ments of the second series were made May 14, May 29 and June 

 15. The first and only treatment of the third series was made 

 June 15. The buds were well expanded May 1, when the first 

 treatment was made, and the blossoms opened about four days 

 later. May 10, just after the blossoms had fallen, the second 

 spraying was made. 



A careful examination of the trees June 15 showed that up to 

 this time very little leaf-spot was present either on sprayed or on 

 unsprayed trees. The foliage on trees which had received the 

 eau celeste treatment was somewhat spotted, but this was prob- 

 ably largely due to the injurious elfects of the spray. The un- 

 treated foliage and that treated with Bordeaux mixture appeared 

 at this time to be perfectly healthy. 



Two weeks later, June 28, Mr. Barns reported that the trees 

 in series I, which had received the Bordeaux mixture treatment, 

 showed a little injury to the leaves, while worse injury was seen 

 on eau celeste treated trees of series II. The trees in series III, 

 which had received but one treatment with eau celeste, already 

 showed some injury to the leaves. On this account spraying 

 was discontinued, so that series III did not receive treatment 

 July 15 and August 15, as was first planned.
