INSECTICIDE, 

KILL THE PEACH TREE BORER 
BY USING PARADOW 
The borer feeds actively in the fall, spring 
and summer months, and lies dormant in the 
winter. It attacks the soft inner bark usually 
just beneath the ground and sometimes along 
the larger roots. The presence of these pests is 
indicated by masses of gum mixed with brown 
frass or “‘sawdust’’ exuding from the injured 
trunk. One treatment per year, preferably in 
the fall, will usually be sufficient protection. 
Paradow penetrates the burrows of the borers. 
It is fatal to insects but harmless to man or 
beast unless taken internally.
