A block of apple trees (Ben Davis) were sprayed with various in- 
secticides to control the codling moth. Black Leaf (1:50) allowed 
23 percent of wormy apples; sulphate of nicotine (10 oz. to 50 gal. water) 
allowed 30 percent wormy; and sulphate of nicotine (12 oz. to 50 gal.) 
27 percent wormy. Unsprayed trees were 41 percent wormy, and lead 
arsenate '(3 lb. to 100 gal.) allowed only 4 percent wormy. Nicotine pre- 
parations are of very little value, if any, in controlling the codling moth.

Apple trees were sprayed with Black Leaf Extract (l: 50) and 
Sulfate of Nicotine (l to 750). In regard to the first spray, 77 per- 
cent of the fruit was free from insect injury, and in regard to the 
second spray, 73 percent was free from injury. The check fruit was 
58.9 percent free of injury.
