Check 



Nicotine gave the best control and no injury was noted either from 

 it or the Scalecide from the first application but at the time of the second 

 spraying, considerable injury was done to the tender leaves on trees 

 sprayed with Scalecide, enough to warrant not using it for this purpose 

 when the fruit buds are showing color. However, it is possible that 

 Scalecide can be used effectively by making a late application for scale 

 and aiming to control the first appearing plant lice at this time. 



DRY ARSENATE OF LEAD AND ARSENITE OF CALCIUM AS A POISONED SPRAY FOR 



APPLES. 



The object of this work was to obtain data on the comparative value 

 of the two poisons as used upon apples for the control of the larvae of 

 the codling moth. 



Applications were made upon a collection of varieties and data taken 

 upon its effectiveness against the codling moth. Notice was also taken 

 of the point of entrance of the larvae as to whether it entered through 

 the calj^x or the side of the fruit.
