THE USE OF ARSENATE OF LEAD FOR CONTROLLING THE 

 CODLING MOTH. 



By A. F. Burgess, Columbus, Ohio. 



Early in the spring of 1003 a series of experiments was i^lanned to 

 test tlie effect of spraying for controlling the codling motli. Tliis 

 insect had proved very destructive in an orchard at Delaware, Ohio, 

 and although some spraying has been attempted in previous years the 

 applications were not made in a systemati.c manner and the insect had 

 not been held in check. It had continued to increase in abundance, 

 and the loss resulting thereby had become so serious that systematic 

 treatment was rendered absolutely necessary if a j)rofitable croj) of 

 fruit was to be raised.
