Eau Celeste, while less effectual than Bordeaux mixture in pre- 

 senting scab, was found to injure the foliage unless used with cau- 

 tion. The fruit also, was made somewhat rusty — the epidermis 

 apparently being injured by the ammonia. 



The relative value of the different materials used may best be 

 summarized as follows :

These differences are graphically portrayed in the accompanying 

 diagram, in which the shaded portion represents the per cent of 

 fruit free from scab.

and Paris Green. 



The concensus of opinion among experimenters at the present time 

 places Bordeaux mixture at the head of the list of fungicides. A 

 general summary of results obtained by the writer during the past 

 three seasons is as follows, the figures representing the per cent, of 

 fruit free from scab :
