Sunoco gmuiitying Spray Oil 
Scale insects include some of the most 
dangerous enemies of horticulture. They 
are small, but propagate so rapidly that 
neglected trees quickly become incrusted 
with them. Do not allow these scales to 
gain a foothold. Sunoco applied as a dor- 
mant spray will control most all kinds of 
scale. Rusty evergreens, caused by red 
spider, may be prevented by using Sunoco 
Spray in May or June.
