898 EXPERIMENT STATION RECORD. 



case reported the product of the sprayed trees was of considerably bet- 

 ter quality thau of tbe uusprayed. 



The efficiency of arsenate of lead and Paris green applied with and 

 Avithout Bordeaux mixture was tested, and it w^as shown that the rela- 

 tive efficiency of the insecticides wdth aud without Bordeaux mixture 



was as follows : 



Average percentage of wormy fruit. 



Per cent. 



Arsenate of lead aud Bordeaux mixture 2. 15 



Arsenate of lead 5. 60 



Paris green 6. 38 



Paris green and Bordeaux mixture 6. 64 



Bordeaux mixture 7. 46 



Unsprayed 14. 45 



Lysol, which has been particularly recommended as a preventive for 

 peach curl, was tested in the greenhouse on a number of plants, 2 

 applications being given in which 1, 2, 3, and 4 per cent solutions were 

 used. With the exception of a solanaceous greenhouse plant aud helio- 

 trope, no injury was done by the applications. A li per cent solution 

 of lysol was sjirayed upon peach trees with no injurious effect, while a 

 Bordeaux mixture of 3 lbs. each of copper sulphate and lime and 2 oz. 

 of Paris green to 45 gal. of water badly damaged the foliage.
